[{"type":"text","content":"\n\n\n\n\n\nTORONTO, Jan. 7, 2013 /CNW/ - Sintana Energy Inc. (TSX-V: SNN) (\"Sintana\" or the \"Company\") announces that it has been notified by the Operator of the Talora Block, Petrodorado Energy Ltd. (TSX-V: PDQ) (\"Petrodorado\" or the \"Operator\"), that the Dorados-1X exploration well, which commenced drilling operations on July 31, 2012, has completed the previously reported flow test program. The Company has an undivided 30% private participation interest in the 58,570 acre Talora Block, which is located in Colombia's prolific Magdalena Basin.\nThe original planned total depth for the well by the Operator was 9,500 feet (MD) with the Cretaceous Caballos and Tetuan (Albian/Aptian) formations being the primary objectives. While drilling in the Cretaceous Cenomanian section above these objectives, the well encountered a younger and exceptionally thick sand-prone sequence which has never previously been reported in the basin. This sand-prone section, currently named the \"Dorados Sands,\" was encountered from about 5,160 feet (MD) to below 7,000 feet, or around 1,850 feet thick (gross). While drilling, this section (5,160 to 6,035 feet) yielded excellent wet gas and oil shows as measured by both Gas Chromatography and Mass Spectroscopy. The Economic basement was reached much higher than the prognosis at 7,282 feet (MD), without seeing the Tetuan or Caballos formations and as such, the partnership decided to terminate drilling operations at this depth on September 29, 2012 with the forward plan to log and then production test the extensive \"Dorados Sands.\" \nDue to the deteriorating hole conditions, tool sticking and high levels of mud invasion (7 lost circulation events) it was operationally impossible to run an adequate logging program. With limited data, however, it was noted that the targeted reservoir section coincides with the highest log resistivities (through casing logs), including zones with fair to good porosities (e.g. 15%). All these indicators, log resistivities, oil shows, hydrocarbon components (C1 through C9), hydrocarbon ratios, helium and other trace element relationships are all consistent with a thick hydrocarbon column. In addition, and very importantly, all these indicators terminate abruptly, still within the sand-prone section, at around 6,030 to 6,050 feet (as stated above), forming compelling ev...
