Using indirect estimates to improve development efficiency of the deposits with flooding application

Abstract

The article summarizes the experience of two groups of deposits in terrigenous reservoirs of Western Siberia flooding. It is shown that in the presence of various kinds of uncertainties, the problems of deposits flooding efficiency increasing can be successfully solved based on a limited amount of information and indirect data. Algorithms are proposed for predicting the maximum values of cross-correlation functions, reducing the degree of uncertainty in flooding success assessing, predicting the maximum optimal monthly fluid production of wells during the deposits development in the natural regime, as well as wells surrounding injection wells to justify the selective and focal flooding organization, transferring idle wells to the producing-well stock, transferring wells from other horizons. The facilities to which the obtained results, algorithms, models and conclusions can be extended with minimal risks are proposed.
