Bedding-parallel veins of calcite ‘beef’ and blocky calcite are confined to the overpressured interval in the Wolfcamp. They correspond...

... Abstract A series of triaxial compression tests were performed on 4 Eagle Ford shale and 4 Woodford shale horizontal plugs. Shear reactivation of preexisting veins occurred in 3 of the Woodford shale samples. The behavior of these veins was compared to the Byerlee's friction law at low normal...

... of petroleum expulsion is complimented with the force of crystallization to explain a possible mechanism for generating "beef fractures." Bedding-parallel fracturing is always favored during petroleum expulsion in organic-rich shales. The mechanism of forming veins, in general, has long been debated. It has...

... and pyrophyllite, a strongly anisotropic (19%) metamorphic rock similar chemically and mechanically to shale with extremely low porosity and permeability. As the second group, shale samples (18% anisotropy) from Wolfcamp formation are studied. The calcite filled veins are observed to be mostly subparallel...
