The purpose of the work is to refine the initial construction of the minimum horizontal stress curve, considering the current pore pressure. Pore pressure is found in basic calculation equations, but published sources lack of a method for converting scalar values of pore pressure into a curve to build a geomechanical model as part of the input data of the hydraulic fracturing simulator.
The scientific novelty of the work lies in the construction of a pore pressure curve based on scalar quantities for use as input data for the hydraulic fracturing simulator. For the first time, a combined method was applied, including refinement of the components of the minimum horizontal stress equation using both the Bio constant and the tectonic influence coefficient, and the conversion of pore pressure data into a curve. As a result, we obtained a calculation method that allows us to obtain refined fracture simulator input data based on a standard data set.
