Drilling Underway at Galoc Phase II Project

Otto Energy Limited (Otto), the operator of the producing Galoc oilfield joint venture offshore the Philippines, reported that drilling has begun at the Galoc-5H and Galoc-6H wells in Service Contract SC14C as part of the Galoc Phase II development approved in 2012.

During the period from 1300 hours (Australian Western Standard Time) June 4 to 0600 hours (AWST) June 12, the 36-inch (914 millimeter) hole was drilled to 1,312 feet (400 meters) on G-6H and the 26-inch (660 millimeter) hole was drilled to 1,312 feet (400 meters) on G-5H.

The forward plan is to set the 30-inch (762 millimeter) conductor on G-6H and open the G-5H hole to 36 inch (914 millimeter) and set the 30-inch conductor also prior to drilling the 17.5-inch (444 millimeter) hole to 3,117 feet (950 meters) on both wells.

The Galoc-5H and Galoc-6H development wells are being drilled within the existing producing field that has delivered over 10 million barrels of production since the field was commissioned in 2008.

The wells are being batch drilled in 1,020 feet (311 meters) of water. It is planned that the Galoc-5H and Galoc-6H development wells will be drilled to a total vertical depth of 7,185 feet (2,190 meters) with approximately 6,561 feet (2,000 meters) of horizontal completion. Drilling is expected to take approximately 115 days including the flowing of the wells for clean-up.

After drilling of both Galoc-5H and Galoc-6H by Ocean Patriot (mid water semisub) is completed, the DOF operated Skandia Hercules construction vessel will be used to install the subsea equipment and complete the hook-up of both wells to the FPSO Rubicon Intrepid.

First oil from the Phase II wells is expected during 4Q 2013.
