Petromin Resources report positive testing results from Chinese CBM project
Petromin Resources' (TSX.V: PTR) 30%-owned associate Terrawest Energy Corp (TWE) has reported positive results of gas desorption testing from its Coal Bed Methane (CBM) project in Xinjiang, China. Subsequently, the company believes that the project's two target formations each represent a viable CBM prospect on a stand-alone basis.
At the Liuhuanggou CBM project, TWE has been testing coal drill core samples taken from both the Xishanuyao (J2X) and Badaowan (J1B) formations during the company's 2009 drilling program. The LHG 09-03 well, at J2X, was drilled to total depth of 726 meters, intersecting over 50m of J2X coal. The subsequent CBM desorption testing results indicate that J2X has greater than anticipated gas content - ranging from 30.08 standard cubic feet (scf/ton) to 268.69scf/t, as calculated to the end of March 2010.
"The readings confirm the final desorption results from well LHG 08-01 which had shown higher gas content results for the J2X particularly the upper 4-5 and 9-10 seams where desorption results of 53.62 to 199.92scf/t and 53.74 to 243.32scf/t, respectively, were measured".
Furthermore the company said that the gas content results for the J2X are especially encouraging, when combined with the thickness of the coal seams - which average 25.74m
At the J1B formation coal samples taken from wells LHG 09-01 and LHG 09-02 indicate that the J1B coal is generally higher in gas content than at J2X - with the CBM content ranging from 105.98 to 335.43scf/t and 86.74 to 350.49scf/t respectively.
"Taken together, the total average net thickness of the two coal seam packages (44.9m or 148.7 feet) and the latest gas content results represent a unique CBM prospect in the world when compared with major CBM producing or exploration basins".
