RNS Number:5439W Sound Oil PLC 14 May 2007 14 May 2007 SOUND OIL PLC INCIDENT AT PASUNDAN-1 DRILLING SITE Sound Oil plc (AIM:SOU) is a participant (through its wholly owned subsidiary Mitra Energia Citarum Limited) as a 20% shareholder in BPREC, the operating company (the "Operator") that is drilling the Pasundan-1 exploration well, located approximately 50 km southeast of Jakarta, Java, Indonesia. On 12 May 2007 at 0645 (Indonesian Western Time, 0030 BST) an incident occurred on the Pasundan-1 drilling rig that led to cessation of drilling activities. While operating below the 30-inch conductor, damage occurred to surface facilities of the rig caused by uncontrolled movement of equipment. There were no injuries to any personnel on the rig or the wellsite, downhole conditions remained stable and there was no impact on the environment. Currently the Operator is dealing with the incident according to its agreed accident investigation procedures and is preparing the necessary report to BPMigas, the regulatory authority. A full inspection of the damage to the rig and an estimate of repairs are being undertaken. The Operator's preliminary estimate is that repairs will take approximately 10 days. During this period BPREC will not be liable for rig contract costs. Gerry Orbell, Chairman of Sound Oil commented, "This incident is an unfortunate start to the drilling of Pasundan No 1 but at least no one was hurt. Apart from the delay, the incremental cost of this incident to Sound Oil is expected to be minimal".
