Geology, Geophysics and Development of Oil and Gas Fields

The subject of this article is to review the innovative potential of the oil and gas smart technologies developed in Russia and abroad during 2010–2015. Opportunities and prospects for the use of the smart key oil and gas technologies are briefly described. Most of the undeveloped resources of Russia are located in the Eastern Siberia, the Far East and the Arctic regions. Creation of smart oil and gas complexes (mini-clusters or mini industrial hubs) will significantly reduce the capital costs and oil production self-costs. Innovation potential of smart Russian and foreign oil and gas technologies is analyzed. New breakthrough technologies in the field of geology, drilling, development and operation of smart oil and gas fields are identified. The experience of the creation of smart oil and gas technologies in Russia and abroad is summarized.

Key words: innovative potential; smart industrial complex; smart oil and gas complex; mini industrial hubs; mini-clusters; smart oil and gas technologies; smart development and operation of smart oil and gas fields; scientific and technical revolution (STR); exploration of the World Ocean; smart oil and gas fields; real-time mode.

Results of the rock samples study (outcrop, mine development, well) confirm the field data of the regular changes of the rocks reservoir properties and wells productivity as they move away from the faults. In this direction fractures density per a volume unit of a productive formation reduces while porosity increases. Along the direction of shock waves propagation and seismic waves vibration, collectors’ types and formations’ productive series are generated in the respective zones of rocks compaction. Optimal combination of cracks and pores is achieved in the second zone of rock compaction (porous-fractured and fracture-porous type of reservoirs), thus ensuring wells stable operation and maximum coefficient of oil recover (COR) in the considered site of YuV₁¹ formation of Vategansky field. The detailed study of the revealed regularities proved crucial role of faults in formation of rocks’ normal-fault zoning and the dependence of wells productivity on their location in the specified zoning. The universal model of a reservoir permeability and porosity makes it possible to differentiate the developed areas by the rocks compaction zones, by rocks fracturing intensity, by types of collectors and wells productivity, thus allowing justification of measures aimed at sound management of the development of those parts of a field that are complicated by faults.

Key words: normal-fault zoning; vertical cracks; reservoir pressure; faults; well productivity; rates of oil withdrawal; coefficient of oil recover (COR); oil production rate.

One of the most common ways of reproduction of and hydrocarbon reserves and resources for oil companies is the acquisition of new sites from the state unallocated subsoil reserve fund. Governmental bodies often publish extensive lists of sites for licensing that contain hundreds of subsoil sites from which you have to identify the most promising ones for a full assessment. Current methodologies applied nowadays for assessing the sites are labor-intensive and can’t be applicable for the purposes of the preliminary assessment (the rapid assessment). The paper presents the mathematical models built to assess the prospects for the acquisition of oil sites of subsoil using the information on sites of the Perm region.

Key words: undistributed fund of subsoil; resource base; oil reserves and resources; promising exploration areas; forecast; regression equations; correlation; informative value; statistical analysis.
