Estudio para incrementar la producción aplicando el método de Petrie, Smart y Wilson (PSW) en el Campo Mariann Norte del Bloque 62 del oriente Ecuatoriano

Abstract

The Mariann field was discovered in the year 1970, being one of the oldest oil areas in Ecuador. It is located in the Tarapoa Block in the Ecuadorian Oriente of Sucumbíos province. Due to pressure depletion in the field over time leading to a decrease in production, this study will evaluate operational parameters to either change the pump or redesign it. Hydraulic jet pumping can be used throughout the well's productive life. For the project development, five wells that have experienced production decline were selected. This thesis presents an overview of the Mariann field's characteristics, as well as the theoretical foundations of hydraulic jet pumping, the pump components, and its operation. The second section describes the methodology used, applying the method proposed by Petrie, Smart, and Wilson (PSW). Corresponding calculations were conducted for each of the selected wells to optimize production and perform nodal analysis for each well. The third section provides a detailed technical analysis of the results obtained using the PSW method. Additionally, to determine the method's feasibility, the economic analysis considers crude oil prices in three different scenarios. The conclusions and recommendations of this thesis are also presented.
