Bio-Surfactant Breakthrough Unlocks 15% More Oil in Shale Wells

THE WOODLANDS, TX – May 20, 2026 – A year-long field trial in the heart of Texas's Delaware Basin has yielded remarkable results, demonstrating that a new generation of eco-friendly chemistry can significantly boost oil and gas production from shale wells. Locus Bio-Energy announced today that its SUSTAIN® biosurfactant treatment increased the Estimated Ultimate Recovery (EUR) of treated wells by over 15%, a figure that could reshape the economics of unconventional oil and gas extraction.

The controlled trial, conducted in the challenging Wolfcamp A formation, showed that wells treated with the biosurfactant produced approximately 20% more cumulative oil and 23% more cumulative gas over a 12-month period compared to identical, untreated offset wells. The results, which build on previously announced six-month data, provide compelling evidence that the performance gains are not just a short-term acceleration but a durable, long-term improvement in reservoir recovery.

The Science of Sustained Performance

At the heart of this success is the shift from conventional, synthetic oilfield chemicals to advanced, biologically derived surfactants. SUSTAIN® is a biosurfactant, a class of compounds produced by living microorganisms. Unlike their petrochemical-based predecessors, these molecules are uniquely suited for the complex geology of modern shale plays.

"Conventional surfactants were never designed for the pore networks we're working in today," said Megan Pearl, Vice President of Technology at Locus Fermentation Solutions, the parent company of Locus Bio-Energy. "SUSTAIN® was. When your chemistry matches the scale of the rock, you reach oil the reservoir wouldn't otherwise give up — and twelve months in, those wells are proving it."

The key to this performance lies in the ultra-small size of the biosurfactant's micelles, which are clusters of molecules that help mobilize oil. Research indicates these micelles are approximately 3-5 nanometers, small enough to penetrate the tight, complex nanopores of shale rock where significant amounts of oil remain trapped. By reducing interfacial tension and altering rock wettability, the biosurfactant helps hydrocarbons flow more freely from the reservoir into the wellbore.

Crucially, the 12-month data confirmed that the production uplift was sustained as the wells transitioned from their initial high-rate, fracture-dominated flow period to a longer-term, boundary-dominated flow. This is a critical distinction for reservoir engineers.

"During the early-time fracture-controlled flow period, treated wells exhibited a 20% oil-rate uplift," explained Marty Shumway, Senior Vice President at Locus Bio-Energy. "The most compelling story is what happened next. As the wells transitioned into boundary-dominated flow, rate separation held — proving this uplift is not simply accelerated production, but a fundamental improvement in incremental recovery versus un-treated wells."

Furthermore, the treatment requires no changes to standard completion designs, equipment, or field procedures. It is a "drop-in" additive to the frac fluid, allowing operators to leverage the technology without adding operational complexity or capital costs for new equipment.

A New Calculus for Well Economics

For oil and gas operators focused on maximizing returns in a volatile market, the financial implications of the trial are profound. The company reported that the incremental investment in the SUSTAIN® treatment paid for itself in under 30 days and delivered a 13-18X return on investment after 12 months.

This transforms chemistry from a necessary line-item expense in a well's completion budget into a powerful tool for driving asset value. "Operators measure the value of unconventional wells through EUR as it underpins revenue, reserves, and capital allocation decisions," Shumway noted. "A 15% increase can significantly improve well economics. Chemistry shifts from a cost in the completion budget to a high-leverage tool and driver of overall asset value."

Beyond the direct production gains, the trial also demonstrated significant operational cost savings. The treated wells showed a more than 17% lower water-oil ratio (WOR). Producing less water alongside the oil translates directly to lower lease operating expenses (LOE), as it reduces the costs associated with lifting, transporting, and disposing of produced water. Locus Bio-Energy estimates this improvement could save operators between $1 and $3 per barrel of oil produced. As the industry continues to exhaust its ability to find major efficiencies in drilling and mechanical completions, this focus on "chemical efficiency" represents a new frontier for optimization.

The ESG Equation: Greener Chemistry Meets Higher Yield

The breakthrough comes at a time when the energy industry faces unprecedented pressure from investors, regulators, and the public to improve its environmental performance. The use of biosurfactants aligns directly with these growing Environmental, Social, and Governance (ESG) demands.

Unlike many traditional surfactants derived from petroleum, biosurfactants are produced from renewable resources through fermentation. They are known for being highly biodegradable and having significantly lower toxicity. This "green chemistry" approach reduces the environmental risk profile of hydraulic fracturing operations, offering a safer alternative for both workers and the surrounding ecosystem.

This move toward more sustainable solutions is part of a broader industry trend. Companies like Huron Industries are also promoting plant-based surfactants, and major operators have initiated programs to reduce chemical use and adopt less toxic additives. The ability of SUSTAIN® to deliver superior economic and production results while also offering a more environmentally friendly profile creates a powerful value proposition. It allows operators to pursue sustainability goals not as a cost center, but as a direct contributor to operational excellence and profitability, helping to secure their social license to operate in an increasingly climate-conscious world.

From Promise to Proving Ground: The Path to Adoption

While the potential of biosurfactants has been known for years, their widespread adoption in the oilfield has been hampered by historically high production costs. Locus Bio-Energy claims to have solved this challenge with a patented, scalable fermentation process that makes its products cost-competitive with conventional chemicals. This ability to produce at scale is critical for meeting the potential demand from operators managing multi-well pads across vast basins.

The company's methodology of using industry-standard data providers like Enverus to compile and verify results, as seen in its six-month data release, helps build the credibility needed for widespread operator adoption. The successful 12-month trial in the Delaware Basin, one of the world's most active and challenging plays, serves as a powerful proving ground. The consistent performance improvements, now demonstrated across multiple U.S. basins, are positioning the technology as a reliable lever for operators to pull.

As the industry continues to push the boundaries of technology to extract resources more efficiently and responsibly, the sustained success of advanced chemical treatments like SUSTAIN® signals a pivotal shift. It suggests that the next great leap in shale productivity may not come from bigger pumps or longer laterals, but from the microscopic, biological agents unlocking more value from the rock itself.
