Fracture Growth Kinematics in Tight Sandstone Reservoirs
… connectivity of fractures in low permeability sandstone reservoirs is essential for optimal hydrocarbon exploitation. In a linear elastic fracture mechanics framework, it is generally assumed that fractures widen in aperture while they propagate in length or height. However, it is also …

Novel insights into low salinity water flooding enhanced oil recovery in sandstone reservoirs
… for increased oil recovery during LSWF in both sandstone and carbonate reservoirs is wettability alteration of the rock surface from oil-wet to water-wet. LS water imbibed into the low water-wet zones, the water wetness of the rock increased after injecting LS water, and in turn, microscopic …

Controls on deposition, lithologic variability, and reservoir heterogeneity of prolific western interior shelf sandstone reservoirs: Tocito and El Vado sandstones, San Juan Basin, NM
The Tocito and El Vado Sandstones have proven to be highly prolific hydrocarbon reservoirs in the largest domestic onshore conventional gas basin in the U.S., the San Juan Basin (SJB). Application of modern drilling technology and favorable petroleum commodity prices have resulted in increased …

High-Resolution Inversion and Spectral Decomposition: Case Studies from the Bohaiwan Basin, China
… to detect or map the lateral continuity of these reservoirs. Volcanic activity in the Liaohe area resulted in basalt layers with strong reflectivity adjacent to sandstone reservoirs. This makes it difficult to image the reservoir as side lobes of the strong base basalt reflector obscure the …

Surfactant-free Aluminum Silicate-based Nanofluids for Enhanced Oil Recovery from Austin Chalk Carbonate Reservoirs
… for enhancing oil recovery in carbonate reservoirs has received great attention from various researchers across the oil and gas industry. In contrast to sandstone reservoirs, carbonates are naturally neutral-wet or preferentially oil-wet. Understanding the mechanisms associated with …

Comprehensive evaluation of a novel EOR method-coupling low salinity water flooding and preformed particle gel to enhance oil recovery in fractured reservoirs
… economic and environmental problem as more reservoirs are maturing. Water channeling, one of the primary reservoir conformance problems, is caused by reservoir heterogeneities that lead to the development of high-permeability streaks. The recovery of oil from carbonate reservoirs is usually …

How does cement influence the mechanical properties of sands and sandstones?
… bands can act as barriers and baffles in sandstone reservoirs. An increasing number of deformation bands have been studied in poorly cemented sandstones, yet there are questions about how grains can break (rather than slide past one another) in such loose sediments/rocks. The strength and …

Computational fluid dynamics modelling of multi-phase flow transition in presence of solid particles.
… flow common in the oil and gas industry, as oil reservoirs contain mixtures of oil, gas and water with sand particles from sandstone reservoirs. Accurate design of oil and gas production equipment greatly depends on detailed understanding of this flow phenomena. Previously, multi-phase studies …

Application of surfactant-polymer enhanced oil recovery in a high- salinity, high-temperature carbonate reservoir
… increases, and the discovery of new conventional reservoirs diminishes, the need of using enhanced oil recovery (EOR) methods, such as chemical flooding, grows. A widely used type of chemical EOR is surfactant-polymer flooding (SP). In SP flooding, a surfactant reduces the interfacial tension …

Geomechanical impact of bio-competitive exclusion chemical on reservoir rocks.
… and potential geomechanical effects of treating sandstone and carbonate reservoir rocks with a biocompetitive exclusion (BCX) chemical (sodium nitrate) under static and flooding conditions. The flooding approach was adopted to study the effects of varying chemical concentrations on sandstone …

Geological and Geochemical Investigation of the Petroleum Systems of the Permian Basin of West Texas and Southeast New Mexico
… the Delaware and Midland basins to Pennsylvanian sandstone reservoirs in the Eastern Shelf and Permian carbonate reservoirs in the Central Basin Platform and the Northwest Shelf. The Woodford shale began expelling petroleum during Early to Late Permian. Migration occurred along vertical pathways …

Uncertainty reduction in reservoir parameters prediction from multiscale data using machine learning in deep offshore reservoirs.
… reserve estimates and pressure transients. Sandstone assets from the North Sea were used to establish the technique for uncertainty reduction, using machine learning as well as empirical models after data digitization and cleaning. These models were built (trained) with observed data using …

Caprock integrity evaluation for geosequestration of CO2 in depleted petroleum reservoirs.
… the CO2 can be stored in depleted petroleum reservoirs or aquifers - or, it might be necessary to inject CO2 with a small amount of these gas impurities to save cost. Moreover, during CO2 geosequestration in reservoirs, pressure variations during injection and storage could force some amount …

Reservoir quality and well performance analysis in the middle member of the Lewis shale, greater Green River basin, Wyoming
impacting their habitat and reproduction areas. The Wyoming Game and Fish Commission published some recommendations to lessen the impact of oil and gas development on the wildlife to mitigate these effects (WG&F, 2007). These efforts include buffers around nests, migration corridors, concentration …

Investigating the effect of perforation diameter and carbon dioxide bubble size distribution on heavy oil recovery
… analyses show that heavy oil recovery process in sandstone reservoirs can be significantly improved by the application of well completion with smaller perforation diameter.

Experimental and Modelign of Foam Physics in Porous Media
… implemented in many Western Canadian heavy oil reservoirs in the last two decades as the field-scale primary production process. However, A typical CHOPS primary production process has a heavy oil recovery factor of 5–15% of the original oil-in place (OOIP) (Gökhan et al., 2015). Therefore, an …
