Geoscientist’s Tools for Oil and Gas Fields Studies

(Larin G.V. )

Native modern D V series software of the 3D seismic and geological modeling, included in the line ofprogram modules open platform TimeZYX are considered. Their characteristic in comparison with the basic foreign analogues is given. It is shown that their application by experts of a various profile at all phases of geological and geophysical research and development of oil and gas fields, and also at construction of regional geological models, allows to carry out effectively the complex analysis of the multidisciplinary data and to obtain three-dimensional geological and hydrodynamic models.......

Should We Quit Grouping for Single Geophones?

(Cherepovskiy A.V. )

Large geophone groups as an instrument for regular and random noise suppression were developed and improved in the era of 2D seismic and analog recording. But the length of geophone groups became smaller and smaller with the advance of 3D seismic, high-density surveying, and digital recording. As a result, short geophone groups are now applicable only for suppression of random noise. But even short geophone groups result in significant attenuation of high-frequency signals, thus degrading high- resolution imaging and corrupting amplitude information.......

Structural and Tectonic Zoning of Subsalt Sedimentary Rocks of the North-Eastern Pre-Caspian Depression. Seismic Case Study

(Cherdabayev Zh.M. )

Studying on 2D CDP seismic materials geological structure of the territory located at the Pricaspian basin northeast side zone referred to the Volgograd-Orenburg monocline system. The studies resulted in identification of four structural-tectonic areas of various geological structures. These are Koblandinsko-Tamdinski, Novo-AIexeevski, Shirakski and Bestau-Sorkolski, within which potential oil-and-gas-bearing structural-facial targets are present.......

Determining Reservoir Rock Characteristics of the Abalakskian Suite (Krasnoleninsk Dome)

(Zyryanova I.A. )

Reservoir characteristics, reservoir delineation and porosity estimation of the Abalak formation of the Krasnoleninsk field are presented here. The deposits are mainly composed of siliceous shaly rocks with sparce carbonate interlayers. The carbonate interlayers that are potential reservoirs have been exposed to secondary transformations. It has proved challenging to estimate the reserves in the Abalak formation using the historical well logging suite because of the complex mineral composition that exists in this formation. New core data and a more extensive well logging suite in the more recent wells have helped to solve that problem.......
