The AssurEOR STIM enhanced oil recovery (EOR) technology of Locus Bio-Energy has received ISO-14064 certification from SGS SA, which means the technology complies with global greenhouse gas standards.
The AssurEOR STIM biosurfactant technology reduces the carbon intensity and boosts production of crude oil and natural gas operations. It helps hydrocarbon companies and their clients to meet their decarbonization goals and “produce more with less resources”, the Ohio-based company said in a statement.
SGS is a Swiss multinational company that provides inspection, verification and testing certification services in over a dozen global industries. The ISO-14064 certification was developed to comply with both ISO 14064:2-2019, which lists reporting compliance for greenhouse gases, and the European Union Commission’s Innovation Fund Methodology for GHG Emission Avoidance. It allows for easy incorporation into scope and carbon intensity accounting, according to the statement.
The EOR technology has already been deployed successfully on hundreds of wells across key basins to address declining oil and gas extraction, Locus said, adding that the technology can help cut costs and increase revenue.
“Companies around the world that rely on oil and gas and its by-products are under tremendous pressure to meet their decarbonization goals; often with no clear path to do so in a meaningful manner”, Locus CEO Andrew Lefkowitz said in the statement. “There isn’t another technology that can immediately enhance extraction without additional CAPEX [capital expenditures], while also accelerating decarbonization progress”.
According to Locus Director of Marketing and PR Teresa DeJohn, the SGS certification was based on the actual historical performance of the technology. In a scenario comparing two wells, the one with EOR treatment showed a seven percent reduction in carbon intensity on a per-barrel basis across 10 years, along with a 10 percent overall boost in production. The second scenario looked at drilling and hydraulic fracturing, or fracking, were pulled back while maintaining production, which DeJohn noted was more relevant outside the USA where production allocations are common. The EOR treatments allowed operators to produce the allocated with less drilling, with the estimated impact for each well not drilled or fracked being a 20 percent reduction in carbon intensity per barrel, plus reductions in water, diesel, sand and chemical use, DeJohn said.
Credence Energy Services signed an agreement in December 2021 to become the exclusive distributor of the EOR treatment technology in the Williston Basin. According to the company’s CEO Kevin Black, “We’ve treated wells with Locus’ biosurfactant technology in the Williston basin for years, and feel that it’s playing a pivotal role in making the region a leader in sustainable oil production. Declining wells pose a significant challenge to overall oil production, especially within the tight formations common to [the] Bakken shale. After witnessing the impressive returns supplied by this EOR biosurfactant technology, we’re now treating at the beginning of the well life cycle to have a larger production impact”.
Utica Resource Selects Locus Surfactant
In July, Utica Resource Operating LLC selected Locus Bio-Energy® (Locus BE) to supply a novel, biosurfactant-based solution for a multi-well completion program in the Appalachian Basin. The results of Utica’s third-qualification testing showed that Locus’ Sustain SF101 biosurfactant-based hydraulic fracturing surfactant outperformed nine others based on cost and performance, Locus said in an earlier news release.
“We created the Sustain line of biosurfactants to help oil and gas operators essentially do more with less”, Locus Senior Vice President Marty Shumway said. “These third-party test results confirmed that SUSTAIN can do just that—deliver more oil with less chemical and cost while reducing [the] environmental footprint of the overall chemical program”.
“Using Sustain biosurfactant-based chemistries as part of Utica’s completion fluids will go a long way to build a better well”, Shumway added.
Utica Resource completed an 812-stage completion program on 11 wells using Sustain SF101. In addition, Locus Bio-Energy also provided ancillary chemicals for the program including a scale inhibitor and biocide, according to the release.
