Abstract:
Methods, compositions, and techniques for enhancing the production of hydrocarbons such as crude oil from subterranean hydrocarbon bearing formations. In some embodiments, the invention relates to processes for evaluating enhanced oil recovery mechanisms in carbonate based reservoirs at both the rock-fluid and oil-water interfaces using spectroscopic and interfacial techniques. In further embodiments, the spectroscopic and interfacial techniques include microscopic, rheometric and tensiometric measurements. In preferred embodiments, the disclosed methods and techniques provide reservoir based details at that allow for optimized “smart water” flooding practices and correspondingly higher oil recovery rates.

Claim (Index 17):
The method of  claim 1 , further comprising the step of:\n introducing a primary oil recovery composition including a brine with at least one component selected from the group consisting of: CO 2 , a chemical solvent, a polymeric, surfactant, and nanoparticles, for recovering the liquid hydrocarbon fraction from a liquid hydrocarbon reservoir formation.
