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.

Biological EOR Process to Recover 20% More Oil

Glori Energy Inc. has received a patent on their technology to use natural biological processes to recover an additional 20% of reservoir oil. The Patent was issued on Sept 9, 2014. The process is called Activated Environment for the Recovery of Oil (AERO). Chief Technology Officer for Houston based Glori, Dr. Michael Pavia said, "Glori is pleased to have been granted this key AERO technology patent from the U.S. Patent and Trade Office. Leveraging more than 25 years of Statoil research and Glori's IP advancements, we have worked closely with our co-inventors to develop what Glori believes to be the most advanced method for increasing the amount of oil that can be recovered from conventional oil reservoirs." The AERO system incorporates biotechnology work based on two decades of work in the field in the U.S., Canada, Austria and Norway.
