... is consistent with outcrop measured UCS located in the same region. The importance of layered, variable-strength rocks to natural fracture development is observed in an outcrop exposure of the Austin Chalk in central Texas. Chalk-rich facies (high UCS) were more fractured and had a broader deformation area...

... Abstract The objective of this work is to present a new approach for the study and characterization of the Vaca Muerta Formation through the innovative technology of virtual outcrops. The project is part of a new co-opetition effort between YPF and Shell companies, to contribute and enrich...

... in the Duvernay mostly vary according to changes in carbonate content, whereas in the Woodford changes are according to quartz content. However, in both cases a systematic alternation of two distinct rock types is evident at the cm-scale in outcrops and cores: organic-rich and calcite-rich facies for the Duvernay...

... the sweet spots in the area. A detailed description of two continuous analogous outcrop coring, constrained the variation of organic content along the Eagle Ford Formation. The two cores comprise a complete record of the Eagle Ford Formation with thickness of 47.5 m and 86.8 m, respectively. Lower Eagle...

... Abstract Outcrop and subsurface cores are sampled for a variety of low-cost rock analyses, including: Chemical (XRF) and mineralogical (XRF, XRD, petrography) composition and stratification, hardness (Leeb rebound hardness tester); microfabric, porosity and permeability (SEM); organic content...

.... But is it beneficial to stimulate these features and what are the potential consequences? An analysis of structural features from the Marcellus and Duvernay formations has been undertaken, with static characterization (seismic, image logs and outcrops), dynamic characterization (fracture diagnostics and well...

Besides, fracture lengths were studied at the outcrops. Matrix porosity and permeability were obtained from the logs...

The subsurface "lower" Eagle Ford formation, which corresponds to the middle member in outcrops around the Del Rio, Texas area (Lock and Peschier, 2006), is a focus of exploration and production efforts.
