This paper reviews the production optimization strategy of an artificial lift system that has been implemented in a carbonate reservoir in an Abu Dhabi onshore field. The adapted optimization technique assures the mitigation of the main challenges related to reservoir heterogeneities, in addition to completion design which has a significant impact on ESPs sizing, operation and optimization processes.
An integration approach of reservoir dynamic data and ESP performance was established as a guideline for ESP surveillance, diagnostic and targeting candidate for production optimization by implementing at least one of the possible solutions: (a) upgrading ESP-surface equipment, (b) anticipate WO for re-sizing & ESP Deeping jobs, (c) well design strategy review.
The result of this effort demonstrates the successful implementing of proposed solutions by enhancing the oil production by more than 20% in all separates pilot tests conducted in the field. The project success can lead the way forward for future ESP application in similar harsh down hole conditions.
