Analytical feasibility of the application of improved petroleum recovery, case study Ecuador

Abstract

Improving the recovery factor is sufficient motivation for any company to include in its planning, a feasibility study to set up the improved recovery technology, also known as EOR, for its acronym. This method consists in injecting miscible fluid, to favorably alter the rock-fluid conditions and to move the hydrocarbon to the producing wells, giving rise to a complex dynamics in the reservoir. From the information obtained in the field, such as: PVT data, production history, recovery factor, correlations, well geometry and together with the selection criteria demanded by this technology, we can proceed to design an injection model miscible, deepen the simulation of the site and obtain predictions not so far removed from reality.

EOR is one of the technologies that takes advantage of the unproductive wells in good condition and can be injected into the reservoir more than 16 fluids to provide a sweeping effect that optimizes production, however apply one of these selected EOR methods, can be expensive in the industry, for this reason the present study allows to determine the best option to implement one of these techniques and to guarantee an effective return of investment and an adequate use of capital, which presents a challenge to engineering.
