Microbial enhanced oil recovery (MEOR) · Stripper, marginal, fracked and heavy-oil wells

Fix the Wellbore’s Biochemistry. Restore the Well’s Profit.

Seven root causes drive up lifting costs and cut production. They start downhole, where the oil’s chemistry meets the well’s biology, and they keep coming back because the usual fixes remove only what has already formed. Microbial treatment (MEOR) works on them where they start: no acid, no heat, no upfront capital.

Safer for crews and the lease: no acid and no heat in the program, fewer hot-oil, acid and solvent jobs, and BioActive reports less H₂S where people work.

Lower lifting costs. More years of profit.

Proforma example: a 1.5 BOPD stripper well with $1,200 a month in lifting costs and $60/bbl oil, with and without MEOR.

  • −13%lifting cost per barrel$26.67 → $23.33, treatment included
  • +39%net profit per well$933 → $1,300 a month
  • +9 yearsof profitable life8 → 17 years for a treated well

Each $300 monthly treatment brings back $667 in LOE savings and extra oil. Illustrative values, not a forecast for any specific well. Run your own numbers in the Stripper Well Profitability Calculator.

Stripper and marginal wells

Before you plug it, treat the cause.

Keep stripper wells profitable longer. When a well is plugged, its remaining oil is usually lost for good, and the plugging bill comes due with no revenue left to pay for it.

The scale

78% of U.S. producing wells are marginal

About 716,000 wells make 15 barrels of oil equivalent a day or less (EIA, 2024). The low end runs out of profit first, and that is where plugging liabilities pile up.

The squeeze

Lifting costs rise as production falls

Paraffin, H₂S, iron sulfide, asphaltenes, scale and corrosion add hot-oil and solvent jobs, scavenger and acid treatments, cleanouts, pump pulls and downtime, until the oil sold no longer covers the monthly LOE.

The way out

Treating the cause moves the economic limit

A lower cost per barrel and a lower break-even price keep a well out of the plugging queue. In the proforma, the treated well stays profitable for 17 years instead of 8.

“Low-rate wells are often one problem away from being shut in.”

Laura Freeman, Journal of Petroleum Technology, 2021

  • About $20 billion of plugging liability sits on roughly 770,000 U.S. marginal wells, at $25,000 a well, by the article’s count.
  • Overhead and costly workovers tip them over. A 5-barrel-a-day well can carry $2,500 a month in operating costs, the article shows, but not even $800 a month of added overhead.
  • Treating the cause takes the problem off the list. Fewer hot-oil and acid jobs, pump pulls and cleanouts mean fewer of the failures that push a low-rate well into the plugging queue.

Investors and non-operating owners

More profit from wells you already own

Microbial treatment works on existing wells, so the return comes without drilling, new equipment or upfront capital.

Cash flow

It adds up across a lease

Ten wells at the proforma’s numbers add about $44,000 of net profit in year one, and the gap widens every year as untreated wells decline faster.

Liability

The plugging bill moves out

A lower break-even keeps wells producing longer: 17 profitable years instead of 8 in the proforma, with the plugging cost pushed back by the same years.

Diligence

A pilot is the proof

Three to ten wells, measured against documented costs as net value, before any decision about the rest of the lease.
