The work of Sheehy concentrated on the enhancement of oil recovery from a reservoir using microorganisms, and led to the patent, Oil Recovery Using Microorganisms [24], The main idea was to use a biocide to selectively kill certain microorganisms and then induce the growth of others by carefully controlled nutritional conditions. This idea has potential for some other applications and could be extrapolated to in situ refining. 

A disadvantage of injecting microorganisms employed in this patent is that they may occlude the reservoir pores. Further, these microbial cells may also find it difficult to diffuse into the small pores of the rock. The method involved in the present invention deals with the native bacterial population of the well. A biocide is applied so that
