Conventional Reservoirs

  1. Special Core Analysis (SCAL) – Rock Matrix: Steady-state measurements of two- and three-phase relative permeabilities using reservoir live/dead fluids under reservoir pressure and temperature conditions (in situ characterization of saturation using x-ray imaging technique)
  2. Special Core Analysis (SCAL) – Fracture: Steady-state measurements of two- and three-phase relative permeabilities in fractures
  3. Routine Core Analysis (RCAL): Porosity, permeability, permeability degradation, fluid content, mineralogy, etc.
  4. Enhanced Oil Recovery (EOR) studies for conventional reservoirs (e.g., foam-assisted hydrocarbon/CO2 gas injection, chemical (ASP) flooding, miscible and immiscible gas injection, WAG, low-salinity and engineered waterflooding, complex non-Newtonian fluids, nanoparticles, etc.) using live reservoir fluids and under reservoir pressure and temperature conditions
