INCREASING THE ECONOMIC EFFICIENCY OF SHALE OIL EXTRACTION

Based on the joint analysis of changes in the volume and cost of oil production, as well as on the income and profits from hydrocarbons sales, there has been substantiated the economic feasibility of replacing rod pumps by jet pumps in the early stages of exploitation of shale oil deposits. In the course of economic analysis, there has been used the statistical dependence of the oil production reduction, obtained for the Great Bakken oil field, proposed by the author. Using the jet pump allows one to increase profits by selling an additional amount of oil. By studying special points on the graphic dependencies of the change in income from oil sales, the cost of oil production and profit, there are defined the intervals of economic expediency of using certain methods for the development of hydrocarbon deposits. There is also shown the possibility of extending the period of profitable exploitation of the well by using a water jetting method of oil production. A comparative analysis of the economic performance of wells drilling with rod and jet pumps has been conducted.
