MEOR generally improves oil production but the increment may not justify the investment.
Therefore, we provide a brief economical assessment at the end of this chapter. Because it is inevitable to characterize the microbial community of an oilfield that should be treated using MEOR techniques, we describe three complementary start-up approaches.
These are: i culturing methods, ii the characterization of microbial communities and possible bio-geochemical pathways by using molecular biology methods, and iii interfacial tension measurements.

The changes include a new, responsive design featuring extended-hours data and more news. The last is called selective plugging.
Rock this far underground is often porous, full of tiny holes into which oil can flow. Microorganisms are selected for their ability to produce exopolysaccharides, evolved to keep them from drying out.

They become "waterproof" in a sense, and are directed to block those tiny holes, leaving the oil nowhere to go but up. The key to microbial enhanced oil recovery research is designing microorganisms that will best direct oil upward. Those that can withstand extremely high temperatures and produce the right sorts of substances are rarely found in nature.
This is where genetic engineering comes in: combining genes to create microorganisms that can work effectively in harsh underground conditions and subsist on inexpensive nutrients. The elephant in the room is the environment.
