Methodology of organic-rich shale lithofacies identification and prediction: A case study from Marcellus Shale in the Appalachian basin
The success of shale gas in North America has attracted increased interest in “unconventional” reservoirs. Two critical factors for shale-gas reservoirs are units amenable to hydrologic fracture stimulation and sufficient natural gas content. The effectiveness of hydrologic fracture stimulation is influenced by rock geomechanical properties, which are related to rock mineralogy. The natural gas...
متن کاملIdentifying organic-rich Marcellus Shale lithofacies by support vector machine classifier in the Appalachian basin
Unconventional shale reservoirs as the result of extremely low matrix permeability, higher potential gas productivity requires not only sufficient gas-in-place, but also a high concentration of brittle minerals (silica and/or carbonate) that is amenable to hydraulic fracturing. Shale lithofacies is primarily defined by mineral composition and organic matter richness, and its representation as a...
متن کاملSecondary Minerals and Constituents of the Marcellus Shale Formation
This work identifies unknown crystals found encrusting the Marcellus Shale Formation at the Mapleton Quarry locality in Central Pennsylvania, over the course of a month. The outcrop has been exposed for sufficient time for there to be advanced chemical weathering, allowing for the presence of secondary minerals to form and changes in the composition of the surrounding water table and environmen...
متن کاملMineral surface control of organic carbon in black shale.
We show that 85% of variation in total organic carbon can be explained by mineral surface area in a black shale deposit from two locations in the late Cretaceous Western Interior Seaway, United States. This relation suggests that, as in modern marine sediments, adsorption of carbon compounds onto clay mineral surfaces played a fundamental role in the burial and preservation of organic carbon. O...
متن کاملAtmospheric emission characterization of Marcellus shale natural gas development sites.
Limited direct measurements of criteria pollutants emissions and precursors, as well as natural gas constituents, from Marcellus shale gas development activities contribute to uncertainty about their atmospheric impact. Real-time measurements were made with the Aerodyne Research Inc. Mobile Laboratory to characterize emission rates of atmospheric pollutants. Sites investigated include productio...
