A Parametric study of water-coning in horizontal wells

Abstract

The present work is related to water cresting in horizontal wells. A critical rate estimation method based on the observation of the water/oil interface is suggested. For this purpose, a prototype reservoir is simulated numerically to monitor the water/oil interface movement when some relevant parameters are changed. Applying this method, the effect of anisotropy ratio, well length, well position and mobility ratio has been studied and relations between the critical rate and these parameters are presented. The results compare favorably with the work available in the literature.
