Bug flood - cheap reserve adds

flowery woman attracting beesRegulatory applications are leading indicators of oil and gas activity. Appintel is the easiest way to keep up with trends like microbial flooding.

How would you even find information on field trials of microbial EOR without AppIntel? With AppIntel AI simply type into the KiP omnibox  Show me microbial EOR .

Bio water diversion

The promise of microbial flooding is inexpensive water channeling control. No diversion chemicals such as polymer need be injected.

Instead of polymer, a small amount of nutrient is added to a fresh water injectant base. The microbes already in-situ will on the nutrient, grow and block water channels in the pool. As water channels rich with nutrient become plugged, water will be forced into unswept pore channels increasing sweep and recovery.

Microbial floods promise very cheap reserve adds by shutting off water channeling in mature water floods. This operator explains the microbe flood idea in depth in his application.

Look at the production response yourself

This microbial flood has been operating in Alberta for some time. In the flood, the operator injects bug food to feed the microbes that he believes already exist in the formation.

Among other things, the accelerated microbe growth causes high permeability streaks to become congested. This reroutes injectant into unswept portions of the reservoir. The promise is great increases to sweep efficiency.

Since the flood has been running for a few years, you can check out the impact on actual production. You can review the production profiles of the injection pattern identified by UWI in the application. This gives you more intelligence even than from SPE papers -- you can actually check out the enduring production gains by reviewing the flood's production response yourself.

It's all in the food you inject

microbes under electron scanning microscopeOf course, you need to be careful which what microbes you inject into the formation. If you inject foreign microbes (that are everywhere) you disturb the balance and may not be supplying the correct food. Operators often inject biocide (bleach) to prevent microbe growth in the wellbore perforations.

In a bug flood you can't just kill all the microbes in the injectant with biocide. If there's any trace of active biocide left in the injectant it will kill the in-situ microbes too.

Supplemental Information Requests -- illuminating discussions

The supplemental information requests (SIR) in this application are very instructive. The regulator has similar concerns to what you might have. The operator answered questions such as injectant composition and interaction with water chemistry.

SIRs document discussion and negotiation of many technical and stake holder issues. The regulator demands data and you get much more information from them.

By reading SIRs you can discover the issues the regulator considers important. From the discussion, you can see what satisfies the regulator and what type of answers don't please them.

Check out SIRs, cheap and cheery.
