Fluid Mixing

Miscible Mixing can take any two end‐member fluids and mix them according to their responses to convection, diffusion and dispersion. The fluids are assumed to be miscible, but may be compressible. Applications include the mixing of two distinct oils, querying gravity segregation and convection drive during reservoir filling and injecting CO2 into saline aquifers.

The n-Component Mixing module extends this functionality with multi-phase capabilities.

These simulators are being linked with Migration simulators to provide an advanced workflow for conducting detailed reservoir filling studies that consider charge rates, composition and associated mixing at the reservoir conditions.

Reservoir fluid mixing applications

  • Reservoir fluid continuity assessments
    Model fluid mixing to establish the likelihood of reservoir compartmentalization for appraisal and development projects.
  • Charge history and fluid alteration evaluations
    Use Permedia™ Suite software to integrate basin-scale and reservoir-scale processes for prediction of the distribution and quality of fluids within reservoirs.
  • Predict non-hydrocarbon gas distribution
    Estimate time scales for mixing of non-hydrocarbon (e.g., CO2) and hydrocarbon gases in a reservoir to predict distribution and evaluate controls.
  • Geochemical surveillance studies
    Create detailed fluid distribution models and use these to model time-varying attributes of produced fluids in production settings.

Forced convection, with gravity, with diffusion, with dispersion

Component concentrations modeled using Permedia's fluid mixing simulator using the SPE Comparative Solutions Project, Model 2, which consists of 1.2 million gridcells. Fluid movement is governed by diffusion and dispersion and there is an applied pressure gradient between the component concentrations through time.
