Petroleum Oil Reservoir- Fluid Properties

Outline: Petroleum Oil Reservoir - Fluid Properties

I. Introduction to Reservoir Fluids
- Types of Fluids: Hydrocarbons (Oil & Gas) and Water (Brine).
- Fluid Classification (Based on Phase Behavior):
  - Black Oil vs. Volatile Oil.
  - Retrograde Condensate, Wet Gas, Dry Gas.
- Phase Behavior Fundamentals:
  - Pressure-Temperature (P-T) Diagrams.
  - Bubble Point Pressure, Dew Point Pressure
  - Critical Point.
II. Chemical Composition
- Hydrocarbon Components: \(C_1, C_2, C_3, ... C_7+\) (Heptanes-plus).
- Non-Hydrocarbon Components: \(N_2, CO_2, H_2S\).
- Asphaltenes and Resins.
III. Physical Properties of Reservoir Oil
- Oil Formation Volume Factor (\(B_{o}\)): Ratio of volume at reservoir conditions to surface conditions
- Solution Gas-Oil Ratio (\(R_{s}\)): Amount of dissolved gas
- Oil Compressibility: Volume change vs. pressure change.
- Oil Viscosity : Internal resistance to flow.
- Oil Density and API Gravity.
IV. Physical Properties of Reservoir Gas
- Gas Formation Volume Factor
- Gas Compressibility Factor
- Gas Density
V. Reservoir Water Properties
- Salinity
- Water Formation Volume Factor
- Water Viscosity
VI. PVT Analysis & Equilibrium
- Sampling Techniques (Bottomhole vs. Surface).
- Laboratory PVT Experiments: Constant Composition Expansion (CCE), Differential Liberation (DL), Separator Test.
- Equations of State (EOS) for modeling.
VII. Fluid Flow & Saturation Effects
- Surface Tension and Capillary Pressure.
- Relative Permeability.
