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 |
-
Using available field data, geological setting,
and laboratory data, construct
virtual rock samples
|
-
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... |
-
Generate
porosity-permeability trends for the rock types of
interest
