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.
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.
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.
Accesses pore structures conventional surfactants cannot reach
Releases hydrocarbons held in pore throats and improves early-time oil response
Overcomes trapping forces that suppress long-term recovery
Shifts mixed-wet rock toward water-wet conditions for improved mobility
Biosurfactant EOR solutions that alters wettability and mobilizes trapped hydrocarbons to increase recovery from mature reservoirs.
AssurEOR FLOW® restores near-wellbore permeability by dispersing paraffin, asphaltene, and other organic films that restrict flow.
Mobilize trapped hydrocarbons and recover more from mature assets.
