Factor analysis of the success of well interventions as a tool for improving the quality of geological and simulation models

Abstract

The paper compares various methodological approaches for factor analysis of the success of well interventions. Particular attention is paid to the factor analysis of the drilling results of multi-stage fractured horizontal wells. Improved analysis tools based on the integral method and the use of a regression model are proposed. Correct consideration of all technological factors at the planning stage of well interventions makes it possible to avoid overestimating or underestimating the potential of new drilling. The use of the considered tools for a number of new pads allowed us to systematically correct geological and simulation models, correctly estimate the potential of new wells and make timely decisions regarding the need for engineering operations and future drilling.
