Gulf of Thailand drilling/completion both high tech and high volume, with HSE as core value

By Mike Killalea, Editor & Publisher Drilling in the Gulf of Thailand (GOT) is not only high-volume work, but presents considerable technical drilling-and-completion challenges. Chevron, the major operator in the GOT, drills some 40% of its global footage there – that’s right, 40%. In 2007, that constituted 3.7 million ft and 310 wells, and the previous year, 4.4 million ft. Chevron’s preeminence in the region more than doubled following the 2005 merger with Unocal.

Permanent magnet motors lead way to better power efficiency, safety on cranes, winches

By Hege Kverneland, National Oilwell Varco Recognized around the world as a leader in technology-driven drilling solutions, National Oilwell Varco (NOV) has kept its focus on commercializing permanent magnet motor technology and developing innovative applications for its use. The Lifting and Handling Group’s latest technological development is the new all-electric King Post Crane using permanent magnet motor (PM motor) technology with a new type of permanent magnet motor winch (PMW). PM motor Technology The technology of the PM motor differs from the traditional squirrel cage AC asynchronous motor in that it uses permanent magnets to generate the magnetic flux to turn the motor, versus excitation by copper or energizing large copper winding in the rotor. The benefits of the PM ...

Lifting Safety: Inexperienced employees, deepwater/subsea projects push lifting challenges to new

“The challenges have shifted,” said Mike Brasic, who retired from BP in May 2008 as lifting adviser and as HSE manager for BP Sakhalin. First, there’s the people problem. “The level of experience among employees has gone down as the level of activity has gone up. That’s presenting challenges with competency that the industry must address.” Second, the move into deepwater and subsea operations has brought its own set of technological and safety challenges – including lifting challenges. “It’s a new phase to the lifting game,” he said. Lifting performance Mr Brasic believes the industry has seen a decrease in lifting fatalities and serious incidents in recent years, and several factors have contributed to that. “There’s more focus on near-miss ...
