...-permeability siltstone/sandstone intervals across the Permian Basin (low resistivity pay). In such cases, the Archie equation estimate of water saturation could be overly pessimistic, leading to less-than-optimal field development. Traditionally, nuclear magnetic resonance (NMR) is used to cross-check...

... Abstract A prediction method for the EUR (Estimated Ultimate Recovery) of tight sandstone gas reservoirs based on a composite machine learning approach was proposed and applied in the M tight sandstone reservoir in Canada. This method extrapolated geological parameters such as porosity...

... sandstone samples using CO 2 and water. The tests were done on cylindrical samples with dimensions of 4″ in diameter and 5.5″ in length. Samples with different petrophysical and elastic properties were used. We recorded the injection pressure and monitored acoustic emissions (AEs) concurrently using...

... Abstract This study observed hydraulic fracture propagation, arrest, and closure in permeable rocks. The experiment was conducted on a Molasse sandstone block in a true triaxial state of stress. The study monitored fracture opening at the wellbore and fluid pressure measurements to understand...

... Abstract The distribution of oil and water in tight sandstone reservoirs is complicated, with pore throat size and wettability being the main influencing factors. This study proposes an experimental method for determining core oil-water pore throat distribution based on nuclear magnetic...

In the study area, the dominant curvature anomalies are associated with specific underlying structures related to differential compaction and drape observed in a Cretaceous Upper Mannville channel sandstone reservoir. Sediment drape due to differential compaction over this channel sandstone is visible...

... of sandstone is present. The primary siliciclastic sediment source was from the Northern Shelf, and these sediments accumulated mainly in axial positions of the MB. Organic-rich and carbonate-bearing mudrocks (i.e., mixed siliciclastic-carbonate shales) accumulated predominantly on the structurally-low...

... Abstract The Lewis Shale is a turbidite system encompassing sandstones, siltstones, and organic-rich shales, deposited during the last Cretaceous seaway transgression. It is informally subdivided into three members; a lower member (characterized by high clay and organic matter content...

... Abstract The Upper Triassic Xujiahe formation is very tight formation located in highly tectonically stressed zones in the Western Sichuan Basin of China. The second and fourth members (abbreviated as T3X2 and T3X4, respectively) of the Xujiahe formation are gas-bearing tight sandstones...
