Neftegeofizika - an integral part of drilling and oil production
The process of oil and gas extraction is absolutely impossible to imagine without exploratory and field geophysics. Its goal is to use the various equipment to understand the physical and chemical characteristics of the section being opened, to relate the obtained parameters to the presence of hydrocarbons in the rocks of this section. Interpretation of the data of well logging allows performing: lithological and stratigraphic dismemberment of the section; separation by the collectors; separation of reservoirs into productive and aquifers, and in productive reservoirs for gas and oil saturated ones; determination of the position of gas-oil, water-oil and gas-water contacts; determination of filtration-capacitance properties: clayiness, porosrty, permeability, gas and oil saturation. To solve these problems, there are many types of geophysical studies of wells - GIS (logging): electrical methods, electromagnetic, radioactive, thermometry, acoustic logging, micro-zoning, etc. Our express questionnaire aims to determine the position of Russian geophysics in Russia and the world, and possible ways of its development.
