Increasing efficiency of hydrocarbon fields development based on complex geomechanical research

UDK: 622.276.1/.4
DOI: 10.24887/0028-2448-2019-3-66-69
Key words: rock formation, rock mechanics, stress-strain state, anisotropy of elastic and strength properties
Authors: Yu.A. Kashnikov (Perm National Research Polytechnic University, RF, Perm), S.G. Ashikhmin (Perm National Research Polytechnic University, RF, Perm), D.V. Shustov (Perm National Research Polytechnic University, RF, Perm), S.Yu. Yakimov (Perm National Research Polytechnic University, RF, Perm), A.E. Kukhtinskii (Perm National Research Polytechnic University, RF, Perm)

Currently, solving the problems of increasing the efficiency of hydrocarbon field development is impossible without widespread introduction of rock mechanics at all stages of field development: from designing and drilling wells to optimizing the location of wells in the field and optimizing pressure maintenance system and methods of bottomhole zone treatment. Until recently, geomechanical studies in Russia were conducted mainly by foreign service companies (Schlumberger, Halliburton etc.). However, presently domestic companies create geomechanical centers which primarily carry out applied research. At the same time, geomechanical centers are created in leading universities that solve both fundamental scientific problems and carry out applied research by request of oil and gas industry. One of such centers, oriented on increasing efficiency of hydrocarbon field development, is created in Perm National Research Polytechnic University. The main areas of work of the Center are rock mechanical properties tests; calculating stress-strain state for development of hydrocarbon fields and solid mineral deposits; creating geological geomechanical models of hydrocarbon fields; wellbore stability and deformation analysis for oil and gas wells; development of theoretical and practical basics of oriented hydraulic fracturing; instrumental surveys of displacement of rock and earth surface, including GNSS and InSAR technologies and design of geodynamic monitoring systems.
