EVALUATION OF GEOLOGICAL AND ENGINEERING ACTIVITIES IN OIL PRODUCTION
The article is devoted to the problem of evaluation improvement of geological and engineering activities in the process of oil and gas field development. The author argues the differences between geological and engineering activities and well remedial work. The research proves the aim, methods and alternatives to achieve the positive effect. The analysis of the approaches indicates different interpretations, disadvantages, which lead to quite opposite results not only in terms of quality but of quantity. The author suggests maintaining accounting and appraisal of every geological and engineering activity at the specified field assigning a separate investment project to it. On the basis of the fact, that at the beginning of design period all wells have different funds, the investment projects should be divided into three groups. The author suggests using the following succession: firstly, to define the base quantity of production, then to compare it with the possible increase of similar field. It is necessary to point out that it is important to compare the economic result to possible ecological damage.
