Customized treatment program increases safety and profitability–AssurEOR lin
Locus Bio-Energy Solutions has introduced a customizable treatment program, AssurEOR line, for use in upstream applications. The new products have shown effective at improving production and safety. The technology was a finalist in the World Oil Awards.
The AssurEOR line is recognized as one of the industry’s first treatment programs that offers financial benefits from use. In addition to best-in-class well maintenance, the products increase production and recoverable reserves—leading to improved profitability and the potential for tax benefits. The monetary gains and decreased safety concerns have skyrocketed demand across a multitude of basins, including Appalachia, Powder River and the Permian. Growing awareness has resulted in invitations for Locus Bio-Energy experts to present information on the technology through a variety of forums—from industry events and news articles to award submissions.
“To be successful as an industry, it is crucial that we find solutions which address both growing safety concerns and the rapidly declining production curves, and the AssurEOR products do just that,” said Gary West, senior vice president of business development for Locus Bio-Energy.
The AssurEOR line consists of AssurEOR FLOW treatments for paraffin dispersal and wellbore cleaning, and AssurEOR STIM treatments for enhanced oil recovery. All of the products were developed using non-bacterial, microbial-based formulations that are highly potent, yet non-toxic—making them safer alternatives to chemicals that provide even better results. The program utilizes Locus Bio-Energy’s unique fermentation process, allowing each treatment to be fully customized to specific regional and well characteristics which maximizes performance. The innovative approach and impressive production increases are gaining national recognition.
“We understand that each well has its own challenges, and our focus at Locus Bio-Energy is to provide safe solutions that are designed for specific well characteristics and improve production for users,” said West. “The growing industry recognition, especially from respected organizations like TPH, indicates we’ve found a disruptive approach that could be a true game-changer for the future of the energy sector.”
Prior to treatments, users are encouraged to send well samples to the Locus Bio-Energy lab for product testing and formulation tweaks—optimizing results. The personalized AssurEOR products are currently available for use in the Appalachian, Powder River and Permian basins.
AssurEOR FLOW™
Highly effective paraffin dispersal product，that also increases production by up to 50%
KEY FEATURES

- No shut-in time or nutrients pumped
- Refineries have processed hundreds of thousands of barrels of crude oil treated with AssurEOR FLOW, with no issues
BENEFITS
- Safely disperses paraffin from rods & tubing, and keeps it in suspension
- Improves the condition of flowlines & storage tanks
- Increases production and recoverable reserves
- Reduces operating costs
- Potentially qualifies your wells for Federal/State Enhanced Oil Recovery tax breaks or credits
An HSE-Friendly Solution
Locus Bio-Energy has developed a patent-pending paraffin treatment product specifically designed to remove paraffin buildup that stress mechanical components, reduce interfacial tension, and remove biofilms that clog channels. AssurEOR FLOW™ has been shown to increase production and recoverable reserves—so much so that treatments often pay for themselves. It is 100% biodegradable, non-toxic and is applied in the same manner as traditional treatments.
Multiple mechanisms of action
- Disperses paraffin by emulsification and bio-solvents generated during fermentation
- Keeps dispersed paraffin suspended in solution with bio-solvents and bio-surfactants
- Bio-surfactants penetrate into the paraffin, increasing surface area for dispersing
- No adverse impact on hydrocarbon profile or increase in acidity
Offers enhanced production effect not seen with other technologies
- Bio-surfactants reduce IFT and alter wettability of rock close to the wellbore to ease oil access and flow from pores
- With subsequent treatments, bio-surfactants can penetrate and act further into the formation
- Bio-chemicals created during fermentation lower viscosity of crude oil, enabling easier flow out of the pores
- Bio-chemicals created during fermentation progressively dissolve bio-polymers, such as polylactic acid (PLA) and guar, that might be blocking parts of the formation
No risk of corrosion
- As our biochemical product does not contain any bacteria, there is no risk of corrosion through the formation of corrosive biofilms
AssurEOR STIM™
Low-cost tertiary solution delivering，up to 500% increases in production
KEY FEATURES
- Bio-chemical-based formation level treatment
- Very short shut-in times
- No microbes used, nor are any nutrients injected
RESULTS & BENEFITS
- Substantially and consistently increases production
- Significantly increases recoverable reserves and asset value
- Does not cause corrosion or increase oil acidity
- Is effective in both horizontal and vertical wells across most formations, operating depths, permeabilities and porosities
- Potentially qualifies your wells for Federal/State Enhanced Oil Recovery tax breaks or credits
Cost Effective and High Efficiency
Locus Bio-Energy’s AssurEOR STIM™ Enhanced Oil Recovery solution fills a market need for a cost-effective and high-efficiency tertiary extraction method. It is highly potent and designed to treat the formation to help stimulate the reservoir for increased oil and gas production.
Thermal, gas and chemical (polymer) injection methods are extremely expensive and many are toxic, and traditional Microbial Enhanced Oil Recovery (MEOR) methods have not delivered upon expectations.
AssurEOR STIM™ treatments substantially increase production over extended periods—with wells treated in Summer 2017 still showing the increases in Spring 2018. This chart shows a typical treatment result. A 3800’ Clinton sandstone vertical well was treated with the AssurEOR STIM™, followed by a short 3 day shut-in. The net result of the treatment was a 300% increase in production over a period of 4 months.
Decreases IFT, surface tension and viscosity
Combination of bio-chemical surfactants allow for the reduction of interfacial tension (IFT) between oil and water, as well as reduction in oil viscosity allowing the oil to have increased mobility in the reservoir.
Bio-surfactants can decrease water surface tension from 72 dynes/cm to 28-30 dynes/cm at very low concentrations.
Wettability alteration of produced water
Efficient recovery of hydrocarbons from the produced water by altering wettability – helping water to imbibe from fractures into matrix blocks to displace oil out.
Wax and scale removal from formation
Disperse paraffin waxes and asphaltene deposits. Remove iron sulfide scale attached to the waxes to improve flow.
