Otto Energy Continues Galoc-5H Well Drilling (Philippines)

Otto Energy Limited, as operator of the producing Galoc oilfield joint venture offshore the Philippines, provides the following update on the Galoc-5H and Galoc-6H drilling campaign in SC14C, part of the Galoc Phase II development approved in 2012.

During the period from 0600 hours (AWST) on 28 August 2013 to 0600 hours (AWST) on 4 September 2013, drilled the G-5H well 8½” hole horizontally from 2,700 metres to 3,526 metres. Results obtained from drilling logs indicate that the well is delivering in line with the pre-drill prognosis.

The forward plan is to continue drilling the G-5H well 8½” hole horizontally through the reservoir interval and run the completion liner and assembly.

Location and Proposed Depth

The Galoc field is located in Service Contract SC14C (Galoc Sub Block) in 290 metres of water approximately 65km North West of Palawan Island and 350km south of Manila in the Republic of the Philippines. The Galoc-5H and Galoc-6H development wells are being drilled within the existing producing field that has delivered over 10 MMbbls of production since the field was commissioned in 2008.

The Galoc-5H and Galoc-6H development wells will be drilled to a total vertical depth of 2,190 metres with approximately 2,000 metres 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 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 in November 2013.
