Abstract: A method for planning and drilling a well includes receiving geomechanical and geological data for a subterranean domain, and receiving an initial well trajectory including a well path and survey points. The method includes conducting a wellbore stability analysis along the well trajectory based in part on the geomechanical and geological data. Conducting the wellbore stability analysis includes identifying a subset of the well path intervals along the well trajectory as having a risk for instability. The method includes calculating a geomechanics nudge for one or more survey points along the well trajectory. The geomechanics nudge is calculated as a derivative of the wellbore stability at the one or more survey points. The method includes modifying the one or more survey points and the one or more well path intervals connected thereto based in part on the geomechanics nudge to generate a modified well trajectory.

Abstract: Methods, computing systems, and computer-readable media for predicting pore pressure. As an example, the method includes receiving data representing a subterranean domain, modeling the domain based on the data, ranking the data, testing and validating the model, calibrating the model, and predicting a pore pressure in the domain.

Abstract: A method can include receiving data that characterizes anisotropy of a formation; receiving a model that models one or more planes of weakness in an anisotropic formation; and, based at least in part on the model and the data, outputting information germane to stability of a bore in an anisotropic formation.

Abstract: A method may include acquiring NMR data and sonic data for a borehole in a subsurface geologic region; inverting the NMR data and the sonic data to determine volume fractions for a number of classes of pore types, where the classes include shape and size-based classes; and characterizing the subsurface geologic region based on the volume fractions for the number of classes.
