This is a review of recent published papers regarding the theory of abiogenic origin of petroleum such as Kutcherov and Krayushkin (2010) “Deep-seated abiogenic origin of petroleum.” It discusses the overview of the theory and its credibility with various geological evidences, such as the presence of liquid oil and hydrocarbon gas in primary fluid inclusions in mantle derived rocks, existence of 496 basement oil and gas fields in 29 countries, and oil discoveries at ultra-deep hot temperature reservoirs.Experimental abiogenic hydrocarbon generation by CaCO3-FeO-H2O system at upper mantle ultra-high pressure condition has once been proven by several Russian and Ukrainian academic teams, such as Kenny et al. (2002). And its credibility was reconfirmed by several American academic teams such as Scott et al. (2004) during the last decade.The theory has already been applied to actual oil exploration. The Ukrainian Academy of Science achieved an extremely high success ratio of 57% through actual oil exploration with the abiogenic theory by 1990's. The exploration area in Dnieper-Donets Basin, Ukraine, had been disqualified as a prospect for a long time, due to the absence of source rocks. However, over 50 oil and gas fields have been discovered in Precambrian crystalline basement rocks and Paleozoic sedimentary rocks in the area so far.Practical applications of the abiogenic theory in explorations like the case of the Ukrinian Academy of Science are seldom performed in the world. However, the author sees that the said theory will soon be cognized as a highly effective exploration guide among oil exploration geologists.

A future pipeline project that will transport crude oils from East Siberian fields to Nakhodka, shipping port along the coast of the Japan Sea, is under discussion and gradually revealing its main framework. One of the major concerns is if significant potential of petroleum is expected in the East Siberian region. In this paper, the total of the original oil resources in the region is estimated ranging from 18.9BBO (billion barrel of crude oil) to 67.2BBO.The Siberian platform is consisted of largely uplifted Archean crystalline basement and the overlaid sediments consisted of the Proterozoic and the Lowest Paleozoic formations. Most of the known oil reserves (85%) in the East Siberian region concentrate on the crest of the highest basement uplift on the two arch structures ; Baykit and Nepa-Botuoba. Petroleum source rocks are not concluded yet. Although the Riphean is expected to contain source rocks, it is entirely absent on the most prolific Nepa-Botuoba Arch area. Moreover, most fields have extremely high helium content (ranging 0.2-0.6 percent) with hydrocarbon gases. Based on several unique characteristics of oil and gas fields on the Nepa-Botuoba Arch, the author proposes in this paper that the theory of abiogenic origin can not be ignored ; hydrocarbons associated with helium gases may have migrated upward through the fractures from the depth of the earth.Upon completion of the pipeline linking the supply area (East Siberia) to the market in the Pacific region, oil exploration activities will be accelerated in the East Siberian region. Subsequently, the additional oils derived from the new discoveries in the East Siberian region will fulfill the new pipeline.
