The paper presents the main criteria for drawing the border between the Alymsky (the Aptian stage) and the Vandensky (the Barremian stage) suits at the Orekhovo-Ermakovskoye field, located within the territory of Nizhnevartovsk arch. Correctly selected boundary based on the core material provided a uniform stratification of the layers AB13 (Alymsky suit) and AB21 (Vandensky suit) in the Orekhovo-Ermakovskoye field with similar deposits of the Nizhnevartovsk arch.

The paper is devoted to the urgent problem associated with a significant reduction of fund of the objects prepared for prospecting in the territory of Udmurtia, which, as a rule, refer to anticlinal structures. A promising direction of non-structural traps and oil deposits associated with them within the Tournaisian channel sandstone in the territory of the Udmurt Republic is considered. Based on the conducted analysis of geological-geophysical materials, the types of non-structural traps are allocated as well as their confinement to stratigraphic complexes and patterns of their distribution in Udmurtia. The conditions of their formation are determined and the zones of distribution detailing the types are identified. The scheme of zones with high probability of presence of different types of non-structural traps in the considered territory is made. The prospects and potential of non-structural deposits are estimated. The probabilistic estimation of the resources within the boundaries of the Tournaisian channel sandstone is carried out. Recommendations on the optimal complex of geological exploration for the study of non-structural traps in the area under consideration are given.

 

Keywords: the Tournaisian stage; Malevsky and Upinskiy horizons; terrigenous deposits; the Kama-Kinel system of deflections; channel sandstone; non-structural trap; deposit; oil.

The paper presents the approaches to construction of a simplified reservoir model, provided, that there is a confirmed inefficient injection in the reservoir. The simplified reservoir models based on the material balance equation are one of the components of integrated models and can increase the speed of performing short-term forecast calculations. The analysis of the applied model configurations is presented. Conclusions are drawn on the effectiveness of the considered approaches implementation.

Natural carbonate reservoirs have been studied for a long time and by now a significant amount of research has been done that enlightens various aspects of their productivity. However, the problem of studying the potential of carbonate reservoirs is still relevant today. The present paper assesses the potential of deeply buried carbonate section of the Alturitas oilfield located in the Maracaibo sedimentary basin. The tectonic history of the territory development and the sedimentological prerequisites for the hydrocarbon deposits formation in the section are considered. The initial data for petrophysical studies are given and systematized, the working method and the results obtained are described.

 

Keywords: the Cretaceous age; the Tertiary age; carbonate collector; fractured collector; Maracaibo sedimentary basin; lithotype.

The effectiveness of work on the injectivity profiles conformance control of injection wells using a solution of polymer clay-quartz composition (PCQC) at the experimental site of AV13 object of Samotlor field is analyzed. The additional oil production using various displacement characteristics, values of recoverable reserves and their increments are calculated The average additional oil production obtained within 24 months after the injection wells treatment with PCQC made more than 19 thousand tons, the total increase of the recoverable reserves is estimated at the level of 11,65 %, the decrease in water cut averaged 2 %. The suitability and success of the technology of the PCQC injection to increase oil recovery and extraction of residual oil reserves in the late stages of a field development is shown.

 

Keywords: injection well; injectivity profile conformance control; additional oil production.

This paper starts the authors series of papers devoted to methodological, technological, metrological and other aspects of conducting and processing the results of studying PVT-relations of reservoir oils of various physicochemical properties. The present paper presents a new algorithm for CCE-test results processing as well as proposes the validation criteria in order to control the quality of experiments. The application of the algorithm is limited by the cases of studies of "black oils", i. e., reservoir hydrocarbon fluids with pronounced signs of vapor phase formation.

 

Keywords: formation fluid; reservoir oil; dark oil; PVT-analysis; PVT-ratios; contact degassing; CCE test; swelling test; quality control.

The involvement of hard-to-recover oil reserves and the correctness of their development will increase the production of high-molecular raw materials for further processing. Most deposits of high-viscous oils and bitumen are developed by application of thermal recovery methods. Thermal recovery methods are understood as injection of coolant into the reservoir to reduce the viscosity of oil and increase its mobility in the reservoir. Heating in the productive reservoir is carried out by convection, and the roof and the bottom of the formation are heated due to the thermal conductivity.

The paper presents an experimental study of the influence of the rock pressure and heat-conducting warming on the open porosity coefficient of rocks. The experiments were carried out at a specialized "PIC-OPP/EP-K-T" unit. Based on the values of the open porosity coefficient measured by the volumetric method, two core models (low-permeable and high-permeable) were selected for a series of experiments. The core models were saturated by the formation water model with 30 g/l mass concentration of NaCl. The dependences of the open porosity coefficient on the rock pressure increase were built. The dependence of the open porosity coefficient on the temperature influence was built for the low-permeable core model.

 

Keywords: thermally conductive warming; core model; coefficient of open porosity; pilot study.

The relevance of the study is determined by the fact that in the process of clogging of the well bottom zone (WBZ) occurs already during its opening due to compaction of the rock during drilling, clogging with chemical reagents contained in drilling mud. During the operation of oil wells, their production rate decreases due to clogging of the WBZ by various types of asphalt-resin-paraffin deposits and salt deposits. To increase the permeability in the WBZ, it uses various methods, among which the most promising are physical, since they do not require additional expensive equipment. The purpose of this work was to analyze the existing acoustic equipment and technologies for its use in oil production, cleaning the bottomhole zone, by converting electrical oscillations into mechanical vibrations of the ultrasonic frequency range. Results. Existing acoustic equipment and technologies are briefly described: the essence of technology, firms developing equipment, a comparison of their technical characteristics, their advantages and disadvantages. A comparative analysis of the use of technology with other methods of intensification of oil production is given. Analysis of the results of field tests conducted by various oilfield service companies showed high efficiency in the application of acoustic technology to restore well production.

 

Keywords: oil; well; clogging; well bottom zone cleaning; acoustic equipment; acoustic technology; enhanced oil recovery; field test.
