Microbial Enhanced Oil Recovery
Unlock reservoir value with beneficial in-situ microbes
Maximize oil production efficiently and sustainably with customized microbial solutions that enhance hydrocarbon recovery. By reducing viscosity and improving oil flow, MEOR can increase the yield from reservoirs while minimizing the need for additional chemicals or energy-intensive methods.
What is Microbial Enhanced
Oil Recovery?
MEOR is novel biological enhanced oil recovery technology for liquid-rich unconventional and conventional reservoirs that provides a quick response and lasting impact that improves production over the life of the well.
With MEOR, you can uplift production decline curve, increase proven development reserves, and ultimately achieve maximum return on investment by incorporating our proprietary microbial technologies to your integrated subsurface analysis systems and field development plan.
The Select Approach to MEOR
Traditionally, MEOR has occurred in the production phase of well operations, but Select implements MEOR in both the production and completion phases. Working in reverse from the frac location, we find one of the most important phases of treatment immediately prior to the frac, which is disinfection.
Water used during frac operations will be injected downhole, where microbes are at much higher concentrations and already adapted to the high-salinity formation. If deleterious microbes thrive in the reservoir, production can be harmed via plugging from biomass growth, fouling, corrosion (from acid formation), and formation of toxic gases like hydrogen sulfide (H2S).

Enhanced Oil Recovery
9-12% Incremental Reservoir Recovery
Lower Water Lifting Cost
Lower Oil Water Separation Cost
Steps to Subsurface Success
Customized nutrients are injected into the reservoir to activate the native subsurface beneficial microbes.
Microbial activity blocks the “Thief Zones” (highpermeable zones) and improves oil mobility.
Increased production and Proved Developed Reserves (PDP) while reducing water cut.
Success in both sandstone and carbonate reservoirs that are candidates for waterflooding.
Proven results at a minimum cost compared with chemical, thermal, and Gas EOR approaches.
Cutting Edge Research
Select’s understanding of downhole fluid chemistry is unparalleled. Our labs develop and deploy more custom FR and completion chemistry than any other industry supplier.
Select’s MEOR technology has established grant partnerships with US DOE and NSF as well research advancements with the University of Texas-Austin, University of Houston, and University of Calgary.
A Conventional Case Study
In an effort to explore regained conductivity of the damaged area, Select Chemistry developed a bioremediation method that was further validated by microfluidic testing. Modified nutrients were used to stimulate the indigenous nitrogen reducing bacteria that could consume or break the polymer residues.
