Fig. 7From: Microbial enhanced heavy crude oil recovery through biodegradation using bacterial isolates from an Omani oil fieldCumulative recovery factor versus injected PV using B. licheniformis AS5 isolate. WF recovered = 24.2 % of OIIP, BNF = 2.5 % of OIIP recovered. WF after 5 days of incubation of isolate B. licheniformis AS5 resulted in an additional 16 % recoveryBack to article page
