ENHANCED OIL RECOVERY (eor)

The past and ongoing research into enhanced oil recovery (EOR) can be roughly divided into four general areas:

—Gas injection, including CO2, N2, NGL, flue

—Chemical, including
surfactant, surfactant with polymer, surfactant with foam

—Thermal, including convention steam, steam assisted gravity drainage, cyclic injection, and in-situ combustion

—Conformance and related| issues. 

Each area has its own history, potential, technology, opportunities and obstacles. The obstacles can be categorized as technical, economic, and legal/regulatory. Each area is needed to maximize the production potential of the domestic fields. The “prize” is quite large, however. According to the U.S. Department of Energy (DOE), 175 billion barrels have been produced in the U.S. (excluding the deep and ultra-deep water Gulf of Mexico. However, from those same fields 400 billion barrels are “stranded” after traditional primary and secondary oil recovery. This compares to an estimated 21 billion barrels of proven reserves, so the opportunities are enormous.

Proposed International Study of Chemical Flooding EOR

IFP Energies nouvelles of France announced on March 17 the completion of a preliminary study with Petrobras and Statoil to better understand chemical EOR's impact on surface water treatment facilities. The preliminary study analyzed fluid separation technologies, viscosifiers and surfactants, and treatment of produced water for reinjection into reservoirs for chemical EOR. The study will continue as the three-year Dolphin research program with IFPEN partnered with IFP Technologies Canada, OMV, Shell and Wintershall. The Dolphin project will assess representative oil fields for chemical EOR potential.
