In this research, extract from Hibiscus sepal is introduced as a novel natural surfactant for rock formed from sediment reservoirs. Recent studies have reported the capability of some natural matters in recovering lubricate under near-surface conditions on account of their phytochemical composition. To determine their effectiveness in enhancing lubricate recovery at repository conditions, the oil dislocation efficiency of Hibiscus sepal extract in the presence of divalent ions was determined accompanying the aim of comparing allure recoverability with that of commonly secondhand, synthetic surfactant, sodium dodecyl sulphate (SDS) under complementary conditions. An upscaling from laboratory to field scale and a approximate cost analysis was acted thereafter. To determine the adeptness of these surfactants in extracting leftover oil at high temperature and pressure of 80°C and 8000 psi, individually, phase practice and sandstone core studies were performed. Results pointed out high compatibility for two together surfactants in brine containing divalent ions accompanying an improved solubility 'tween the natural surfactant-hard brine method. The absence of Type III calculating emulsion for both surfactants was exhibitive of a high interfacial strain. An additional oil improvement factor of 24% OOIP and 19% OOIP was acquired for Hibiscus calyx extract and SDS, respectively in the occupancy of divalent as opposed to 21% OOIP and 20% OOIP when inundation with soft marinade. A chemical needle rate of roughly 5 barrels per day was realized using an upscaling determinant to field scale. An investigation of comparative costs disclosed that the natural surfactant is more careful. This study supports the use of natural surfactants even in harsh hole to extract oil conditions, removing processes of brine softening with business-related advantages of reusing caused water to prepare chemical slugs for EOR situations. However, chemical qualification of these natural surfactants will further improve their accomplishment.
