Chemical EOR Evaluation

Not all oil fields are chemical EOR candidates and not all chemical EOR processes can be used for all reservoirs. SRC provides initial screening and feasibility studies to determine if chemical flooding techniques are suitable for your reservoir and if so, which techniques are appropriate. 

Fluid-Fluid Analysis — specific measurements include:

  • Water chemistry
  • Interfacial tension
  • Polymer rheology
  • Phase behaviour
  • Wettability/contact angle
  • Static/dynamic adsorption

Coreflood Displacements — micromodel, linear and radial coreflood apparatuses to evaluate varied chemical EOR processes

  • Alkaline-surfactant-polymer flooding
  • Surfactant-polymer flooding
  • Alkaline-polymer flooding
  • Enhanced foam flooding
  • Conformance control/water shut-off
  • Clay stabilization/injectivity improvement

Numerical Simulation:

A finely-tuned black oil model is built according to the measured experimental data. The capillary number increases due to lower oil−water interfacial tension and higher water phase viscosity. As this occurs, different sets of oil-water relative permeability curves need to be specified to history-match the waterflood, chemical injection and theoretical miscible process, respectively.

The chemical injection simulation can also be scaled-up to a field model to provide a better scope for your field operation design.
