Flooding with microbes

Watching AER applications keeps you abreast of the latest oil and gas technology. And AppIntel is the easiest way to keep up with these trends.

A 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.

Microbes dig oil out of the smallest places

But microbial flooding also has microscopic advantages as well as macroscopic ones. As the microbes grow they are attracted to oil droplets in the unaccessible nooks and crannies of pore spaces. This operator believes that this attraction helps liberate unswept oil at a microscopic level. He even has pictures to prove it.

Several important risks are detailed in the application as well as some screening criteria. Even more important, since the flood has been running for some time, you can check out the impact on actual production. You can check the production profiles of the injection pattern identified by UWI in the application.

Microbes are everywhere

Microbes are everywhere. Apparently only 10% of the cells in your body are human -- many of the rest are microbes. Most of these microbes are beneficial to your health. They aid in digestion, immunity and healing.

Microbes exist on and in the earth as well. The theory: feeding the right microbes can help in oil recovery. There's an interesting primer on MEOR (microbial enhanced oil recovery) in the application. We found this information using AppIntel.

Each AER application contains your neighbor's perspective on the exploitation of oil and gas formations. Applications contain more exploitation ideas than you can even find in SPE papers.

Would you like to see what other operators in your areas are thinking about seismic, multifractured wells, polymer schemes and recovery? AppIntel can help.
