Method of quantifying static and dynamic rock mechanical properties

A non-transitory computer readable medium (CRM) storing instructions executable by a computer processor, the instructions comprising functionality for:

• identifying mineral phases and measuring volume fractions of the mineral phases relative to total volume of a rock sample by performing X-ray diffraction (XRD) analysis of fine powder of the rock sample;
• inputting measured data of bulk density, total porosity, and volume fractions of the mineral phases into a computational model executing on a computing system;
• processing the data inputted into the computational model by displaying a main user interface which includes an input pane, a mineral composition pie chart, and a predicted properties pane;
• determining static and dynamic mechanical properties of the rock sample based on the processed data;
• identifying an oil and gas reservoir based on the dynamic mechanical properties of the rock sample;
• estimating a reserve of the oil and gas reservoir based on the dynamic mechanical properties of the rock sample;
• designing effective production strategies for the oil and gas reservoir based on the static mechanical properties of the rock sample;
• and
• selecting appropriate drilling tools and hydraulic fracturing operations for the oil and gas reservoir based on the static mechanical properties of the rock sample.
