Optimización de la producción de un Campo Z mediante el uso de análisis nodal y sensibilidades para pozos con problemas en operación de bombas electrosumergibles

Abstract

In the present work a study of the production behavior presented by the electrosumergibles installed in the X platform of the Z field in the Eastern Basin of Ecuador was carried out, in order to obtain this purpose, the Pipesim software was used, which is a technological tool that allows the integrated analysis of the production systems that a field possesses. It began with the collection, organization and review of the information to be used in the development of the work. The steps to be followed for the construction of the well models and production network of the Z field were also described; additionally, sensitivity analysis was carried out for the wells belonging to platform X, showing optimization opportunities such as optimal frequency analysis and redesign of electrosubmersible equipment.

Subsequently, and based on the analysis of optimal frequencies and redesign of electrosubmersible equipment, optimization proposals were made considering the results of the wells and production network models. The optimization proposal called case 1 consists in the management of optimal frequencies and the so-called case 2, consists of the redesign of the electrosubmersible equipment of the wells: X3, X12, X14 and X19 considering the optimal frequency management.

Finally, the economic study of the optimization proposals was carried out, considering only case 2 since this presents the direct intervention of the selected wells for the change of electrosumergible equipment.
