PROXY MODEL FOR HYDROCARBON RECOVERY IN A SEVEN-SPOT WATERFLOODED WELL PATTERN

Abstract

This article is about establishing an artificial modeling environment using real data, then creating special formulae in order to estimate the recovery factor of the depletion of the reservoir model. The key concept is that these aids in the form of formulae can be very useful, economic and fast methods to help reservoir simulation. Waterflooding was examined in previous years and a sensitivity analysis was conducted several times. First the parameters were screened for impact and importance, then the structure of the resulting proxy model was chosen, along with the accuracy, both based on the focus of investigation itself, which is the recovery factor. The artificial reservoir environment is a seven-spot  water flooded well pattern in an initially undersaturated oil reservoir. The results in this particular study are three formulae which are capable of predicting the recovery factor with a satisfactory error margin after five, ten, and fifteen years of production as a function of the initial produced fluid rate target.
