Successful ESP Operation ADCO - SHAH FIELD

Abstract

Abstract Artificial lift ESP's were installed in ADCO SHAH Field in the year 1994 to enhance recovery and sustain production. As of September, 2015 Shah Field has a total of 60 oil producers with ESP's, mostly characterized by applications with high water cut and low intake pressures. Additional wells are being drilled to enhance production. High water cut and low intake pressures possessed a challenge, resulting in premature ESP failures thus impacting field performance indicators and cost of work over for ESP replacement. To overcome these challenges ADCO has adopted optimization strategy to enhance oil production in a mature field by understanding the ESP system & reservoir conditions as an integral unit. Shah Field has achieved one of the highest ESP run life of more than 15 years (Well no Sy-32 still running) and 6 more wells operating beyond the MTTF indicator. The objective of this paper is to share ADCO's successful optimization strategy to increase ESP life.
