Talisman Energy Inc. has announced first oil production from its Hai Su Trang and Hai Su Den (HST/HSD) development, offshore Vietnam. Gross production is expected to reach 15,000 bbls/day once the facilities are fully commissioned. This development will help Talisman meet its regional and corporate objectives of adding near-term, high-margin liquids volumes and associated cash flow. In addition, it will allow to evaluate the further development potential of the HSD field. The HST/HSD development is comprised of two offshore oil fields discovered within Block 15-2/01, on the western edge of Vietnam's prolific Cuu Long Basin. Block 15-2/01 is operated by the Thang Long Joint Operating Company (TLJOC) in which Talisman (Vietnam 15-2/01) holds a 60% working interest and PVEP holds the remaining 40%. The development is located 75 kilometres offshore Southern Vietnam in shallow water (45 metres), and consists of two wellhead platforms which have been tied back to the existing Te Giac Trang FPSO. Four wells at HST have been drilled, completed and tied-in, and two previously drilled wells at HSD were completed and tied in by TLJOC, utilizing PV Drilling.
