Effect of silica nanoparticles with different charge profiles on the wettability of Berea sandstone cores and oil displacement. Wettability alteration of rock reservoirs plays an important role in oil recovery and it is used to determine the efficacy of nanomaterials during the oil recovery process [].To investigate the effect of the surface Hydraulic fracturing is an important technology for the development of unconventional gas such as tight sand gas. In this paper, a series of fracturing experiments were conducted on hollow cylindrical sandstone specimens with a diameter of 50 mm to investigate the initiation, propagation, and closure of hydraulic fractures. In addition, Initiation, propagation, closure and morphology of hydraulic

Bentheimer sandstone revisited for experimental purposes

Introduction. Bentheimer sandstone (BS) is a shallow marine formation deposited during the Lower Cretaceous. It forms a reservoir for oil and on the border between the Netherlands and Germany, outcropping in Bentheim with shallow oil reservoirs in between Enschede and Schoonenbeek (Dubelaar and Nijland, 2015, Fuchtbauer, Chemical analysis of cuttings and core samples is less frequently applied to sandstone and carbonate successions but can be achieved using benchtop X-ray fluorescence (Gier et al. 2015), portable X-ray fluorescence and inductively coupled plasma-based tools used to solve questions of lithology determination, sediment provenance and chemical Petroleum reservoir quality prediction: overview and contrasting

Acidizing of conventional and tight sandstone formation using

Stimulation of the sandstone reservoir requires a mixture of acids such as mud acid, which assist in enlarging the microscopic paths by dissolving the siliceous fines or clays near the well-bore region. As a result, the formation permeability and porosity can be enhanced. In deeper wells, the temperature exceeds 200 °F, at these temperature A several-fold increase in the flow rate of liquids in synthetic and natural sandstone cores was observed upon application of direct electrical current. These results present the possibility of using direct electric treatment to stimulate wells or enhance water injectivity.Introduction. Electroosmosis has long been applied in soil engineering, and Effect of Direct Electrical Current on Permeability of Sandstone Cores

Characteristics and Impact of Asphaltene Precipitation During CO2

Abstract. Characteristics and impact of asphaltene precipitation during CO2 injection are investigated for a Middle East crude oil in both sandstone and carbonate cores through phase behavior studies, corefloods and analyses of the deposition process using a compositional simulator. In phase behavior studies, a light-scattering technique Cissokho et al. reported a 10% increase in recovery by injecting low-salinity brine into sandstone cores that contained illite and chlorite and were free from kaolinite.
