Alternativas de intervención para incrementar la producción de pozos de gas del campo Amistad

Abstract

In this project, we model and design an alternative that improves the production of natural gas in the Amistad field in Ecuador. We consider the historical records and production profiles, completion works, reservoir pressure and the existing surface offshore facilities. Currently the pressure drop of flowing bottom in wells F, G and I is enhanced by the completion with gravel pack; this configuration and advancing water in the bottom created the effect of liquid hold up in the tubing reducing production. To address this problem we propose: cleaning of meshes with control fluid and/or acid and the lightening of the hydrostatic column by nitrogen injection with coiled tubing unit. It is also necessary that the production of gas is admitted into the flow line (pipeline), by the installation of a reciprocating compressor. We perform a technical analysis of each of the proposed alternatives taking into account similar works done in nearby wells. Finally, we analyze the economic viability of the different options.
