Principals and Application of SCAL Data for Heavy Oil Reservoirs Reservoir Descriptions and DynamicsManagement and Information


Shawket Ghedan, Anjani Kumar

Description

The impact of Special Core Analysis, SCAL, data on the way fluids are distributed in conventional reservoirs, their hydrocarbons initially in place as well as its subsequent estimation of reserves are well researched and studied and understood, and under different conditions of depletion, secondary and tertiary EOR-Chemical, -Solvent flooding processes. This course will concentrate on the principals of SCAL for heavy oil reservoir under the effect of thermal recovery processes. It will explain the impact that SCAL data would have on the estimation of the oil reserves, and the management of these reserves. This course will show how SCAL data would be altered as a function of reservoirs wettability change under thermal recovery processes. The course also explains the idea of reservoir saturation history and the associated hysteresis with steam and hot water injection, especially those happening in the steam chambers. This course will show the implementation of wettability alteration, temperature, composition dependent and interpolation between relative permeability curves for processes related to heavy oil modeling. 

  • Topics Include: 
    Introduction of the concepts of the different elements of SCAL data, including:
    • Reservoir wettability,
    • W/O and G/O Capillary Pressure
    • Two Phase, W/O and G/O Relative Permeability 
    • Three Phase Relative Permeability
  • Capillary gravity initialization of simulation model under complete water wetting conditions
  • Consider cases of water heavier than bitumen and cases of bitumen heavier than water 
  • Effect of temperature on reservoir wettability 
  • Effect of wettability and temperature change on saturation endpoints 
  • Interpolation between sets of relative permeability curves for different wettability conditions
