Abstract

A new CRM-modeling-based approach to identification of performance parameters for reservoir pressure maintenance systems is proposed to meet the challenges associated with the analysis of waterflood patterns for mature field development. This approach relies on approximation of well interference based on field data on production rates, well injectivities and bottomhole pressures. Due to relative simplicity of this approach, history matching is not time consuming and ensures adequate accuracy of the forecasts.

The proposed CRM-modeling-based method for analysis of waterflood performance comprises evaluation of unproductive injection and performance of injection wells, estimation of current injection ratio by grid blocks and individual production wells.

Key words:

waterflood pattern, formation pressure maintenance, CRM, well interference, unproductive injection, injection ratio, daily oil production rate, impermeable barrier
