Abstract

The late stage of field development is characterized by reserves depletion; therefore, achievability of ultimate recovery becomes a topical issue. Generally, oil recovery efficiency is estimated for the entire field without due regard for geologic aspects and deposition environment. To enhance the development system efficiency it is necessary to know the achievable rate of oil recovery. Based on actual tendencies, ultimate recovery achievability is analyzed using analytical calculations and a reservoir simulation model which relies on the detailed study of reservoir rock formation process. The required actions and their scope are defined.

    Key words:

    facies, sweep efficiency, compartmentalization, well spacing, reserve recovery, production rate
