Abstract:

The increasing demand for petroleum products will require the production and the upgrading of heavy and extra-heavy oils. Hence, the petroleum industry is confronted with many issues in production, transportation, and refining. Indeed, petroleum residues are complex mixtures of high molecular weight compounds containing high amounts of impurities such as sulfur, nitrogen and metallic species. These elements need to be removed in hydro-processing units through hydro­desulfuration, hydro-denitrogenation and hydro-demetallation reactions before these oil fractions can be used. The most abundant metals in heavy feedstocks, vanadium and nickel, are mainly concentrated in the asphaltenes fraction, a petroleum fraction which precipitates in presence of paraffinic solvents. Characterization of vanadium and nickel complexes is therefore important to the development of demetallation and conversion strategies used to process heavy crudes. The dependence of vanadyl structures on the geographic origin of feedstocks and their evolution during hydroprocessing in an ebullated-bed pilot unit were studied. The aim of this contribution is to assess the possibilities of the EPR spectroscopy to provide information on the structure of the vanadyl species. Two Venezuelan Straight Run Vacuum Residues (SR VR), and one Russian SR VR, were hydroconverted at 410°C in an ebullated-bed pilot plant. By comparing the spectrum of VOTPP (vanadyl tetraphenyl porphyrin) reference with those of C7 asphaltenes, it seems that nitrogen ridges are composed of two types of signatures which are attributed to nitrogens chelating the vanadium or are very close: one of them corresponds to nitrogen nuclei that are very close to the signal of the VOTPP nitrogen (noted N₁), but the other one has not been attributed (noted N₂).This work shows that pulsed EPR spectroscopy is a powerful technique that allows to distinguish several types of environments of vanadium species, amongst which are porphyrinic ligands, even in very complex samples such as C₇ asphaltenes from heavy feedstocks. It was shown that the relative proportions of vanadium species vary from one feed to another depending on its geological origin, and that the porphyrinic species in asphaltenes from hydroconverted effluents are more refractory to conversion. It will be very interesting to characterize more hydroconverted effluents to confirm the refractory character of porphyrinic species and to see whether pulsed EPR is able to follow the evolution of the second coordination sphere to better understand the mechanisms of hydrodemetallization.

Abstract:

In past 5 years, CNPC has made great breakthrough of shale gas exploration and development in Sichuan Basin. Both proved reserves and production rate has been growing rapidly. This is achieved by the advance and innovation of technology and management.

a) Geology and geophysics technologies ensure the reliability of resource evaluation and production target. It is realized by acquiring, processing and interpreting geophysical data to obtain the stratigraphy correlation, sweet spot distribution, key geology & geomechanics factor determination.

b) Drilling and completion technologies provide the early return of the investment. CNPC has explored the best practice of integrated technology (including fasting drilling, volume fracturing treatment), to obtain higher initial production rate (over 6.4×104 m3/d per well in Changning and Weiyuan plays).

c) Reservoir engineering technology ensures the long-term sustained production. Gas well classification is developed to perform integrated management of numerous production wells; production performance evaluation is developed to estimate OGIP and EUR (average OGIP per well is 1×108m3, EUR is 7.6×107m3/d); fracturing parameter optimization is developed to enhance productivity and benefits.

By conducting these pilot research since 2012, CNPC has established complete technique series for the development of shale resource buried less than 3500m, and gained great confidence from accomplishing production from shale.

While CNPC has made great progress towards commercial production, low gas price and high investment are expected to be growing challenges in the way ahead for shale gas. CNPC would realize cost-effective production at low gas price by sustained improvement and innovation of technique.

Abstract:

Small scaled surfactant flooding test was implemented field at Tanjung Field. Zone A reservoir selected for this test has estimated IOIP at 193.7 MMSTB. The current recovery factor is 16.3%. This field had been produced since 1961 under primary depletion until 1989. At 1990 pilot waterflood was started and since 1995, this field has been undergoing full scaled water injection until today using peripheral pattern. Zone A is a very tight conglomeratic sandstone layer that has effective porosity (f) of 21%, average initial water saturation of 35%, and permeability (k) of tens to hundreds md. The oil gravity is 40°API, wax content is 36%, dead oil viscosity (m_o) is 7.9 cP (live oil viscosity is 1.14 cp), initial reservoir is 1600 psi, bubble point pressure is 1357 psi and reservoir temperature is 150^oF. A type of Alkyl Carboxy Etoxylate surfactant was used and was formulated further suited to oil and characteristic of reservoir. This formulation was optimized using salinity scan method and addition of co-solvent to obtain Type III phase behaviour and low IFT of 10^-2 mN/m (initial oil-brine IFT was 18.3 mN/m). It was stable up to 150^oF for three month. Core flooding experiment was conducted using native core, brine and oil. After saturation of core to established initial water and oil saturation, brine was injected until 100% water cut followed by slug of 0.2 PV surfactant solution (2% w/w concentration) then by water injection. Incremental oil recovery was 25%. Small scaled field testing was conducted by selecting pair of injector-producer that was at close distance and has good connectivity between them. The primary objective is to confirm the surfactant performance at the field. The response should be quick enough and be cost efficient to enable further review. The injection pattern was a line drive like with target reservoir pore volume is 10,625 bbl. Total cost of this test was only USD 61,812 (include chemical and operational costs) and oil production was increase up to three times. This surfactant flooding test is started at 18^th of January, 2016 and injected continuously for four days followed by water injection. First oil production gain was recorded after surfactant slug was completed and it has been maintained until 22^nd of June, 2016 and counting. Incremental recovery of this small scaled testing is 72.4%.

Abstract:

The total global energy of CH₄ trapped in crystalline form as hydrates is huge and may exceed twice the amount of energy of known sources of conventional fossil fuels. Most of the natural gas hydrates found in nature are from biological degradation of organic material in the upper few hundred meters and correspondingly high purity of CH₄. These hydrates forms structure I hydrate, which contains a ratio of 1:3 of small to large cavities. The small cavity is very well stabilized by CH₄ while CO₂ fits the largest cavity better, and the water is having stronger short range interactions with CO₂ than CH₄. CO₂ gas or liquid that is brought in contact with CH₄ hydrate will therefore replace the CH₄ in most of the large cavities. This is possible through two mechanisms, a solid state direct conversion and a second mechanism in which CO₂ form a new hydrate with free pore water. The released heat from this hydrate formation assists in dissociating the in situ CH₄ hydrate. Substantial amounts of N₂ (often as high as 80% by volume) is proposed as one solution for reduced hydrate plugging and increased gas permeability. In this study we examine the minimum limits of CO₂ content for ability to form new hydrate from liquid water and injected gas, and also how this changes with small impurities of H₂S. It is found that even as small amounts of H₂S as 1% can substantially increase the ability of injection gas to form new hydrate, as compared to same mixture without H₂S.

Abstract:

The exploitation and production technologies of shale gas and its regulatory aspects are discussed, focusing on analysis for decision-makers. The data collected comprehended technology assessment through patent applications, scientific research evaluation through articles, regulatory aspects and accidents. This work maps countries, authors and journals with more articles, and companies with more patent applications. Several relationships and networks are discussed: Between authors and articles, among the main themes of articles, among countries with articles, and among 37 International Patent Classification codes. The environmental legislation is discussed for 9 countries and over 20 states, yielding regulatory analysis in several countries and in Brazil. A risk map is presented showing the geographic distribution of accidents. The main themes found are health, water, pollutant emission, regulations and policies, economic aspects, environmental impacts, risk and shale gas characteristics. It was found that there are few alternative technologies to hydraulic fracturing, being the research efforts more concentrated on mitigation technologies. United States and China are the countries with greater scientific and technological production as these countries possess large reserves of this resource and great interest in expanding their scale of operation and commercialization of this raw material, as well as export technologies. This work points several items of technical and sociological assessments of the production of shale gas, highlighting the need for better technical evaluation and better structuring the regulatory aspects, aiming to the possible exploitation of shale gas on large scale in Brazil.

Abstract:

In this study, rheological properties of heavy crude oil from mature fields of India are premeditated. Effects of pressure and shear on viscosity followed by viscoelastic properties such as gelation point, crossover amplitude, and crossover frequency are profoundly studied by carrying out constant shear, frequency, strain and temperature sweep experiments on High Pressure Anton Paar Rheometer. Gelation temperature apprises about the ambient temperature to maintain inside the pipelines for flow assurance i.e. just above the gelation point so as to avoid the formation of wax/gel which can lead to blockage of pipe and even shut down in extreme conditions. Storage and Loss modulus are stress responses for a viscoelastic fluid under oscillatory shear. Important feature of temperature vs. G’ and G” is the crossover point, which is the temperature at which G’ and G” intersect (in case of reactive media) or there is a sudden increase in the value of G’ (in the case of non-reactive media). At crossover point gel formation takes place and with further decrease in temperature the microstructure tends towards a solid structure. While as temperature increases from crossover temperature,G">G' this is the instant when the applied mechanical force surpasses the inter-molecular forces and the material starts to flow. Viscoelastic measurements characterizes material similar to optical spectrum, UV & IR Radiation having the advantage over latter of very less sample requirement and satisfactory results acquired in small deformations.

Abstract:

West Siberian Jurassic-Cretaceous sedimentary basin developed as a huge syneclise, including (in the north-east) Yenisei-Khatanga regional trough within the ancient Siberian platform. In the lower part, the Cretaceous deposits of Western Siberia clinoforms are widely developed. In the 70s of the twentieth century, A A Naumov connected them with the nature of filling the sedimentation basin. In 1988, T F Kalmykov explained the formation of the inclined reflecting areas by tangential stresses during passage of this huge syneclise through the chord of earth’s ellipsoid. Possibly clinoforms were created due to the pressure of Taimyr folded zones on margin of the Siberian platform. In support of the tectonic conditioning of Lower Cretaceous clinoforms, there is evidence by clear manifestation of them on the western slopes of the numerous uplifts within the eastern part of the West Siberian basin. The amplitude of these uplifts is saved from Pre-Neocomian horizons to the roof of Neocomian that indicates their later formation. Explanation of conditions for the formation of Lower Cretaceous clinoforms ("oblique packs") in Western Siberia is essential for the prediction of their abundant oil content. When consedimentational genesis oblique lens of sandy rocks, potential reservoirs, are isolated in the argillite-siltstone matrix that make problematic filling with oil for them. When they are formed by the action of tectonic stress there created the conditions for slippage of different lithology lens on surfaces of disruption, which may be further used as hydrocarbon migration paths.

Abstract:

In several publications since 2012, Marcoulaki and co-workers developed a systematic optimization framework for the basic design of main pipeline systems used for the transportation of fluids, like natural gas, petroleum or water. This presentation demonstrates the established optimization framework on real scale problems. The selected application involves the design of the Burgas-Alexandoupolis pipeline. The project has been under consideration since the 90’s, as an overland route for transporting crude oil from Russia and other countries of the Caspian region to the European markets and a trilateral agreement on the construction of the pipeline was signed between Bulgaria, Greece and Russia on 15 March 2007. The project was frozen in 2011 due to concerns for environmental and safety risks, but interest on the project was recently revived in view of increases in the capacity of the CPC. In our approach, the design problem is formulated mathematically and treated with advanced optimization techniques to derive optimal network structures and pipeline operation strategies, according to given fluid supply/demand, flowrate and location data, hydraulic equations, equipment cost, reliability, operation and maintenance features, and information on the landscape features and land use. We consider geographic data, including DEM’s, the location of SEVESO installations and geological fault lines, as well as the network of cities and roads, lakes and rivers, sites of environmental interest, etc. The solutions generated by our tool conform to various constraints, addressing safety, environmental and political issues, and compares favourably to the design proposed by the TBP Company.

Abstract:

The most effective ways of processing of a well – hydraulic fracturing, torpedoing, chemical processing are most expensive, ecologically dangerous technologies. In most cases creation of long cracks of hydraulic fracturing is unprofitable – gives low effect and leads to flood.

I suggest to apply the pulsing hydraulic fracturing pressure to creation of a network of short cracks.

1. It is economic, the constant high pressure isn't required, powerful pump units aren't used, the technology of multistage hydraulic fracturing isn't applied, a large number of people and equipment isn't required.

2. Cracks extend in all directions, inflow of oil is carried out from all directions.

3. On it is required to fix cracks by a proppant. After repeated processing aren't closed by pressure of a crack yes of the end.

4. The chemical reactants which are negatively influencing ecology aren't applied.

5. Application for extraction of slate oil and gas is especially effective.

Example. The technology of pulse and wave processing for delivery wells which I developed is repeatedly tested on crafts of the Volga region, Kazakhstan and China. For work hoisting works aren't used, 2 cars are used, work is carried out by 2 persons. The technology is successfully applied.

Together with National Mineral resources university work on creation of hydraulic fracturing in coal layers for preliminary removal of methane is carried out.

The pulse and wave technology of creation of cracks for the extracting oil and gas wells passes tests, in the industry isn't applied yet.

Abstract:

Nowadays, more and more attention is directed at the production of alternative environmentally friendly fuels, thereby reducing dependency on crude oil and yielding associated improvements in air pollution mitigation. There are a number of options available for example biogas, hydrogen or dimethyl ether (DME), with the latter being one of the more promising alternatives. DME is the simplest ether structure and the absence of a C-C bond means fewer undesired combustion by-products such as hydrocarbons or particulates generated. DME is mainly produced in one of two ways; the indirect method whereby methanol is dehydrated over a solid catalyst or increasingly by the direct synthesis method from synthesis gas over hybrid catalysts comprising a metal oxide to facilitate methanol synthesis and a solid acid for methanol dehydration (MTD) reaction. Here solid acid catalysts such as γ-Al₂O₃, crystalline aluminosilicates, zeolites (ZSM-5), and phosphates including aluminium phosphate are employed, with the most common being γ-Al₂O₃ and zeolites. The main objective of this work is to investigate and compare the potential benefits from loading Cu onto such alumina for the dehydration of methanol to DME.

Abstract:

Recently, we polymerized a block copolymer that was constructed of two monomers: A monomer with a long alkane side-chain (more than 10 carbon atoms) and another monomer with solvent affinity. This block shows side-chain crystallization. Thus, this block copolymer can crystallize due to its long alkane side-chain (Side-Chain Crystalline Block Copolymer: SCCBC). We found that the side chain block of the SCCBC is adsorbed on PE crystal. At this time, PE crystal and the side chain block of SCCBC are considered to form a quasi-crystalline structure. According to this, the solvent affinity block unit covers the particle and changes the particle surface easy to wet solvent. This is because, SCCBC can act as a dispersant for a concentrated PE particle dispersion. In this time, we added only 0.5 wt% of SCCBC to wax/oil mixture.  Without the SCCBC, the wax/oil mixture was solidified at lower temperature, however with adding the SCCBC, the wax/oil mixture was not solidified and we could measure the viscosity and viscoelastic modulus. We also found that the crystalline structure of wax was changed with adding the SCCBC.

Abstract:

In recent years, Chinese oil companies and Iraq's oil companies cooperate in exploration and development project under the service contract model. Iraq service contract mode has its unique way of income distribution and harsh terms of the fiscal taxation, which bring risks to relative investment company. Combined with the current situation that international oil price fluctuation is bigger and more frequent, the current situation of international petroleum is very serious and the risk factors of social environment have upgraded again. This paper not only explores the service contract pattern, finance and tax terms analysis financial risk factors on the impact of China's oil companies through forecasting the future of the international oil price trends, but also put forward advice on how to avoid financial risk. This article suggests the cooperation risk factors that China's oil companies should consider in advance under the international petroleum environment of the in the service contract mode, in case to mitigate risks in time.

Abstract:

The oxidation of cyclohexane, important in the production of the nylon monomers adipic acid, hexamethylene diamine and caprolactum, is one of those processes which, in spite of a tremedous amount of research effort, has resisted any substantial improvement in terms of the selectivities achieved. Industrial conversions have to be limited to about 4-8% in order that the selectivity to the primary products of alcohol and ketone (the mixture being known as KA-oil) does not suffer seriously. While soluble cobalt catalysts are commonly used in industry, environmental concerns and potential improvements have been powerful driving forces towards heterogenization. This talk reports on a new generation of synergistic, ketone-selective, cobalt-molybdenum mixed oxide catalysts, which provide a conversion of about 7.5% with a KA-oil selectivity of about 94%. The most promising of these catalysts, CoMoO₄-11 (with a Co:Mo ratio of 1:1), has been studied in detail and the kinetics modeled. The catalyst is deactivated at higher conversions by product adsorption, but the activity is completely restored on recalcination. Studies have also been carried out on supporting the catalyst particles on mesoporous silica supports to facilitate use in industrial processes, and the results with FDU-12 are particularly encouraging. An interesting feature of the catalyzed oxidation is the significant contribution of the uncatalyzed reaction, which at times makes for somewhat counter-intuitive trends.

Abstract:

This paper mainly describes the impact of oil price changes on several key aspects of the Chinese economy and come to a result through long and short-term empirical studies of changes in international oil prices and the national economy, especially through the study of second and third industrial relations: In the long run, international oil price volatility is not obvious, it already keep steady for 20 years and there is no significant causal relationship between rapid development of national economy and the change of oil price; under short-term conditions, rising oil prices showed a significant effect on the national economy of the second and tertiary industries, In addition, oil prices rising is usually before the economic changes. To strengthen China's oil security and reduce the impact of changes in oil prices on the national economy, this paper put forward counter measures and suggestions.

Kyeong H Park obtained his MEng in Chemical Engineering at University College London (UCL) in 2013. He started his PhD in September 2013 at the same institution. His study focuses on flow pattern transitions in oil-water flows.

Abstract:

In the petroleum industry, the characterisation of multiphase flows in pipes is of fundamental interest in both upstream and downstream processes, such as drilling, transportation and separation. When oil-water mixtures are transported, different flow patterns occur depending on fluid flowrates and properties together with pipe diameter and material. Understanding such flow dynamics is crucial as different patterns largely influence heat transfer, pressure drop as well as corrosion of pipes and the pump power requirements. The current study focuses on liquid-liquid flows in horizontal pipes and more specifically on the transitions from stratified to dispersed flows and the development and separation characteristics of unstable dispersed flows along the pipe. The experiments were carried out in an acrylic test section with 37 mm ID. Tap water and a kerosene oil (Exxsol D140; ρ=830 kgm^-3 and µ=5.5 cP) are used as test fluids. Different flow patterns have been observed and the flow conditions where the transition between the flow patterns occurs were identified. Pressure drop and conductivity of the mixture at the pipe periphery were measured at different axial positions along the pipe revealing the development of the flow patterns. In dispersed flows, drop size changes along the pipe were also recorded that were linked to the tendency of the two phases to separate.

Abstract:

Wax can precipitate as a solid phase on the pipe wall during production when its temperature drops below the Wax Appearance Temperature. Wax deposition can result in the restriction of crude oil flow, creating pressure abnormalities and causing an artificial blockage leading to a reduction in the production. A series of experiments were carried out at different flow rates (2.7, and 4.8 litre/min) to study and measure the wax thickness. The performance of some of wax inhibitors was evaluated to determine their effects on the wax appearance temperature and the viscosity of the crude oil using the programmable Rheometer rig at gradient temperatures (55 – 0°C) and shear rate 120 1/s before and after adding 1000 ppm and 2000 ppm of inhibitors to the crude oil. Three different inhibitors which were not tested before were prepared in the lab of this study. These inhibitors works efficiently compared with its original components. The first inhibitor was coded Mix01 by mixing polyacrylate polymer (C16-C22), and copolymer + acrylated monomers. The reduction of pour point of the waxy crude oil was up to a 16.6ºC at 2000 ppm concentration and this reduces the crude oil viscosity to about 61.9% at a seabed temperature of 4ºC. The second inhibitor was coded Mix02, by mixing polyacrylate polymer (C16-C22), alkylated phenol in heavy aromatic naphtha, and copolymer dissolved in solvent naphtha. At 2000 ppm, the reduction of pour point of the crude oil up to a 15.9ºC and decreases the viscosity to 57% at a seabed temperature of 4 ºC. Finally, the third inhibitor was Mix03, by mixing polyacrylate polymer (C16-C22), and brine (Hâ‚‚O+NaCl). At 1000 ppm concentration, the reduction of pour point of the oil was up to a 14.4 ºC and reduced the viscosity to 52.5% at a seabed temperature of 4 ºC. This unique blend of the inhibitory properties and significant reduction in pour point temperatures and crude oil viscosity is providing a novel progress in flow assurance technology.

Abstract:

A liquid organic hydride couple, methylcyclohexane (MCH) – toluene (TOL), has been industrially considered as potential and effective route for efficient hydrogen storage and transport. The beauty of this process is that the hydrogen is chemically bound to a liquid carrier with high gravimetric and volumetric energy density at ambient pressure and temperature. Moreover, the system upholds a closed carbon cycle which significantly diminishes the chemical and thermal pollution formed by greenhouse gas emission. It is, however, essential to have very selective catalysts for both hydrogenation and dehydrogenation to close the mass balance. It has been reported that the Pt based catalyst is the only selective catalyst for the dehydrogenation of MCH to TOL which is disadvantage due to its high cost. Thus, it is required to develop non-noble metal catalysts that can substitute Pt, making the process cost-effective and wide availability. Ni is a well-known dehydrogenation catalyst, but the major drawback of Ni based catalyst in this dehydrogenation reaction is its hydrogenolysis activity leading to inferior selectivity. The aim of this research is to find an alternative non-noble multi-component catalysts that can show excellent catalytic performance, particularly achieving high selectivity comparable to that of Pt based catalysts. Ubiquitous bi-metallic nanoparticles catalysts have been synthesized using homogeneous deposition precipitation method. Among the catalysts investigated, the Ni-Zn based catalysts have shown outstanding high selectivity of TOL (>99% at low conversion), with an only trace amount of benzene and methane as the major by-products comparing to the corresponding Ni based catalyst. The main role of Zn over Ni based catalyst in promoting the selectivity towards dehydrogenation of MCH to TOL will be discussed.

Shale reservoirs have become a major source of natural gas with the United States leading in production. This has led to new and innovative techniques which have led to improvement in exploration and production techniques. The process of quantifying adsorption is through experimental methods with results fitted to an isotherm to determine the total adsorbed gas. This study was conducted with the aim of fitting four isotherm models, namely: Langmuir, Freundlich, and Redlich Paterson to correlate experimental adsorption data using cored clay rich shale to determine the best fit isotherm. In order to determine the best, experimental methane adsorption data of two cored clay rich shale (Bandera, Scioto) were fit to isotherm models by non-linear regression using Mat lab R2016A software. Fitting results indicate that the Redlich Paterson model fit Bandera methane adsorption data better than the Langmuir, Freundlich or Sips model for the Bandera sample. For the Scioto, the Langmuir fit better than the other isotherms. These suggest that both Langmuir isotherm model and the Redlich Paterson isotherm model can generate a satisfactory fit to the experimental data, while Freundlich isotherm model cannot, the order of the isotherm best fits for the two clay rich shale samples are Redlich-Paterson >Langmuir> Freundlich. A number of studies have been conducted on organic shale and kerogen and fit to two or more isotherms to determine the best fit, but to our knowledge, this is the first study that has been carried out on cored clay rich shale to determine the best fit of adsorption isotherm.

Maria Astrid Centeno is doing her PhD at London South Bank University. She has a Master’s degree in Drilling Engineering and is a Senior Lecturer of Petroleum Engineering at London South Bank University. She has eleven years of progressive experience within the petroleum industry, six years in the academic area with experience as Senior Lecturer in Petroleum Engineering courses. She did a research project in chemical flooding enhanced oil recovery.

Abstract:

The success of polymer flooding as a method of oil recovery has been attributed to the profile control mechanism depending on properties such as viscosity, concentration and molecular weight. As polymers are injected in the reservoir, are exposed to chemical, physical and mechanical degradation processes depending on reservoir characteristics, fluids, temperature and pressure. Therefore an extensive screening process that include evaluation of variables such as polymer stability to salinity, temperature and flow conditions between others need to be considered in the selection of the best system for EOR(Enhanced Oil Recovery) for any particular oilfield screening case. A systematic study and screening of commercial polymer PHPA (Partially Hydrolysed Poly Acrylamide) and modified comb-polymer for effective application on a sandstone reservoir under high salinity multicomponent brine, with divalent ions Ca²⁺ and Mg²⁺ is presented. Polymer HPAM (hydrolyzed polyacryl-amide) of different molecular weights was compared with special modified co-polymers. Rheological results were adjusted according to correlation between viscosity, salinity, shear rate and polymer concentration. Core flooding experiments were performed using a sample of crude oil from the North Sea that has specific gravity 21ºAPI and Bernheimer sandstone core samples. Synthetic brine was prepared considering a composition of production water from a reservoir at the North sent Sea with high content of divalent ions Ca²⁺ and Mg²⁺. The reported viscosity of polymer solution increases with polymer concentration. There was a stronger effect for high molecular weight polymer, whereas viscosities of copolymers were less affected by polymer concentration than PHPA polymers. Core flooding experiments were numerically simulated to compare the efficiency of the different polymers. Results showed that polymer PHPA with high molecular weight (MW) can be effective for EOR applications because less amount of polymer is required to achieve high viscosity under high salinity conditions. However, this polymer was more affected by changes in shear rate than polymers with low molecular weight.

Abstract:

Conventional polyolefin-based thermoplastic elastomers have a variety of merit. But the copolymers including block, graft and blend types have some limitations due to their low use temperature. In this study, novel polyolefin-g-poly(t-butylstyrene) as one of the promising high utility temperature polyolefin-based thermoplastic elastomers was synthesized by the graft anionic living polymerization from the initiation of styrene unit form the poly(t-butylstyrene) hard grafts along the poly(ethylene-ter-1-hexane-ter-divinylbenzene) backbone as the soft block (0.3~0.5 mol% of graft sites). Phase-separation occurred in these polyolefin TPEs when the Mn of poly(t-butylstyrene) was more than 5,000 g/mol, which was evidenced by the presence of two distinct Tgs(-20°C of polyolefin soft block and 125°C of poly(t-butylstyrene) hard block) observed in DSC and DMTA. These high temperature polyolefin TEPs exhibited distinct mechanical property with high modulus and toughness even above 125°C. And when the content of P(t-butylstyrene) over 28wt%, excellent mechanical properties: high tensile strength (>21MPa) with high elongation (>1,100%) could be obtained, similar to that of S-EB-S(30wt% styrene content). The multi-carboxyl functionalized polyolefin-g-poly (t-butylstyrene) could be synthesized by the incorporation of high vinyl oligo-isoprene at the end of poly (t-butylstyrene) hard block via sequential anionic polymerization followed by the thiolene click reaction with thioglycolic acid to incorporate multi-carboxyl groups at the pendant vinyl units. The contact angle of these result multi-carboxyl functionalized polyolefin (12-COOH/molecule) was decreased to 58° compared to 95° in case of the non-functionalized polyolefin TPEs.

Abstract:

Petroleum products play an important role in economic development of any nation. At present oil producing sector takes a leading position in the structure of national economy of Kazakhstan. Kazakhstan's oil producing sector is quickly developing. Crude oil production grew from 40 in 2001 to 80 million tons in 2015 i.e. for 2 times.

The oil and gas basins of Kazakhstan can be grouped into four revealed or prospective oil and gas provinces in the Republic of Kazakhstan. They are:

1. The Pre-Caspian Basin lies in the western part of the country, behind the Mugodzhary Mountains. The geology of this province is made up of Paleozoic sediments covering a Proterozoic basement.

2. The Mangistau-Usturt Basin lies in the Mangistau and Aqtobe areas of Kazakhstan.

3. The Central Kazakhstan Basin lies in the eastern and southern areas of Kazakhstan.

4. The Western Siberian Basin is in the northern and northeastern region of Kazakhstan, north of the Kokshetau Mountains. The geology is of a platform type, with a Mesozoic cover overlying a Paleozoic basement.

Also, in the territory of Kazakhstan discovered huge amount of oil sands, which accumulated in over 50 fields. Its reserve is more than conventional oil of Republic. These oil sands resources are called unconventional oil to distinguish them from oil which can be extracted using traditional oil well methods. Oil sands situated in Western part of Kazakhstan, such as Aqtobe, Atyrau and Mangistau regions.
