Determination of saturartion coefficient in carbonate reservoirs

DOI:

Key words: Eastern Siberia, laboratory investigations of core, hydrocarbon saturation index, carbonate reservoir, hydrophobicity.

Use of standard research techniques doesn’t solve the problem of proper definition of hydrocarbon saturation index as well logging resistivity significantly exceeds core resistivity. On the base of the obtained relations “core well logging” and “well logging - well logging” there has been developed algorithm of calculation of hydrocarbon saturation index. The obtained results are typical for carbonate oil-wet reservoirs. There is presented a comparison of obtained results with the results of core investigations (including definition of residual water saturation).

Characteristic aspects of the Cenomanian deposits on the exampleof Russkoye field

DOI:

Key words: the Cenomanian, Russkoye field, incised valleys, microscopic lamina, permeability, heterolyte filling, tidal flats, sand storms.

The major reserves of Russkoye field relate to the Cenomanian formations PK_1-7 of pokurskaya suite that is characterized by a complex structure. That is determined by facies environment and uneven development of secondary processes. The integrated core study allowed specifying the Cenomanian deposition nature and determining within the field an “odd” different from the other in Western Siberia type of clastic reservoir. The “odd” type is represented by coarse-fine grained shaly (shale content is 12-20%) and sand (12-20% as well) silt stones in the deposits of heterolyte filling of tidal flats. The “odd” nature of deposits is determined by sand material localization as thin lenticular lamina (0.1-3.0 mm; up to 30-40 % for rock) with sharp boundaries and high permeability along the layers. The formation of shaly siltstones with sandy lamina relates supposedly to drought periods and eolation activation which lead to sand storms on the territory of tidal flats.

Extensive investigations of drilling mud for Sovetskoye oil field AB1 formation exposing

DOI:

Key words: “ryabchik” reservoir, Koshay suite, drilling mud, clay swelling, permeability restoration.

Because of attic oil on the low-permeable top of the continuous AВ₁ reservoir expanded program of horizontal drilling was initiated for of Sovetskoye field (Western Siberia, Russia). As shaly interval stability is a specific issue in horizontal wells special attention is always paid to the drilling mud and seal shaly material interaction (incl. clay swelling and disintegration). Again, any mud used should not damage greatly the formation. For the set of 7 drilling muds lab tests were conducted to recognize the optimal composition which is both does not collapse a shaly seal of Koshay suite and recognized the best permeability to oil restoration for the reservoir. As a result two mud composition (Megadril™ and 1,08 g/cm³ Flo-Thru™) were suggested to use.

Non-stationary water injection as a way of waterflood system performing

DOI:

Key words: non-stationary water flooding, cyclic water flooding, direction change of filtration flows, hydrodynamic EOR methods, optimization formation pressure maintenance system.

Currently water flooding implementation represents the major condition for successful depletion of oil fields’ pay zones. However, in case of a high reservoir heterogeneity water flooding performance reduces due to irregular distribution of injected water. One of the accessible methods of displacement front alignment is conversion of the implemented flood pattern to a non-stationary operation. This work reviews the possibility to implement non-stationary water flooding in Sorochinskneft fields, it also determines the top priority development targets for the method implementation, and a program of non-stationary water flooding is prepared for a pilot area along with its performance evaluation.

DOI:

Key words: multidisciplinary studies, geological uncertainties, reserves progression, petrophysical evaluation, seismic studies, reservoir modelling, production forecast, offshore platform capacity, processing de-bottlenecking.

Power sector consumes the majority of gas production in Vietnam. During the past 11 years of gas and condensate production, Rosneft Vietnam successively increased hydrocarbon reserves and platform processing capacities in order to meet contractual obligations and secure the production until the end of Production Sharing Contract. Gradual reserves progression was achieved due to comprehensively multidisciplinary studies from petrophysical re-evaluation and seismic re-interpretation to recovery factor re-estimation. Continuous reserves progression together with market demand dictated the need of offshore platform processing capacity de-bottlenecking. The paper describes a successful story of several projects implemented to significantly increase platform capacity from its original design. The paper offers several key successful factors for effective enhancement of reserves and production capacity improvement.

Typical sections of Bashkirian carbonate rocks and structure of oil deposits in southeast part of the Republic of Tatarstan

DOI:

Key words: Bashkirian stage, structure of oil deposits, limestone, reservoir, petroleum, typical sections.

Carbonate rocks of Bashkirian stage are regional oil saturation in southeast part of the Republic of Tatarstan. Bashkirian reservoir rocks are not all oil saturation that is caused by environments of carbonate sedimentation. We suggest sedimentation scheme and typical lithological sections of Bashkirian layers. Lithological typification and reconstruction of sedimentation carbonate rocks allows to prospecting oil reservoir. Reservoir type of limestone irregularly detect in Bashkirian sequences. They can form massive and multilayer oil reservoir. Often, section absent reservoir limestone, so this section non perspective for oil development.

Research of polymer drilling muds impact on core-derived evaluation of reservoirs properties

DOI:

Key words: polymer drilling muds, core, porosity, permeability, specific electric resistance.

On the example of a field in Orenburg region the authors researched an issue of adequate data obtained when analyzing the core taken using the polymer-clay drilling mud. It was shown that the drilling muds based on the polymers of polysaccharide class do not exert any significant distorting impact on the defined-by-the-core basic parameters (porosity, permeability, and electrical resistance at 100 % water saturation). In the meantime, when researching the rock samples of cavernous and porous type we should take into account the occurrence of transformation phenomenon of the porous space geometry as a result of separation of the particles of the rock matrix by the action of the water that is filtering through it, which may cause an artificial understatement of permeability after the water wash of the core.

Research of expanding ability of the cement slurries made on the basis of oil-well cement

DOI:

Key words: oil well, cementing of casing, expanding cement slurry, technology of casing, quality of casing.

Application of cement slurries for cementing of casing of oil and gas wells without modifying additives on the basis of common oil-well cement often leads to emergence of cross-flow between beds right after cementation, as a result of their shrinkage. The authors developed expanding cement slurries on the basis of a common oil-well cement PCT-I-G with modifying additives. Researches of dynamics of increase in their linear expanding depending on type and quantity of expanding additives are conducted. Results of the trial tests of the developed expanding cement slurries are presented.

Production forecast for Prirazlomnoye oil field in conditions of oil-water zone structure uncertainty

DOI:

Key words: transition zone, phase permeability, the Monte Carlo method, simulation.

On the basis of the hydrodynamic model using statistical modeling estimated is the impact on the dynamics of oil withdrawal of three uncertain factors: changing the position of the oil-water contact and the surface boundaries of the transition zone, while maintaining the value of the initial oil reserves; possible variations in the density of heavy oil; change in the distribution of zones of different phase permeabilities in the reservoir. Mathematical modeling of the 100 realizations of PVT properties of oil-water zone showed good stability of the base variant of development with respect to changes in these factors. The bulk of the realizations leads to minor changes in the design dynamics of production, although the variation in the cumulative production for individual wells is much larger.
