Application of non-parametric criteria when analyzing processes of oil fields development
To determine trends of progress of development of the development process and timely decision-making on oil production control there developed an approach to the analysis of the water impact on the basis of the Gini coefficient. The essence of this approach lies in the joint analysis of the dynamics of Gini coefficient change, oil withdrawal and water injection as well as water flooding of wells’ production to assess the effectiveness of the water effect on a deposit and timely decision-making on the regulation of the “withdrawal-injection” system. Gini coefficient application along with other methods of analysis of oil fields development process allows making justified decisions to change the development strategy in the context of information insufficiency and to make a timely decision on oil production control and regulation of operational modes of production and injection wells.
