Abstract Modified or low-salinity waterflooding of carbonate oil reservoirs is considerable economic interest because potentially inexpensive incremental production. The injected modified brine changes the surface chemistry rock and crude interfaces detaches some adhered oil. Composition design to enhance recovery determined by labor-intensive trial-and-error laboratory corefloods. Unfortunatel...

In this study, fracture orientations in carbonate reservoirs were determined using a multicomponent velocity analysis based on shear wave splitting. The is the estimated velocities of large seismic events with different polarizations. fractured zone dominant orientation, weak amplitude split events, including noise, result waves that are polarized toward symmetry and anisotropy axes propagate c...

Carbonate rocks of the Triassic deposits South Mangyshlak basin are investigated in this paper for their boundary values, which important interpretation field geophysical data as well perforation and blasting. Based on lithological composition, classified either terrigenous or carbonate reservoirs. reservoirs found Middle strata containing volcanogenic dolomite limestone rocks. A complex type r...

Rhodoliths are benthic calcium carbonate nodules accreted by crustose coralline red algae which recently have been identified as useful indicators of biomineral changes resulting from global climate change and ocean acidification. This study highlights the discovery that the interior of rhodoliths are marine biodiversity hotspots that function as seedbanks and temporary reservoirs of previously...

Carbonate reservoirs are one of the most important fossil fuel sources, and acidizing stimulation is a practical technique for improving recovery carbonate reservoirs. In this study, improved two-scale continuum model, including representative elementary volume (REV) scale model upscaling used to study process with an isolated fracture. Based on comprehensive discussion presented effect physica...
