On October 31, 2001, Trinidad and Tobago's Ministry of Energy and Energy Industries announced it had awarded exploration Block 3(a) to a consortium that includes BHP Billiton, Talisman Energy, BG International, and TotalFinaElf. The award is subject to final negotiation and execution of a Production Sharing Contract with the Government of Trinidad and Tobago.
Comprising about 150,000 acres (237 square miles), Block 3(a) is located 25 miles off the northeastern coast of Trinidad in 100 to 300 feet of water. BHP Billiton is the designated operator and holds a 30 percent working interest. Talisman Energy and BG International each hold a 30 percent interest and TotalFinaElf S.A. holds the remaining 10 percent equity.
Block 3(a) will substantially enhance BHP Billiton's acreage position and is located adjacent to Blocks 2(ab) and 2(c), where the Group has participated in five exploration wells and announced three hydrocarbon discoveries in the past two years.
The Angostura gas discovery [Block 2(c)] made in 1999, tested natural gas at a stabilized flowrate of 30 million standard cubic feet per day (mmscfd) through a 56/64 inch choke. The Aripo gas discovery [Block 2(c)] in 2000, tested natural gas at a stabilized flow rate of 21.6 mmscfd through a 44/64 inch choke (maximum 46.3 mmscfd via a 80/64 inch choke).
Another exploration well in Block 2(c), Kairi-1, encountered both oil and gas in a hydrocarbon column that included 322 feet of net gas pay and 235 feet of net oil pay, and tested 3,000 barrels of oil per day through a 38/64 inch choke from 14 feet of perforations.
BHP Billiton is currently drilling Canteen-1 well on Block 2(c), located one mile to the north of Kiari-1, using the jack-up rig Global Marine Labrador 1 . The well was spudded on October 23, 2001 in a water depth of 164 feet and has encountered hydrocarbon bearing sands, further supporting the oil and gas potential found in Kiari–1.
Drilling is expected to be completed in the next few weeks, and the final results will be used to evaluate the size of the discovery and development planning options. BHP Billiton holds a 45 percent operating interest in Block 2(c).
President and Chief Executive Officer BHP Billiton Petroleum Philip Aiken said: "Trinidad is quickly becoming another core growth area for the Group. Award of Block 3(a) and the results from drilling on Block 2(c) provide significant encouragement for potential oil and gas production."
"We are creating shareholder value by our focused exploration efforts and by acquiring dominant acreage positions in targeted areas, thereby leveraging proprietary knowledge and expertise in those plays."
Ongoing evaluation work, including appraisal drilling, is currently being conducted to determine the size of the hydrocarbon resource discovered in Block 2(c). An exploratory drilling program will also be conducted in Block 3(a) as part of the minimum work requirement of the Production Sharing Contract.
