Water/oil cresting in horizontal wells : a sensitivity study

Akangbou, HN; Burby, ML; Nasr, GG

Abstract

This work presents a rigorous sensitivity analysis on cresting using a physical model, to
investigate the effects of varying inclined section of horizontal well, lateral length in
reservoir and oil viscosity on oil recovered, cumulative of water produced and Water
Cut in thick- and thin-oil rim homogeneous reservoirs faced with strong bottom aquifer
and considerable gas cap. From the results, it was observed that the geometry of the
horizontal well and location of the bottom water injection points significantly influence
the cumulative liquid produced, particularly in thin-oil rim reservoirs. The cumulative
water produced and cumulative Water Cut were found to increase with increase in oil
viscosity. The oil recovered from the thin-oil rim reservoir, were as high as 17.84% and
24.92% for oil viscosity of 50 cP and 100 cP respectively whereas 19.15% and 13.93%
were observed for cumulative water produced from the thick-oil rim reservoir at 50 cP
and 100 cP respectively.
