Standard enhanced oil recovery (EOR) and PVT testing programs include experiments, such as solubility/swelling, multi-contact, slim tube, vapor-liquid equilibrium (VLE), and fluid property measurements.
These tests are designed to determine the extent of gas miscibility and mixture phase behavior during gas injection into hydrocarbon reservoirs. While common in conventional reservoirs for decades, EOR programs have also found recent applicability in unconventional plays.
Surface oil and gas samples are captured and recombined to recreate downhole reservoir fluids. Injection gases may be separator or sales gas derived from a nearby installation, or synthetically prepared gas based on a composition provided to our laboratory.
