case studies for GreenZyme(r) Fluid Technology Applications
GreenZyme® Treatments Yield Additional 440,703 BOP in 6 Years For a Single Well, Venezuela
Operator, had many blocked, underperforming wells located around Lake Maracaibo. Oil Well was chosen to receive multiple treatments of GreenZyme EOR, to test whether the recovery factor would increase after each treatment. GreenZyme had already established success in single treatment applications, but prior to this pilot, no multiple applications of GreenZyme had been recorded in South America.
EEOR Success in Mann Field, Myanmar (SPE 144231)
Oil production increased in two test wells in a mature oil reservoir in Mann Field, Myanmar by successfully applying anenzyme-enhanced oil recovery (EEOR) process.

EOR Pilot Tests With Modified Enzyme in, Dagang Oilfield, China (SPE 107128)
One specific pilot test with modified enzyme had achieved additional oil production 22,869 bbl.
Academic studies
Enzymes have recently been considered as possible agents for enhanced oil recovery (EOR) acting at the liquid–solid interface. One way to assess this is via measuring the wettability of calcite surfaces, important for EOR methods in carbonaceous reservoirs. In the present work, we have experimentally investigated the effect of enzymes on the wettability of calcite mineral surfaces with oil–brine systems.
New Agent for Formation-Damage Mitigation in Heavy-Oil Reservoir: Mechanism and Application, China (SPE 112355)
After the biological enzyme solution extracts crude oil from the sand surface, GreenZyme® can make oil and sand flow separately, preventing the formation of mud cakes while improving the mobility of crude heavy oil.
Enzymes for Enhanced Oil Recovery (EOR), Norway
Oil entrapment is a result of complex interactions between viscous, gravity and capillary forces. Improving recovery from hydrocarbon fields typically involves altering the relative importance of the viscous and capillary forces. It was found that enzymes can change the adhesion behavior of the crude oil on glass surfaces from adhesion to non-adhesion when they are added to the brine solution
The experimental results confirm a considerable decrease in contact angle with enzyme solutions compared to an untreated brine. We have been investigating to what extent enzymes can change the wettability state of an oil reservoir formation and possibly lead to increased oil recovery by waterflooding SCA2009-28
