Today’s fast-paced market requires quick results and accurate data to make reliable hydrocarbon decisions in a timely manner. The GeoMark PVT Laboratory performs a full range of pressure-volume-temperature (PVT) studies, oil-based mud evaluations, and flow assurance screening with rapid turnaround. High-resolution compositional analysis is often combined with isotopic measurements to deliver extremely detailed communication studies.
GeoMark Research’s established PVT laboratory has been serving the industry for over 15 years, providing critical subsurface fluid insights for our global customers:
Once received in our laboratory, the collected fluid samples are restored via agitation at the original reservoir pressure and temperature. Initial validation checks provide basic PVT properties and a measure of oil-based mud contamination common to open-hole samples. More in-depth analyses provide additional information about specific hydrocarbon behaviors.
Samples of gas and liquid exiting the separator are acquired, along with separate flow rate measurements of each, providing the gas-oil ratio (GOR). The fluids are then recombined in the laboratory to recreate representative reservoir fluids for accurate analysis.
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.
