Summary: The Electronic Core Laboratory is a common software/laboratory platform we use to understand the mechanical, transport, chemical, electrical, and magnetic properties of a sample of permeable rock and the fluids in the pore space of this rock. Using a somewhat different terminology, we strive to formulate a Common Rock-Fluid Model, that will allow specialists from very different disciplines (reservoir engineers, geophysicists, geologists, petrophysicists, geochemists, logging analysts, etc.) to acquire a common understanding of the subsurface rock-fluid systems at different scales. We start from the small, 0.5-10 cm, scale. The rock-fluid systems at this scale can be imaged and otherwise investigated in the laboratory, and modeled in the computer.

Our general procedure is as follows:

Looking down from the ALS onto Berkeley Campus and the Bay

  1. Using available field data, geological setting, and laboratory data, construct
    virtual rock samples
  1. For each sample, calculate its mechanical and fluid transport properties:

- Macroscopic strain-stress curves
- Porosity,
- Anisotropic absolute permeability,
- Process- and rock-dependent capillary pressures and relative permeabilities,
- Formation factor, bulk moduli, NMR responses...

  1. Generate porosity-permeability trends for the rock types of
    interest
