Operators are required by ERCB to provide data on the compressive strength of their caprock shales to address the integrity concerns. Geomaterials are generally friction-controlled. Therefore, their compressive strength depends on the prevailing stress condition. Two parameters are used to define such dependence: friction angle and cohesion. Geomechanical laboratory tests are used to measure these two strength parameters. High-quality cores representative of the in-situ condition are needed. Proper core preservation and transport is fundamentally important for the caprock shales. Moreover, the prevailing stress condition must be calculated from the operating pressure and temperature conditions. Geomechanical simulation is thus needed.
With integrated field, laboratory and simulation capabilities, BitCan is the one-stop source for your needs in studying the compressive strength. Our laboratory tests can closely simulate the field conditions. Our on-site shale preservation and transport system ensures high-quality cores used for the laboratory tests. Our simulation is cost-effective, capturing the key physics while properly simplifying the complex field processes.
