The Jatayu-1 exploration well, located onshore Indonesia was suspended in September 2012 with the setting of 4.5" casing down to 6,640 feet measured depth. Approximately 200 feet of open hole section below the casing shoe and this section could not be evaluated by open hole logging before the well was suspended due to drilling difficulties experienced at the time.
Utilizing a slim hole rig, drilling recommenced on approximately December 12, 2012. Immediately upon drilling through the cement plug placed to suspend the well in September 2012, an influx of gas resulted in the implementation of well control procedures and 13.5 pound per gallon mud was required to kill the well indicating severe over pressure. The well has now been stabilized, however a detailed analysis of the drilling mud salinity before and after the gas influx indicated there was formation water present with the gas, strongly suggesting no commercial potential of the section drilled. Further, this severe overpressure, in combination with drilling fluid losses that were encountered in the drilling of the deeper open hole section in previous drilling, creates an unacceptable level of well control risk, particularly while utilizing the current slim hole drilling configuration. As a result, the well is currently being abandoned. The future course of action with regard to the Jatayu prospect will be determined sometime after the completion of drilling of Cataka-1A
Cataka-1A has been drilled to a measured depth of 1,692 feet (true vertical depth of 1,636 feet) and is currently being cased. Drilling is on plan and the difficult section encountered in the abandoned Cataka-1 well, has been successfully drilled in Catak1-1A. The primary objective of the well is expected to be encountered at a depth of approximately 7,325 feet measured depth.

The drilling of Shinta-1, the first of three back-to-back appraisal / exploration wells is anticipated to commence in late January to early February 2013. In addition to Shinta-1, Buana-1, an appraisal to the NTO-1 gas discovery, and Kemala-1, an exploration prospect, will be drilled. (end of excerpt)
