Subjects of research: Jurassic and Upper Paleozoic sediments of Samsk, Kosbulak depressions and the Kassarmin swell.
Purpose of work: specification of features of geological structure and definition of prospects of oil and gas content of the Samsk, Kosbulak depressions and the Kassarmin swell on the basis of generalisation of the new data of geophysical works and deep drilling with attraction of the existing information on adjoining territories for a choice of further directions of oil and gas searche works.
Methods of research: complex analysis, studying and ordering of materials of geologic-geophysical works, deep drilling and laboratory researches of core, and also studying and generalisation of all previous researches. Construction of series of maps, seismogeological sections and schemes.
The results obtained and their novelty: the geological structure of Jurassic and Pre-Jurassic sediments with estimation prospects of oil and gas content on basis of lithologic-facial is specified, structural and geochemical preconditions, within investigated territory are allocated zones, of possible oil and gas content on detection of HC congestions.
Practical value: directions of oil and gas search works on Jurassic and PreJurassic complexes on detection of oil and gas congestions are developed.
Degree of embed and economic effectivity: the developed recommendations on location deep wells will promote detection of oil and gas deposits and gain of HC stocks, and offers on statement of search seismic prospecting CDP-2D works on the allocated sites - to specification of geological structure and preparation of new structures for the subsequent input in deep drilling.
Field of application: at planning and carrying out oil and gas search works in Usturt oil and gas region.
