DATA-DRIVEN ANALYSES OF LOW SALINITY WATERFLOODING IN CARBONATES

Salimova, Rashida (Nazarbayev University School of Mining and Geosciences, 2021-07)

Maximizing crude oil recovery is a main objective of the oil and gas industry. Oil recovery by natural production in carbonates is usually lower than 30%. Thus, Enhanced Oil Recovery (EOR) methods are used to increase the ...
IMPACT OF SO42−, CA2+, AND MG2+ IONS IN CASPIAN SEA ION-ENGINEERED WATER ON THE RATE OF WETTABILITY ALTERATION IN CARBONATES

Bazhanova, Meruyet; Pourafshary, Peyman (Journal of Petroleum Exploration and Production Technology, 2020-09-20)

Tuning the salinity and concentration of potential-determining ions, such as Mg2+, Ca2+, and SO4 2−, could alter the wettability toward a more water-wet state. The rate of alteration in carbonate rock wettability is a ...
