Several laboratory studies observed wettability alteration of carbonate rocks towards a more
water-wet state through modifying the composition of injected water. The change in …

The rapid increase in the global economy and expansion of industry has contributed to the
rapid depletion of conventional resources. Oily sludge is a hazardous waste inevitably …

In this study, the effect of four asphaltene samples on the wettability alteration of carbonate
reservoir rock is investigated. The wettability of each core, before and after the deposition of …

The injection performance of carbon dioxide (CO2) for oil recovery depends upon its
injection capability and the actual injection rate. The CO2–rock–water interaction could …

Several benefits of low salinity/engineered water injection (LSWI/EWI) have been reported in
the literature including its ability to increase oil recovery at low cost and with least …

Carbonates are characterized by low oil recovery due to their positive surface charge and
consequent high affinity to negatively charged crude oil, rendering them to a state of mixed …

The injection of engineered water to increase the oil recovery from carbonates is
increasingly becoming popular due to its reduced environmental impact and low cost of …

Several benefits of CO 2 injection are reported in the literature such as its ability to mitigate
greenhouse gas emissions and the increase in oil recovery at a low cost. However, the …

Surfactant-polymer (SP) flooding is considered an efficient technique to increase the
recovery of oil, especially from carbonates reservoirs, because of their complex nature. The …

Several core-flooding-based experimental studies demonstrated the effect of calcium and
magnesium ions and it is found that these hard ions have detrimental effects on oil recovery …
