Reservoir Fluid Section consists of two main laboratories (PVT and EOR laboratories) which are managed and staffed by highly trained and experienced personnel operating under strict safety and quality guidelines.
Routine PVT Studies normally cover the following laboratory tests :
Black oil PVT studies
- Rigorous validity assessment of submitted downhole or surface samples.
- Selection of the most suitable sample(s) for PVT study.
- Reservoir fluid composition.
- Physical recombination (if separator samples).
- Constant Composition Expansion (CCE).
- Differential Liberation (DL).
- Viscosity measurements.
- Separator tests.
Gas Condensate PVT studies
- Constant Composition Expansion (CCE)
- Constant Volume Depletion (CVD)
- it is important to carry out the validation of the samples before performing the reservoir study.
- The validation process depends on the type of sample collected, i.e. whether they are bottom hole, wellhead or separator samples.
- Minimum Miscibility Pressure (MMP)
- Minimum Miscibility Composition (MMC)
- Swelling tests single contact gas injection
- Determination of mixture saturation pressure and volume
In this laboratory, specialists perform the following tests :
- Evaluation of Mud Properties
- Evaluation of Bentonites.
- Evaluation of drilling fluid additives.
- Capillary and Electrical Properties at OBP
- Rock Mechanics System (RTR-1000)
- Resistivity Index by Continuous Injection
- Linear X-Ray Scanning System (LXRS-400)
- Nuclear Magnetic Resonance (NMR Coring)
- HPHT Filter Press
