HPHT PVT Studies

Physical property and phase behavior PVT data provide the necessary information to properly manage reservoir production. Initial measurements of fluid compressibility and shrinkage factors are required to

  • determine oil in place and gas in place
  • provide input for recovery estimates
  • evaluate reservoir material balance calculations.

Understanding fluid behavior in the reservoir requires viscosity, constant composition expansion, and differential liberation or constant volume depletion measurements. Fluid behavior influences both recovery and costs. Compositional analysis and the physically measured fluid properties are used as input and the basis for tuning EOS modeling software. This complete dataset can then be used to

  • understand the phase behavior
  • evaluate various production scenarios
  • optimize reservoir production and oil recovery schemes
  • maximize ultimate recovery
  • optimize production economics.

Separation tests simulate the gas and liquid separation of a reservoir fluid at the surface conditions. Results generated include gas/oil ratio for each separator stage, liquid shrinkage factor, and evolved gas properties at each stage. These data are often used in an EOS simulator to optimize separator conditions for maximization of oil production.
