Anthony Petrello is known first for his contributions to the oil industry. He’s the Chairman and CEO of Nabors Industries, a major oil drilling contractor company based in Houston, TX. As CEO, Petrello is responsible for new technological developments and planning the overall direction of the company. Over the years from Petrello’s time as Chief Operating Officer up till now, Nabors has assembled the world’s largest land and offshore rig fleets and has developed many patents in drilling science and automated technology. They are also a large publicly-traded company on the NYSE and Petrello is also responsible for attracting more investors to the company.
His gift for solving math problems earned him acceptance into Yale University where he studied under Serge Lang, one of the world’s most renowned mathematicians. Petrello originally considered becoming a professor in the field himself, but he soon found an interest in corporate law and enrolled in Harvard’s law school where he got his J.D.
Petrello joined Baker & McKenzie, a New York law firm in 1979 where he advised clients in all the legal aspects of big transactions such as mergers and acquisitions, business valuations, underwriting, employment and tax compliance issues. He became very proficient in financial law that in 1986 he became a Managing Partner at the firm. He also became sought after by clients who wanted him to join their executive leadership team, including Eugene Isenberg of Nabors Industries who was very pleased with Petrello’s work. So in 1991 Petrello joined Nabors as its Chief Operating Officer.
Petrello has also given millions to research in neurological disorders at the Texas Children’s Hospital. He and his wife Cynthia’s daughter Carena was born with a condition that was diagnosed as Cerebral Palsy, and as a result she has been confined most of the time to a wheelchair and has difficulties with basic functions. Petrello was told there was nothing that could be done to treat his daughter, but he didn’t give up hope that one day a cure might be found. So he joined TCH’s Board of Trustees and made a generous contribution of $7 million to the Dan and Jan Duncan Neurological Research Institute.
