A geomechanical analysis further indicated a localized subsidence of approximately 0.3 feet at the injection site, emphasizing the need to monitor formation stability. This study highlights the critical role...

... Abstract This study aims to assess the foamability and foam stability of synthetic zwitterionic surfactants in a seawater environment, both in the absence and presence of oil. The primary objective is to determine their potential use in enhanced oil recovery (EOR) and CO 2 sequestration within...
