Abstract: A method of constructing a mechanical earth model (MEM) includes integrating a density logging data set to compute vertical stress and applying correlation models or equations to estimate a pore pressure and mechanical properties. The method also includes calibrating the pore pressure with drill stem test data, calibrating the mechanical properties with laboratory tests on core plugs or on rock cuttings, estimating a minimum horizontal stress using correlation models, and calibrating the minimum horizontal stress with minifrac tests. The method further includes estimating a maximum horizontal stress using the correlation models while assuming one or more correlation parameters, calibrating the maximum horizontal stress with a global pattern of tectonic strains and a basin stress regime, evaluating one or more breakout regions using the MEM, a trajectory of a well, and a geometry of a pilot hole, and comparing the one or more breakout regions and a caliper logging data set.

Abstract: A method for developing a procedure for pretreating a section of a wellbore prior to hydraulic fracturing stimulation of the section of the wellbore includes determining an optimized notch geometry and determining an optimized chemical treatment for the section of the wellbore. The optimized notch geometry is determined by modeling a notch in the section of the wellbore using a computing system, simulating a pressure increase in the section of the wellbore and on the notch from a hydraulic fracturing stimulation, identifying breakdown pressure in the section of the wellbore, and repeating the modeling, simulating, and identifying to determine the optimized notch geometry in the wellbore as the notch having a lowest breakdown pressure. The optimized chemical treatment is determined by determining a rock type in the section of the wellbore and determining a conditioning fluid that reduces the tensile strength of the rock type.

Abstract: A method may include obtaining well log data for various wells regarding a geological region of interest. The well log data may correspond to various well logs with different logging types. The method may include assigning, using a grouping algorithm, subsets of the well log data to various groups based on one or more geological attributes. The method may include determining, using the groups and a machine-learning algorithm, various well zones for different portions of a respective well among the wells. The method may include determining interpolated log data using the well log data, the well zones, and an intrawell interpolation process. The method may include generating a formation property volume based on the interpolated log data and the well log data.
