The paper considers the models refinement of the deposits structure, located in the central part of the Samara region and controlled by the Yekaterinovsko-Karagai graben-like trough. The revision of the field structure models, taking into account the influence of the Devonian graben-like troughs, leads to the specification of the reservoir size and reserves amount, which makes it possible to reduce the risks for production drilling or increase the resource base.

To solve the considered problem of regularities in the development of hydrocarbon deposits in the terrigenous Devonian of the Samara region, depending on the graben-like troughs, the archive of deposits was analyzed, and a catalog of deposits was compiled, depending on their association with tectonic elements; the features of these deposits structure and production are analyzed; seismic materials within the deposits covered by 3D seismic surveys are considered; the prerequisites for revising geological models based on the seismic data are identified; the comparison of the deposits location with the network of the identified Devonian graben-like troughs is made; directions of further exploration prospects are indicated.

 

Keywords: graben-like trough; regional fault; tectonic deformation; Devonian terrigenous deposits; seismic exploration; reservoir model; field.

The paper briefly reviews the ideas about the stratification of the Neocomian deposits section. Seismic facial complexes were taken as a basis for geological modeling, instead of formation units, including reservoirs in the coastal shallow-water zone in a relatively deep-water isochronous clinoform formations of the Achimov strata. Within the investigated territory, the characteristics of the established oil and gas content of the complex are presented, promising objects are identified on the basis of 3D seismic prospecting, and their seismic-geological characteristics are given.

 

Keywords: the Western Siberia; lithofacies region; seismic complex; clinoform; promising object.

The process of creating and adapting geological and hydrodynamic models at any stage of field development has many uncertainties. To improve the reliability of geological and hydrodynamic models, it is necessary to use all available information. For undeveloped fields, these are the results of hydrodynamic studies of wells at the stage of advanced production, and for fields with a high level of knowledge, it is necessary to objectively integrate all available information. The paper discusses various approaches to improving the reliability of geological and hydrodynamic models.

 

Keywords: geological and hydrodynamic model; absolute permeability; hydrodynamic studies of wells; pressure build-up curve; indicator diagram; core; linear discriminant analysis.

The paper, based on the data of a wide-azimuth 3D seismic survey, presents a study of the geological structure of the Middle Jurassic and pre-Jurassic complexes of one of the fields in the West Siberian oil and gas province. Various aspects of seismic imaging, such as accounting for anisotropy, full-azimuth depth migration and separation of scattered and specular wave fields are considered. Methodological and technical aspects and general results of seismic and geological features of the targeted formations structure are also described.

The performed seismic and geological set of studies allowed thorough studying the geological features of the targeted formations structure.

 

Keywords: wide-azimuth seismic survey; depth migration; Tyumen formation; pre-Jurassic complex; sequence stratigraphy.

The purpose of this work is to improve the design of injection wells in a low-permeable reservoir to increase the efficiency of the reservoir pressure maintenance system. The object of the study is the West Siberian field, which has ultra-low reservoir properties. The producing and injection wells operation is analyzed, the zones of effective influence of reservoir pressure maintenance are identified. Multivariate hydrodynamic calculations are carried out, which differ in the design of injection wells (multilateral wells). The calculation results show that the drilling of a multi-hole injection horizontal well (HW) has several advantages: an increase in injectivity, in oil production rate and in total oil production.

 

Keywords: low-permeable reservoir; efficiency of reservoir pressure maintenance system; reservoir simulation modeling; multilateral well.

The development of water inflows limiting technologies is a top requested task of the oil producing industry, since one of the most pressing problems in oil production today is a high water-flooding of wells products. The LLC Research and Technology Company "Atombiotech" has developed an innovative technology for limiting water inflow in production wells "Temposceen-Plus", which has successfully passed field tests. The paper presents the results of laboratory studies of the rheological and physical-chemical parameters of the "Temposcreen-Plus" reagent and the polymer-gel system based on it. At the same time, the presence of thermotropic properties of the "Temposcreen-Plus" polymer-gel system (PGS) at a temperature of 80 and higher was observed experimentally.

 

Keywords: polymer-gel system (PGS); water inflow limitation; "Temposcreen-Plus"; rheological properties; thermotropism; physical-chemical properties.
