TL;DR: The mechanism of natural hydraulic fracturing is incompatible with the characteristics of most regional fracture sets as discussed by the authors, and the differential stress required for initiation and propagation of regional fractures is well below that necessary for shear failure.

TL;DR: In this paper, two fracture sets dominate the Lisburne Group carbonates of the North Slope subsurface and the nearby northeastern Brooks Range fold and thrust belt, and they are overprinted by younger east-northeast-striking fractures related to subsequent contractional deformation.

TL;DR: In this article, a hydraulic fracture stimulation conducted during 1983--1984 in non-marine, deltaic, Mesaverde strata at a depth of 7100 ft (2164 m) was cored in a deviated well in 1990.

TL;DR: Paleohydrologic reconstructions have been applied to downhole measurements made in the U.S. Department of Energy's Multi-Well Experiment (MWX) wells in order to derive sand-body widths for the nonmarine part of the Mesaverde Group (Cretaceous) in the east-central part of Piceance Creek basin of northwestern Colorado as mentioned in this paper.

TL;DR: In this article, horizontal cores from sandstone-siltstone reservoirs in the Spraberry Formation (Midland basin, west Texas) have documented two systems of dramatically different yet dynamically compatible natural fractures, in reservoirs separated vertically by only 145 ft (44 m).
