Análisis técnico de la recuperación secundaria en reservorios de crudo pesado (Basal Tena) del campo Atacapi

Abstract

The present work was developed with the objective of analyzing the impact that the production has had on the Basal Tena sandstone formation in the northern Atacapi field due to the waterflooding project implemented for secondary recovery (March 2015), formed by an injector well and a producing well.

With Petroleum Experts’ software, MBAL, the material balance was made, and streamlines were represented with different injection and production cases. In addition to that, the continuity of Basal Tena between Atacapi-26D and Atacapi-29 was proved through with pressure, water cut and salinity analysis.

A base case was developed representing the reality of the reservoir, and from this, tree additional cases where was considered loss of injection, addition of an injector and producing wells, and addition of an injector well and two producing wells to the current model.

The best alternative for production increase was the one with greater recovery factor and consequently a greater cumulative oil, proving the effectivity of water injection in this reservoir.
