PVT Laboratory

Mercury-Free PVT Laboratory FESCO PVT lab technicians and engineering staff provide a complete suite of standard PVT fluid studies and field sampling services. PVT fluid studies can be performed on recombined surface separator samples or subsurface reservoir samples. All reservoir fluid studies include sample conditioning, sample quality checks, sample compositional analysis, physical sample recombination of surface samples to the produced GOR or a specified saturation pressure and temperature (if applicable), and saturation pressure (dew point (DP) or bubble point (BP)) determination at reservoir temperature via Constant Composition Expansion (CCE).


All black and volatile oil studies include measured oil viscosity and separator tests on the reservoir fluid. Black oil studies additionally include a Differential Liberation test to model production below the BP pressure. Volatile oil and retrograde gas studies additionally include a Constant Volume Depletion test to model production below the saturation pressure (BP or DP).


FESCO laboratory and production testing personnel are fully trained to catch all surface samples required for PVT study. FESCO also offers single-phase subsurface sampling services for fluids up to 15000 psi and 350 F and well site transfer of collected samples to transfer cylinders at reservoir temperature.
