AssurEOR programme selected as New Technology Development of the Year Finalist in Texas Oil & Gas Awards.

AssurEOR, a new green paraffin remediation and reservoir stimulation treatment programme from Locus Bio-Energy Solutions? (Locus Bio-Energy), has been selected as a finalist for the New Technology Development of the Year honour in the Texas Oil & Gas Awards.

The environmentally–friendly line of treatments, which won the category in the Northeast Oil & Gas Awards earlier this year, is being lauded as a truly novel oilfield chemistry that safely and cost-effectively maximises the performance of declining wells, reducing the need for new drilling to maintain production rates.

The AssurEOR programme has caught the attention of the industry for its use of the world’s most proven biosurfactants, previously only used in large volumes in personal care and high–end household cleaning products. Using patented modular fermentation technology, the company can economically manufacture these highly–effective, natural products at scale—bringing unsurpassed performance, sustainability and profitability to oil production. Each ultra-potent treatment is optimised to individual wells and offers benefits typically not achievable with traditional petrochemical surfactants, including successful paraffin remediation and well stimulation.

“Locus Bio-Energy’s AssurEOR programme has made tremendous strides in shifting the oil industry’s perception of green technology, proving—for perhaps the first time—that environmentally–friendly solutions can outperform, and be more cost effective, than the synthetic surfactants currently in use,” said Jonathan Rogers, the company’s CEO. “These treatments are enhancing production and extending the ultimate recoverable reserves of treated wells while moving the oil industry forward in innovation, environmental stewardship and social responsibility. We’re honoured that the importance of these advances has been recognised by the Texas Oil & Gas Awards judging panel.”

The customised biosurfactant treatment programme consists of two products—AssurEOR FLOW? for paraffin remediation and AssurEOR STIM? for well stimulation. When used together, the solutions naturally improve the economic viability of existing wells by offering significant increases in production rates and recoverable reserves. Since availability was expanded to Texas oil basins less than a year ago, interest has grown rapidly based on impressive ongoing results on over 100 Permian wells.

AssurEOR FLOW?

KEY FEATURES

Non-bacterial, and no possibility of forming corrosive bio-films 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

RESULTS & 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

In independent laboratory tests, Locus Bio-Energy Solutions’ AssurEOR FLOW remediation treatment exceeded the wax dispersion efficacy of Xylene and other solvents, significantly outperforming 3 competitive dispersant samples.

AssurEOR FLOW? Case History

A 70 well production case study in the Appalachian Basin confirmed paraffin dispersal, reduced LOE and consistent increases in production—consistent with what we are seeing with all customers.

The wells selected were a random mix of horizontal and vertical wells ranging in depth between 2000’ and 6000’ that were previously treated bimonthly with a mix of solvent and condensate. AssurEOR FLOW? treatments began in month 82, with the wells kept on the same bimonthly application schedule.

RESULTS SHOW

50% increase in production over the forecast production (shown in the decline curve) 15,369 barrels of incremental oil produced No well failures during length of the study due to paraffin accumulation

AssurEOR STIM?

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? Case History

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.

For best results, Locus Bio-Energy recommends 1-2 AssurEOR FLOW? paraffin dispersal treatments prior to the AssurEOR STIM? applications, to clean the well and increase responsiveness.
