This study reports the extraction and performance evaluation of two bio-derived polymers for enhanced oil recovery applications. The oil displacement processes were conducted using six (6) unconsolidated sandstone core plugs. Reservoir permeability tester was used to simulate real reservoir conditions in order to evaluate the suitability of the formulated biopolymers for oil displacement applications at laboratory conditions. The experimental results indicate the effectiveness of the biopolymer solutions in enhanced oil recovery in terms of their superior incremental oil recoveries after conventional waterflood with percentage oil recovery of 30.9–39.3% for banana peel derived polymer and 40.6–50.8% for mango kernel derived polymer compared to conventional waterflood with percentage recovery of 16.2–32% of the initial oil in place. This work identified the potential suitability and use of bio-derived polymers for enhanced oil recovery applications with emphasis on their biodegradability.

这项研究报告了两种生物衍生聚合物的提取和性能评估，以提高采油率。使用六（6）个未固结的砂岩岩心塞进行驱油过程。为了评估配制的生物聚合物在实验室条件下用于驱油的适用性，使用储层渗透率测试仪模拟真实的储层条件。实验结果表明，生物聚合物溶液在常规注水后具有优异的增量采收率，因此提高了原油采收率，香蕉皮衍生聚合物的采收率分别为30.9％至39.3％，芒果仁衍生聚合物的采收率为40.6％至50.8％。与常规注水相比，采收率达到初始采油量的16.2–32％。
