Cleat and Fracture Systems in Coal with Implications for Strength, Hydrofracking, and Gas-Water Flow Mechanisms: A Critical Review.

The cleat is a characteristic structural feature found within coal lithotypes, often in a regular pattern. The presence of cleats and fractures in coal is advantageous for miners, as they provide weak planes that aid in extraction. However, the stability of pillars and roofs relies on factors such as cleat/fracture orientation, spacing, and intensity.

Influence of Petrographic, Geochemical, and Pore-Associated Matrix Characteristics on CH and CO Sorption of Coal and Shale from Early Permian-Gondwana Deposits, India.

CO storage in various geological formations presents a feasible option for reducing greenhouse gas emissions (GHG) in the atmosphere. The most viable and technoeconomic method involves injecting CO into deep, unmineable coal seams and shale beds to enhance CH recovery. CO exhibits a greater affinity with coal, shale, and associated siliciclastic-organic rich rock compared to CH.

Various Extraction Techniques of Curcumin-A Comprehensive Review.

Curcumin, the active component of the rhizome of , is a safe substance whose applications are extensively used in medicinal, biological, pharmacological activities, and food cosmetic additives. In the field of medicine, curcuminoids have a greater impact; they have been associated with the suppression of neuropathic pain, depression, angiogenesis, tumorigenesis, diabetes, and diseases of the liver, skin, and pulmonary systems, as well as cardiovascular and nervous systems. These are in high demand and have high market potential and inflated costs.

Petrographic and Geochemical Controls on Methane Genesis, Pore Fractal Attributes, and Sorption of Lower Gondwana Coal of Jharia Basin, India.

The Barakar coal seams of Jharia Basin have been evaluated for the geochemical and petrographic control of coalbed methane (CBM) reservoir characteristics. The coal core samples are analyzed for the total gas content, gas chromatography, stable isotopes (δC), and geochemical, petrographic and vitrinite reflectance. The significant face (1.

Variation in Pore Structure and Associated Fractal Dimensions of Barakar and Barren Measures Carbon-Rich Gas Shales of Jharia Basin, India.

The carbon-rich Barakar and Barren Measures shale beds of the Jharia basin were evaluated for variation in pore size, pore structure, and fractal dimensions. The shale core samples were obtained from exploratory boreholes drilled at the Jharia basin. The shale samples were analyzed for organo-inorganic composition by FTIR, pore size, and pore structure using BET low-pressure N adsorption and pore geometry through FE-SEM photographs.
