Abstract

A wellbore method which, in certain aspects, includes providing with a primary system a fluid with microorganisms, the primary system including introduction apparatus, with the introduction apparatus introducing the fluid with microorganisms into an earth formation bearing hydrocarbons, the microorganisms for facilitating removal of the hyrdrocarbons from the earth formation bearing hydrocarbons, effecting heat exchange between the fluid with microorganisms and heat transfer fluid that has traversed an earth loop of an earth loop heat exchange system, the earth loop heat exchange system with an earth loop extending from an earth surface down into the earth with the heat transfer fluid flowable through the earth loop and heat transfer apparatus for transferring heat between the fluid with the microorganisms and the heat transfer fluid; and, in certain asepcts wherein effecting the heat exchange between said fluid with microorganisms and the heat transfer fluid prolongs life of and/or enhances activity of the microorganisms.
