Unlock Trapped Oil and Extend Production

Biosurfactant EOR solutions that mobilizes hydrocarbons in micro- and nanopores for sustained recovery

What Is AssurEOR STIM®?

AssurEOR STIM® is a biosurfactant-based enhanced oil recovery solution designed to mobilize hydrocarbons that remain trapped after primary and secondary recovery. It improves how fluids interact within the reservoir—enabling access to oil in micro- and nanopore structures and extending production beyond conventional limits.

Primary Applications

Enhanced Oil Recovery (EOR)
Mobilize trapped hydrocarbons and extend production from existing wells
Post-Frac Optimization
Access bypassed zones and improve recovery after initial completion
Mature & Conventional Wells
Increase recovery from depleted formations by mobilizing remaining oil
Chemical & Surfactant Flooding
Improve sweep efficiency and mobilize residual oil through enhanced fluid interactions and displacement control

Frequently Asked Questions

AssurEOR STIM® is a biosurfactant-based enhanced oil recovery (EOR) treatment designed to mobilize residual oil trapped in the reservoir.

It targets oil that conventional methods leave behind by:

  • Reducing interfacial tension between oil and water
  • Altering rock wettability to release trapped oil
  • Penetrating micro- and nanopores using nanoscale micelles

This allows access to oil that standard chemistry cannot reach.

Oil becomes trapped due to:

  • capillary forces
  • water blocking
  • oil-wet rock surfaces

AssurEOR STIM is designed specifically to overcome these physical barriers.

Conventional EOR:

  • Often relies on bulk fluid movement (water, gas, polymers)
  • Limited penetration into tight rock

AssurEOR STIM:

  • Works at the interfacial level
  • Accesses smaller pore spaces
  • Improves recovery without major infrastructure changes

Biosurfactants exhibit strong adsorption/desorption behavior, allowing treatments to continue working over extended periods.

  • Mature wells with declining production
  • Tight or unconventional reservoirs
  • Fields with significant residual oil saturation

Wells with minimal remaining movable oil or strong natural drive mechanisms may see limited uplift.
