Operations Update - Indonesia

Sound Oil, the upstream oil and gas company with assets in Italy and Indonesia, is pleased to announce the following update on its operations in Indonesia.

Bangkanai PSC (Sound 5%):

Operations to drill four development wells on the Kerendan gas field in Kalimantan are progressing well.  The first well (K-4) has completed drilling and setting of casing in the uphole section, consistent with the schedule.  The rig has now skidded to the second location (K-6) to drill the corresponding uphole section.  Three of the wells will be batch drilled and the fourth will be drilled as a single operation.  Each well will be drilled as a deviated hole from the Sungai Lahei well pad located immediately west of the field.

Sound Oil's share of proved and probable reserves (proved undeveloped) in the Kerendan field are 6.685 Bscf and 0.070 MMbo (condensate) (Fugro Robertson CPR, October 2011); equivalent to 1.184 Mmboe.  The estimated NPV10 of the field to Sound Oil is some US$ 6.4 million.
