Estudio para la optimización de producción de pozos con bombeo electrosumergible, mediante análisis nodal del campo Cuyabeno

Abstract

Optimization proposals are made to increase the production of the Cuyabeno Field for which a nodal analysis is performed. Prior to the nodal analysis a selection (Initial Filter) is performed, the criterion used is the selection of high (> 500 BPPD) and low (<200 BPPD) wells. The selected wells are 22, of which the nodal analysis is performed with the current operational data, obtaining the production that each well should theoretically have. To the results of the nodal analysis a final selection (Final Filter) is applied, which is based on analyzing them with PIP data, frequency, higher efficiency range of the installed BES, thus obtaining the selected wells to perform the optimization. The wells selected are 8, of which one well is being produced in upthrust, and 7 wells are produced in downthrust. Optimization proposals are developed based on a comprehensive study of petrophysics, lithology, W.O's summaries, production and PIP records, cement logs. The optimization proposals are summarized in works of: frequency increase, upsizing, matrix stimulation, changes of productivity zones, and a change of completion. Finally, an economic feasibility study is carried out.
