... investigated the extent and timing of misaligned well orientations on production. Over 71,000 wells from eight US unconventional plays, such as Bakken, Barnett, Eagle Ford, Haynesville, Marcellus, Granite Wash, and Utica, were analyzed for the misalignments of well horizontals with minimum horizontal stresses...

.... In contrast, the Delaware Basin has a greater variety of well orientations and a different relationship with Shmin. Delaware Basin wells show highest average production (∼35 BOE/ft) from wells drilled 5° to 25° clockwise from Shmin. In contrast to theoretically-predicted behavior, Permian Basin horizontal...

..., and it was characterized by the length, width, height and orientation obtained from microseismic data. Geological and engineering features influencing the SRR were identified and extracted. Prediction models for the four characterization parameters were established separately based on stacking ensemble learning algorithm...

... in the various sections of the Buckinghorse Formation. The results were comparable at the 0° and 90° orientation while the 45° orientation showed anomalous failure patterns prompted by the slippage/shearing along bedding planes, and demonstrated that there is a dominant change in the failure mechanisms when...

... Abstract Unconventional rock commonly includes sets of natural fractures of different orientation, intensity, and spatial variability. Observation of in situ natural fractures depends on the collection of images logs and core, providing a peek into the subsurface. Predicting natural fractures...
