(Texas A&M University, 2008-10-10)The Winland R35 method [Log R35 = 0.732 + 0.588 (Log Kair) 0.864 (Log O)] is based on the relationship between porosity, permeability, and pore throat radius at the point of 35% mercury saturation in capillary pressure ...
-
(2016-02-12)Carbonate reservoirs are a major source of oil and gas produced across the world. Carbonate reservoirs are distinct from sandstone reservoirs in terms of deposition and characteristics. Sandstones are formed by deposition ...
-
(2012-10-19)Spent acid retention in the near-wellbore region causes reduction of relative permeability to gas and eventually curtailed gas production. In low-permeability gas carbonate reservoirs, capillary forces are the key parameters ...
-
(2009-05-15)Carbonate reservoirs are characteristically heterogeneous in reservoir quality and performance owing to the variety of processes that influence pore formation. Additionally, porosity and permeability do not conform to ...
-
(2020-12-01)The ocean is absorbing an increasing amount of carbon dioxide (CO2), which is rapidly changing seawater chemistry. As seawater CO2 increases, ecosystem calcification is hindered by the resulting decline in pH, aragonite ...
-
(2023-01-04)Coal balls are carbonate and pyrite concretions that contain permineralized peat, or fossilized plants, preserved at the cellular level, which have been used to reconstruct Pennsylvanian and Early Permian swamp communities ...
-
(2018-02-05)Allochthonous carbonate deposits in the First Bone Spring Carbonate (FBSC) interval exhibit complex architectural and compositional heterogeneity. The episodic and chaotic depositional nature of these deposits results in ...
-
(2021-07-15)The year 2020 Common Era (CE) observed the highest number of named tropical cyclone events since the instrumental record began in 1850 CE. Most downscaled models suggest that the frequency and destructive potential of major ...
-
(2015-12-12)The assessment of directional permeability in carbonate formations is challenging due to their complex pore structure and anisotropic pore-network properties. Previous studies have shown that permeability is controlled by ...
-
(2017-07-28)The oil industry has been utilizing different acid systems, both organic and inorganic, to stimulate sandstone and carbonate reservoirs. Among these, hydrochloric acid (HCl) is the most commonly used acid because it is ...
-
(2015-12-12)The paper presents a petrophysical modeling and permeability analysis approach for a tight carbonate formation. The formation samples used in this study are from the Tarim oil field Yingshan formation, deposited during ...
-
(2009-05-15)Fluid flow mechanisms in a large naturally fractured heterogeneous carbonate reservoir were investigated in this manuscript. A very thin layer with high permeability that produces the majority of production from specific ...
