Oil and gas services provider Noble said Friday that Mark A. Jackson has resigned as chairman, president and chief executive, effective immediately, and will be replaced on an interim basis by William A. Sears.
Sears has been a director of the company since January 1998. Sears has more than 40 years of experience in the oil and gas industry and retired from his position as director of operations for British Petroleum Exploration in 1997.
The board has formed a search committee to review internal and external candidates to fill the president and CEO position on a permanent basis.
Noble performs contract drilling services with a fleet of 62 mobile offshore drilling units located in the U.S. Gulf of Mexico, Middle East, Mexico, the North Sea, Brazil, West Africa and India. The fleet count includes five rigs under construction.
