THE CHALLENGE OF THE USE THE MICROORGANISMS IN ENHANCE OIL RECOVER

Authored by Santos SN

Energy is the key to the development of any society. Energy sources derived from fossil fuels are still hold the largest share of energy generation for society. So far, there are no many options for renewable sources and/or large-scale green products for total replacement of this source.The produce from these resources by currently used methods leads to only 8-50% recovery of the total oil present in the reservoir. There is a great need of efficient advanced methods of recovery of fossil fuel, to improve upon the recovery of trapped crude oil, which becomes inaccessible by traditional techniques. Conventional oil production occurs in three stages: Primary oil recovery is the result of natural internal reservoir pressure which exists within the formation, harvests only 30-40% of the original oil in place (OOIP) Patel et al.. When this internal driving force diminishes to a point at which oil production decline, then secondary recovery methods follow in the form of water flooding, which continues until the ration of oil produced to water injected yields more water than oil, after which the process becomes uneconomical to separate oil from the oil - water mixture. Enhanced recovery methods include the introduction of fluids to physically displace the OOPI to make it easier to recovery. It is estimated such secondary recovery methods will recoup about 15-25% of the OOIP Belyaev et al., Lazar et al., McInerney et al. ; Van Hamme et al., Patel et al. 2015. This residual oil is usually the target of many enhanced oil recovery technology and it amounts to about 2-4 trillions barrels Hall et al.,. Around 67% of the total oil reserves Bryant et al. The tertiary recovery methods involving chemical or thermal energy, which chemical flooding includes use of alkaline water floods, carbon dioxide flooding, and polymer flooding? Thermal recovery includes in situ combustion and the injection of steam. But all these recovery methods suffer from technological problems and money constraints.
