Title: METHOD OF IMPROVING MOBILITY OF HEAVY CRUDE OILS IN SUBTERRANEAN RESERVOIRS
Abstract:
A method for improving mobility of heavy crude oil in a subterranean reservoir is provided. A fluid formulation can be introduced into the reservoir, the fluid formulation comprising water and a surfactant, and optional co-solvents. The fluid formulation can produce one or more of a dispersion and an emulsion in the reservoir, whereby the surfactant acts as an dispersant or emulsifying agent, emulsifier and/or drag reducing agent. The emulsion or the dispersion can have a water external phase and a crude oil internal phase.
