Gas-assisted Gravity Drainage (GAGD) Process for Improved Oil Recovery

詳細技術說明: The Gas-Assisted-Gravity Drainage (GAGD) process rapidly and inexpensively recovers large amounts of oil trapped in reservoirs after primary recovery and secondary waterflood techniques. More than 60 percent of the original-oil-in-place (OOIP) remains unrecovered in America’s oilfields after the application of primary and secondary oil recovery technologies. This amounts to 407 billion barrels of trapped oil in onshore reservoirs alone within the US. The GAGD process has shown recovery rates of 65 to 90 percent of the stranded oil.

*Abstract: The GAGD process places one or more horizontal producer wells near the bottom of a payzone of a subterranean reservoir and injects a fluid displacer, such as carbon dioxide, through one or more vertical wells or horizontal wells. As the fluid displacer is injected into the top portion of the reservoir, it forms a gas zone that displaces oil and water downward toward the horizontal producer wells. This process can be modified to be used in a single well making it useful in offshore formations.
