Paper Number: SPE-210289-MS
... Abstract Water control in mature heavy-oil reservoirs is a well-known challenge in the Oil & Gas industry. Due to the mobility ratio, water tends to flow much easier compared to oil, leading to premature water breakthrough which pushes water cut values to over 95% or more within weeks...
