Enhanced Oil Recovery
Recover More Oil From Existing Wells
Unlock residual oil and extend production from mature wells
Results from the Bakken
Conventional enhanced oil recovery (EOR) methods leave significant oil behind in tight pore networks. Locus Bio-Energy’s line of biosurfactant based EOR solutions enable deeper reservoir access and mobilize trapped hydrocarbons, improving oil recovery and extending production from existing wells. AssurEOR STIM® targets deeper reservoir penetration and sustained recovery, while AssurEOR FLOW™ improves near-wellbore cleanup and flow to maximize early production.
Why conventional EOR falls short
A significant portion of hydrocarbons remains unrecovered after primary and secondary recovery. As reservoirs mature, remaining hydrocarbons are increasingly confined to smaller pore spaces where capillary forces restrict flow. Conventional EOR methods struggle to access these zones, leaving recovery potential unrealized and production in decline.
How biosurfactants improve enhanced oil recovery
Biosurfactants operate at the nanoscale, forming ultra-small micelles (3–5 nm) that penetrate smaller pore spaces within the reservoir. By reducing interfacial tension and altering wettability at this scale, they mobilize trapped hydrocarbons and enable flow beyond the reach of conventional chemistry.
Nanopore penetration
Accesses pore structures conventional surfactants cannot reach
Interfacial tension reduction
Releases hydrocarbons held in pore throats and improves early-time oil response
Capillary pressure reduction
Overcomes trapping forces that suppress long-term recovery
Wettability modification
Shifts mixed-wet rock toward water-wet conditions for improved mobility
Production-proven EOR performance
- Increased oil rates and faster uplift
- Dispersion of organic deposits to improve hydrocarbon mobility and flow paths
- Mobilization of residual oil in tight or depleted formations
- Sustained production uplift over time
- Higher EUR and stronger asset valuation
AssurEOR STIM®
Recover oil conventional methods leave behind
Biosurfactant EOR solutions that alters wettability and mobilizes trapped hydrocarbons to increase recovery from mature reservoirs.
AssurEOR FLOW®
Restore Flow. Unlock Early Production.
AssurEOR FLOW® restores near-wellbore permeability by dispersing paraffin, asphaltene, and other organic films that restrict flow.
