Improving the efficiency of exploration and development of oil and gas fields in the conditions of frequently interbedding rocks

et al. 2022

Exploration and development of mineral deposits largely affects the dynamics of development of the oil and gas industry in the country. An important stage in the field development is the design of technologies for constructing wells, and the drilling process itself. The appropriate modes and drilling tools create conditions for the maximum oil recovery. In this paper, based on the analysis of existing well drilling technologies and features of the mining and geological conditions of the fields, the use of a new technological solution is substantiated and recommendations are given for its implementation in the Yuzhno-Priobskoye field. The feature of the Yuzhno-Priobskoye field is frequent interbedding, that is, alternation of some rock layers by others. These layers exhibit different mechanical properties, such as hardness, elasticity, and abrasiveness, which arise certain difficulties in the field exploration and development. The proposed technological solution significantly increases the efficiency of mining and geological operations.

“…The development of deposits in carbonate reservoirs shows that in some cases, in some areas, catastrophic water breakthrough into reservoirs occurs through fracture systems and individual highpermeability interlayers, which does not always have a favorable effect on technical and economic indicators [1][2][3][4][5][6][7][8]. The vast majority of these cases are due to high discharge pressures.…”

Differentiation of exploration and production wells to prevent the breakthrough of water injected into the reservoir

Mukhametshin

2022

The equations of canonical discriminant functions and distributions were derived for deposits of the Tournaisian age of the Volga-Ural oil and gas province. This enables solution to the problems of increasing the efficiency of implementation of various contour waterflood systems, choosing exploration and production wells for focal waterflood, and estimation of the well grid density at the stage of preparation of the design documents, pressure and injection volumes, as well as making scientifically grounded management decisions for regulating the exploitation process. The method has been proposed to prevent a catastrophic breakthrough of water injected into the reservoir, which is the reason for a significant decrease in the degree of oil reserves recovery.
