World demand for oil has been steadily increasing, currently at the rate of about 1.5% per year, and it is estimated
to reach 100 MMSTB/day by 2014. In terms of global oil supply, there is about 3.2 trillion barrels of recoverable
oil amenable to conventional and advanced technical recovery schemes. One trillion barrels of this amount has
already been produced and consumed as of 2004 and the remaining 2.2 trillion barrels remains to be produced and
it represent a significant opportunity for secondary or tertiary EOR recovery processes.
Gas injection has been used successfully in both oil and gas-condensate reservoirs. Hydrocarbon recoveries have
increased over what could be obtained by primary drive mechanisms and waterflooding. It is recognized that the
phase and volumetric behavior of gas/oil systems during gas injection has an important effect on recovery efficiency.
Fluid properties influence all three components of recovery efficiency.
Core Laboratories offer an extensive range of EOR services to enable operating companies understand the phase
behavior and problems associated with miscible and immiscible gas injection processes.
