Abstract: The invention relates to the correlating of mechanical and geological (e.g. compositional) information from a rock core or a large number of rock cores. A geological facies model may be created correlating mechanical and geological information, and allowing prediction of the mechanical properties of rock with given geological properties, such as composition, porosity, etc.

Abstract: The invention relates to the calculation of parameters to inform hydraulic stimulation of non-conventional hydrocarbon-bearing rock formations, such as shales. Unlike conventional formations, non-conventional formations tend to display elastic-plastic behavior and have stress-strain characteristics which with substantial non-linear regions. A parameter which has been termed Elastic Index (EI) is proposed, together with a demonstration of how this parameter, when coupled with principles of fracture mechanics, may be used to extract meaningful calculated or estimated values for e.g.; total required volume of fracturing fluid; treating pressure; fracturing fluid viscosity; proppant size; and proppant concentration.

Abstract: The invention relates to the dividing up and testing of bulk samples from cores of rock. The method involves the extraction of several plugs for triaxial testing which are derived from exactly the same level in the core, and also Brazilian test samples and samples for compositional and textural analysis from the same level. Triaxial tests with different confining pressures may be performed to destruction on separate triaxial plugs, allowing a reliable full Mohr-Coulomb analysis to be performed. Mechanical properties may be related more reliably to composition and texture of rock. The technique is especially useful for non-conventional rock such as shale.
