QUANTITATIVE ANALYSIS OF WELL PRODUCTION BY POETTMANN AND CARPENTER CORRELATION AND CHOICE OF AN ACTIVATION MODE. CASE OF THE KINKASI-C1 WELL IN THE KINKASI FIELD

Abstract

With a strong focus on optimizing the performance of a producing well, our work performs a nodal analysis of the subsurface production subsystem. Using data from the Kinkasi-C1 well on the Kinkasi field, producing in the Vermelha, it analyses the elements of this subsystem, focusing on the analysis of head losses in the production tubing. Knowing the daily production rate and having determined the inflow performance relationship (reservoir pressure and physical properties of the fluids), the wellhead pressure that was lacking was determined. Starting from the pressure node at the bottom of the well, the Poettmann & Carpenter correlation provided us with the head losses along the tubing and, in turn, the wellhead pressure for the company's daily flow rate. Given that this correlation requires tedious calculations, we used Java programming to develop software to support its calculation algorithm. After this stage, the possibility of producing more with or without activation was studied. By prioritizing oil production, activation by pumping, more specifically using an ESP, was the appropriate means of optimizing KK-C1's performance.
