EOR/IOR

Shell invested in a Singapore solar company and signed an agreement to purchase a Texas company with solar and other renewable assets. Along with its minority stake in a company that uses solar to generate steam for EOR in the Middle East, Shell catches some rays in the Asia Pacific, US, and Oman.

In a plenary session at the Unconventional Resources Technology Conference, executives in charge of unconventional operations for international oil companies talked about how they have slashed their cost per barrel.

This paper presents an overview of the SACROC Unit’s activity focusing on different carbon dioxide (CO2) injection and water-alternating-gas (WAG) projects that have made the SACROC unit one of the most successful CO2 injection projects in the world.

A critical step in proper design and optimization of any chemical-enhanced-oil-recovery (CEOR) process is appropriate and precise numerical simulations.

This study explores the mechanisms contributing to oil recovery with numerical modeling of experimental work and investigates the effects of various parameters on oil recovery.

Dimethyl-ether (DME) -enhanced waterflood (DEW) is a process in which DME is added to injection water and, upon injection, preferentially partitions into the remaining oil.

High-concentration polymer flooding can improve oil-displacement efficiency but separation of oil/water mixture becomes more difficult because of emulsification. In this work, a case history of dehydration technology for HCPF production and lab investigation of emulsion behaviors are reviewed.

Saudi Aramco saw a jump in production for a type of EOR that often takes years to see full benefits.

Carbon dioxide (CO2)/water foams are of interest for mobility control in CO2 enhanced oil recovery (EOR) and as energized fracture fluids or as hybrid processes that combine aspects of both processes.

This article describes how the use of a biological EOR technique that applied produced water for reservoir flooding in a mature field led to rapid and substantial increases in oil production.
