The decline in oil production rate is a serious problem and has long been a drag on the oil and gas industry. The decline in oil production rate of which can be caused by a decrease in permeability around the wellbore due to damage. Basically stimulation operations intended to increase the production rate and or improve fluid movement can be taken in a reservoir. Performance of well JV #43 before and after GreenZyme stimulation Stimulation of wells can be done in two ways, na

The innovative technology is based on a water soluble inert liquid enzyme concentrate with unique properties to interact in a catalytic fashion with hydrocarbons. GreenZyme® is made using oil loving microbes where the oil digesting property is neutralized, and the ability to attach to and release hydrocarbons is kept. The enzymatic function of GreenZyme® is due to the fact that the enzymes seek and release the oil, however is NOT consumed in the releasing mechanism. After the

Introduction Recent studies have shown that water properties can be modified based on salt composition and concentration, resulting in increased oil recovery in comparison to conventional water flooding in which formation brine is injected. However, chemical surfactants present important challenges that need to be dealt with before using them. Hence, there has been an increased focus on studying biological surfactants as good substitutes for chemical surfactants in EOR proces

GreenZyme® implementation has very simple and cost effective steps. The fluid arrives in concentrate form to the field site.

Abstract: In this study, we investigate potential application of environment- friendly bio-surfactants (EFBS) in EOR processes. We assess the prospect of combining the EFBS with controlled salinity (CS) water injection in optimizing oil recovery using rhamnolipid and protein-enzyme as case study. Rock component analysis, bio-surfactant solubility in brine of varied concentration and composition, crude oil-brine interfacial tension (IFT) and bio-surfactants emulsification acti

GreenZyme® is completely mixable in produced water, it has been found effective in concentrations of 0.01% in academic studies, and still be productive in “releasing” crude oil from rock surfaces in the formation as it continuously diffuses in the reservoir. GreenZyme® is then an agent in combination or replacement of all secondary oil-recovery additives. As a non-chemical and non-reactant catalyst fluid, GreenZyme will continue to release crude oil from rock surfaces over ti

The conference held in Garden Grove, California on the 22nd April spanned across 4 days with great discussions, networking opportunities, and short courses. The theme of this event was Emerging Technologies for Maximizing Recoveries in California. The agenda included a variety of excellent papers and featured leaders of California's oil companies and reflective of California's production challenges. The SPE Western Region has a long history of heavy oil thermal recovery in Ca
