Azabache Energy Inc. announced that is has completed the workover of its OAx-1 well. The results of the a 12-hour test on the Lajas Formation yielded 7,000 m3/d (250,000 ft3/d) of natural gas at a wellhead pressure of 1.4 kg/cm2 with a 16 mm (64 inch) choke. The well is now under long-term test. Due to the poor casing conditions of this old well, the OAx-1 well will not be a candidate for stimulation but the long-term test could confirm a new area of gas development within the Covunco Norte-Sur block. Also, the company announces that it expects to begin drilling its CVOx-2 well by the end of this week. The exploration well targets the Vaca Muerta Shale and also a former gas discovery in the Tordillo Formation to a total depth of 2,100 meters (6,900 feet). It is expected that it will be completed and partially tested by the beginning of June. The fracture job in the shale should be designed and executed within three months of completion. The company expects to acquire significant new technical information concerning the Vaca Muerta shale during the drilling. This well will be the first exploration of Vaca Muerta shale in this portion of the basin.
