Shale mineralogy
Apr 1, 2014 · Where smectite is a major or significant clay component of a shale, as in Classes 1 and 2, then the shale instability can be readily rationalized in terms of the well known swelling behaviour of the smectite minerals in water and when saturated with different cations (Mooney et al., 1952; Norrish, 1954). Since shale is largely defined by its grain size, it can be composed of a pretty wide variety of minerals and rock fragments. Shale is not defined by its mineralogy, but because of the way it forms it is almost always made from only a handful of possible components.

The characterizations of microfractures within shale, and their associations with bedding, mineralogy and loading, are important for shale gas exploration and related engineering safety.Shale oil is a vital alternative energy source for oil and gas and has recently received an extensive attention. Characterization of the shale oil content provides an important guiding significance for resource potential evaluation, sweet spot prediction, and development of shale oil. In this paper, the mechanism, evaluation and influencing factors of oil retention in shales are reviewed. Oil ...Shale formations play key functions in geologic carbon sequestration (GCS), and it is important to understand the interactions of water-bearing scCO 2 fluids with the minerals …Shale is a lithified mud — a sedimentary rock composed mostly of clay- and silt-sized grains. There are several ways to define shale. Some definitions are rather narrow. Glossary of Geology published by the American Geological Institute defines shale as a laminated, indurated rock with >67% clay-sized minerals 1.
Summary: The Upper Jurassic (Kimmeridgian to Lower Tithonian) Haynesville and Bossier Shales of East Texas and northwest Louisiana are currently one of the most important shale-gas plays in North America, having high IPs, steep decline rates, EURs estimated at 3 to 7 Bcf per well of each formation, and play resources estimated together in the hundreds of trillions of cubic feet (Fig. 1).This study aims to investigate mineralogy, depositional environment and rock mechanical properties of Cambay Shale Formation in Jambusar-Broach block of South Cambay Basin, India, by an integrated approach of combining wireline logs and laboratory studies.

Diagenetic shale minerals are carriers for inorganic pores. Since the mineral compositions of shales in the Wufeng-Longmaxi Formation in the study area are complicated, the types and characteristics of pores developed in different minerals are also varied. Inorganic pores involve intercrystalline pores, transgranular pores, and dissolution holes.study of mineralogy.

Jun 3, 2015 · Rock formations of pure clay minerals are rare. More typically, several species of clay mineral are associated together with clay-sized and silt-sized quartz, mica, and other rock grains. This association is known widely as "shale." In sandstone reservoirs, clay-mineral content typically ranges from 0 to approximately 10% BV. @article{AndreObayanju2023EvaluatingTP, title={Evaluating the Potentials of Drilling Mud Production from Clayey Solis Derived from Imo Shale Formation in Okada, Near Benin, South Western Nigeria}, author={Oluwatomilola Andre-Obayanju and Osita Christopher Okeke and Sikiru Adeoye Salami}, journal={European Journal of Theoretical …
Notice how the Kinderhook Shale and the Woodford Shale show very similar CGR values. Because the CGR is the sum of the contributions from potassium and thorium sources, this demonstrates that their clay mineralogy is fairly similar.Exxon Mobil Corp.’s head of shale remained in a Texas jail Sunday after he was arrested for sexual assault at a hotel near Houston last week, police said.
