The laboratory studies described here in detail were conducted to ascertain the properties of oil-in-water emulsions and to determine if such emulsions could act as a selective plugging agent to improve oil recovery in waterfloods.

Introduction

In waterfloods, the rapid channeling of water from injection to producing wells through the more permeable portions of the reservoir gives low oil permeable portions of the reservoir gives low oil recovery. A number of materials, such as cement, ground leather, and ground limestone, have been used in wellbore treatments to improve injection profiles in water-injection wells, However, even if such treatments do effect a better distribution of water in the formation at the wellbore, they are unlikely to be successful because of cross-formation flow near the wellbore. A deep-penetration method should be more effective. Silica gel, rubber latex, and asphalt, have been tested as deeper-penetration plugging agents in attempts to decrease reservoir heterogeneity. The laboratory investigations described here were undertaken to determine the properties of oil-in-water emulsions and to study the flow of emulsions through porous media. Samples of core material can be considered as miniature reservoirs and the cores are heterogeneous. In our investigations we hoped to determine if oil-in-water emulsions would decrease reservoir (core) heterogeneity and improve water displacement of oil in sandstone reservoirs.
