Abstarct: This study was carried out aims to explore unconventional hydrocarbon resources by methods of organic geochemistry. Shales Gas due to high organic matter if the maturity of organic matter into gas window and dry gas production and gas formation takes place in their, as shale gas (unconventional reservoirs) is considered that today in developed countries have reached the stage of production. The exact amount of gas shales reserve in the world is unknown, but estimates show that western australia has huge reserves of gas continues. According to the Energy Information Administration of America in 2011, Australia is the sixth largest country in terms of reserves of gas shales. Therefore, evaluating the production potential in unconventional reservoirs including research interest in the oil industry. In this study, was discussed organic geochemical properties in Canning Basin formations of Western Australia. For this purpose, the characteristics of Barnett shale (as a shale producer and importance in the United States) a set of geochemical parameters formations of interest were determined in the Canning basin of Western Australia and their values were compared with the values of the minimum threshold in the Shale Barnett. Evaluation reflection coefficient Vitrinite, the maturity of the samples and to examine the possibility of shale gas potential. Results of the TR-Ro charts, baxsed on the maximum and minimum Ro, is evaluated gas productions from kerogen of source rock and petroleum cracking. According to studies conducted by analysis of rock Eval and geochemical logs, three formations consist of Goldwyer, Noonkanbah and Poole are production potential of hydrocarbons. According to the calculations, total hydrocarbons that constructive in Goldwyer, Noonkanbah and Poole formations equal to 877/34, 315/94, 183/34 (bcf / section) (amount of produced oil and gas for Goldwyer 702, 175/34, Noonkanbah 224/32, 91/62 and Poole 132, 51/34 bcf / section), and the total gas formations preserved in Goldwyer, Noonkanbah and Poole formations, respectively 202, 78/80 and 45/34 (bcf / section) is according to the thickness of this formations amount of gas maintained can be compared Barnett shale impressive. At the end of a series of additional analyzes, were used including gas chromatography (GC) and star diagrams (techniques for the characterization of oils in organic geochemistry).
