Simulating Core Floods in Heterogeneous Sandstone and Carbonate Rocks
For the sandstones we use the experimental coreflood data of Reynolds and Krevor ; Reynolds et al. and for the carbonate rocks, the data set of Manoorkar et al. . The sandstones exhibit distinctly orientated planar bedding, whereas the carbonates are characterized by isotropic cementation of varying length scale.

Measurements of CO2 Trapping in Carbonate and Sandstone Rocks
/carbonate will be equilibrated together before running the capillary trapping experiment. The apparatus used for sandstone rocks was modified so that the geochemical reaction between CO 2 /rock was accounted for. Samples are taken and analysed to ensure that the brine/CO 2 mixture is saturated with carbonate minerals. In Indiana, the CO 2

Digital Models of Heterogeneous Sandstone and Carbonate Rock Cores
This dataset contains digital models of three carbonate (Indiana limestone, Estaillades limestone and Edwards Brown Dolomite) and two sandstone (Bentheimer and Bunter) cores with varying degrees of heterogeneity types and length scales. The models define the spatial distribution of porosity and capillary heterogeneity, and can simulate core floods.

EVALUATION OF MULTI-STAGE SANDSTONE ACIDIZING USING AN ORGANIC MUD ACID
In this study, coreflood experiments were conducted on Bandera sandstone cores (1.5 in. × 6 in.) at a flow rate of 4 cm3/ min and temperature of 140°F. A mixture of formic acid and HF was used as an organic mud acid. Preflush of hydrochloric and formic acid was employed to remove carbonate minerals. Bandera sandstone cores contain a

Effect of the surface charge of silica nanoparticles on oil recovery
After this period of time, sandstone cores were removed from the crude oil and placed in an oven until dried. The aged sandstone core pieces were immersed into an aqueous solution of 0.3% NaCl containing different concentrations of silica materials (100 or 200 mg/L) for 24 h. Afterward, the samples were removed and placed in an oven until dried.

Brine-Dependent Recovery Processes in Carbonate and Sandstone Petroleum
the potential of recovering additional oil in sandstone and carbonate reservoirs. Sandstone and carbonate rocks are composed of completely different minerals, with varying degree of complexity and heterogeneity, but wettability alteration has been widely considered as the consequence rather than the cause of brine-dependent recovery.

Sandstones with Carbonate Cement, Coal Exploration Core, Kentucky
Carbonate-cemented sandstones may have any of the sedimentary structures seen in other kinds of sandstone. Two kinds of carbonate cement are common in Carboniferous coal fields: (64X CaCO 3) Calcite-cemented sandstone (64X FeCO 3) Siderite-cemented sandstone; Both varieties are generally harder than typical gray sandstones, which they resemble.

How sandstone porosity and permeability vary with diagenetic minerals
Known sandstone reservoirs are in Upper Jurassic–Lower Cretaceous deltaic sandstones on the Scotian Shelf and deep-water turbidites in salt-bound minibasins on the Scotian Slope, which host natural gas and minor oil. Detrital supply differs between the eastern, central and western parts of the basin (Tsikouras et al., 2011, Zhang et al., 2014).
