Abstract: An apparatus and methods for forming a transverse fracture in a subterranean formation surrounding a wellbore including measuring a property along the length of the formation surrounding the wellbore, forming a stress profile of the formation, identifying a region of the formation to remove using the stress profile, removing the region with a device in the wellbore, and introducing a fluid into the wellbore, wherein a transverse fracture is more likely to form than if the region was not removed. Some embodiments benefit from computing the energy required to initiate and propagate a fracture from the region, optimizing the fluid introduction to minimize the energy required, and optimizing the geometry of the region.

Abstract: Systems and methods presented herein are configured to optimize a hydraulic fracturing job design through the use of an advanced wellbore proppant transport model and coupled hydraulic fracture simulator. For example, a data processing system is configured to simulate, via a wellbore flow simulator being executed by the data processing system, a distribution of proppant between a plurality of perforation clusters of a wellbore during a hydraulic fracturing job design; to simulate, via a hydraulic fracture simulator being executed by the data processing system, one or more hydraulic fractures propagating through a subterranean formation through which the wellbore extends; and to automatically adjust, via fracturing design software executed by the data processing system, the hydraulic fracturing job design by dynamically exchanging data relating to the distribution of the proppant and the one or more hydraulic fractures between the wellbore flow simulator and the hydraulic fracture simulator.

Abstract: A method can include receiving strain data associated with propagation of a hydraulic fracture in a subsurface geologic region; performing a comparison between the strain data and simulation results generated using a mesh model of the subsurface geologic region and enrichment equations that represent one or more discontinuities in the subsurface geologic region; and, based on the comparison, characterizing the subsurface geologic region.

Abstract: Anisotropic elastic properties and subsequently in situ stress properties for a rock formation surrounding a wellbore are computed from rock physics and geomechanical models. Mineralogy data measured from DRIFTS on cuttings from the wellbore and rock physics and geomechanical models that have been log-calibrated in another wellbore are used in the computation. The method includes: (1) Defining and calibrating rock physics and geomechanical models using data from the first wellbore; (2) using DRIFTS analysis to measure mineralogy data on rock cuttings obtained through drilling operation in the second wellbore; and (3) using previously calibrated models to estimate in situ stress properties, including a stress index and the minimum principal stress magnitude.
