Determining one or more parameters of a well completion design based on drilling data corresponding to variables of mechanical specific energy

A non-transitory storage medium comprising program instructions which when executed by a processor perform the operations of:

• receiving data regarding a drilling operation of a well;
• calculating values of mechanical specific energy (MSE) from the received data;
• categorizing the MSE values into a plurality of groups according to different ranges of MSE values;
• mapping groups to which the MSE values are categorized to locations along the drilled well;
• creating a geomechanical model of the mapped groups;
• demarcating subsets of the geomechanical model such that lengths of the subsets correspond to sections of the drilled well;
• determining one or more parameters of a well completion design for the drilled well using the demarcated subsets of the geomechanical model, wherein the one or more parameters are selected from a group consisting of locations of perforation clusters, quantities of perforation clusters, locations of fracking stages, lengths of fracking stages, and one or more parameters to induce and maintain hydraulic fractures fractures including selecting fracturing fluid type and proppant type;
• and
• creating the well completion design with the one or more parameters.
