Total Fina Elf: Further Gas Reserves Discovered in Bolivia’s Block Tarija XX West
TotalFinaElf announces the discovery of further gas reserves in southern Bolivia’s Block XX Tarija West. The interest holders in the block are TotalFinaElf (41%, operator), ExxonMobil (34%) and BG Bolivia (25%).
The recently completed Itau X-2 delineation well penetrated the Upper, Middle and Lower Devonian formations, including the deep Santa Rosa Formation, which had not been tapped by the Itau X-1 discovery well.
During testing, the Huamampampa reservoir interval flowed at 0.8 million cubic meters per day of gas and 600 barrels per day of condensate on a 40/64-inch choke. The Santa Rosa formation tested at 1 million cubic meters per day of gas and 350 barrels per day of condensate on a 48/64-inch choke.
Located five kilometers south of 1999 discovery well Itau X-1, the Itau X-2 well expands the gas potential of Block XX Tarija West.
TotalFinaElf also has a 15% interest in the neighboring San Alberto and San Antonio blocks, whose gas resources are under development. Phase 1 production of 6.6 million cubic meters per day of gas for the Brazilian market began on San Alberto in early January 2001.
