Gryshanenko V. Methods for evaluating the efficiency and criteria of the improvement of oilfield development systems

The thesis is devoted to methods and criteria for evaluating the current technological efficiency of the realized oilfield development systems. We have proposed a new principle of evaluating the technological efficiency, which consists, of comparison of the actual and potential values of efficiency criteria. The influence of geological and technological indices on the efficiency criteria of development systems has been studied and improvement of fields development of Dnipro-Donets'k depression is studied. Methods and software for evaluating the technological efficiency of oil and gas fields development systems has been developed. Using the proposed methods, we have evaluated the technological efficiency of the realized development systems of fields of the Dnipro-Donets'k depression and formulated recommendations for their improvement.
