May 21 (Bloomberg) -- Transocean Inc., which owns one- fourth of the global supply of deepwater oil rigs, drilled the world's longest well off the coast of Qatar, surpassing the old record by almost a half mile (805 meters).
The well extends for 40,320 feet, including a 35,770-foot horizontal section, the Houston-based company said today in a statement. Transocean's offshore GSF Rig 127, which has retractable legs that extend to the seafloor, drilled the well in 36 days as part of a $6 billion A.P. Moeller-Maersk Group project.
The well exceeded the previous record length of 38,322 feet set earlier this year at Sakhalin Island off Russia's Pacific Coast, Transocean said. Maersk Oil & Gas, a unit of Copenhagen- based A.P. Moeller, plans to boost output from Qatar's Al Shaheen field to 525,000 barrels a day by the end of next year.
Oil and gas producers including Exxon Mobil Corp. and Royal Dutch Shell Plc are using more horizontal wells to tap reserves formerly regarded as uneconomical.
