Evaluating the role of dissolved silica for dolomite formation in evaporitic environments: Insights from prolonged laboratory experiments
( Elsevier , 2024 , Article)The mineral Dolomite CaMg(CO3)2 is a common constituent of sedimentary rocks. Despite centuries of research, the mechanism of its formation remains elusive and debated. Recent studies have shown the presence of silica in ... -
Integrated approach for closure correction of mercury injection capillary pressure measurements
( Elsevier , 2023 , Article)Closure correction is a key requirement for a reliable petrophysical evaluation using mercury injection capillary pressure (MICP). The available correction methods rely on identifying deflection points on capillary pressure ... -
CFD estimation of gas production in tight carbonates using single and dual-porosity models
( Nature Research , 2023 , Article)Tight Carbonate reservoirs are regarded as one of the most complex reservoir formations due to the heterogeneity and complexity of their mineral composition, pore structure, and storage model. It is uncommon to study the ... -
Novel methodology to couple decline curve analysis with CFD reservoir simulations for complex shale gas reservoirs
( John Wiley and Sons Inc , 2024 , Article)Shale reservoirs are highly complex and are difficult to study using conventional reservoir simulation tools. This study introduces a novel methodology for estimating production from complex shale gas reservoirs by coupling ... -
Altering shale permeability by cold shock
( Elsevier , 2024 , Article)The matrix permeability of shale is on the order of nanodarcy (nD), and hydrocarbon recovery from it is economical only after hydraulic fracturing. Another fracturing technique, which is often overlooked, is cryogenic ... -
Raman Spectroscopic and Microbial Study of Biofilms Hosted Gypsum Deposits in the Hypersaline Wetlands: Astrobiological Perspective
( Mary Ann Liebert Inc. , 2023 , Article)Gypsum (CaSO4.2H2O) has been identified at the surface of Mars, by both orbiters and rovers. Because gypsum mostly forms in the presence of liquid water as an essential element for sustaining microbial life and has a low ... -
