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.
