Approaches to non-stationary water-flooding substantiation on the example of the deposits of "Povkhneftegaz" Territorial Production Department (TPD)
The paper considers the approaches to the effective planning of non-stationary water-flooding (NSWF) on the example of the fields of "Povkhneftegaz" Territorial Production Department. It is shown that the pressure drop curves and the Hall plots can be used to estimate the state of the bottom-hole zone of injection wells. This allows to timely carry out the necessary measures to prepare wells for the effective implementation of non-stationary water-flooding and to reduce the risks of ineffective injection. In further, when developing a program of non-stationary water-flooding, it is proposed to use the discussed approaches to improvement of the efficiency of non-stationary water-flooding (NSWF).
