"If I ever get in trouble, he's the first man I'll call. He runs a tight ship and plays the game with both feet on the ground. He did a phenomenal job." Jack O'Neill has been trying large complex cases for over 45 years. His experience in the courtroom involves many cases that have been widely publicized. Mr. O'Neill was co-trial counsel for UPR, Inc. in its attempted takeover of Pennzoil. He was lead counsel for Mitchell Energy Corporation in the company's effort to overturn a $204 million judgment rendered against the company in a case tried for the company by another law firm. On appeal, argued by Mr. O'Neill, the case was reversed in its entirety and judgment was rendered in favor of Mitchell. He was lead trial counsel for Mitchell Energy in a related case in which plaintiffs sought $750 million for alleged contamination of their properties by natural gas and hydrogen sulfide. After a three-month trial, the jury rendered a unanimous verdict in favor of Mitchell. He was lead trial counsel for plaintiffs in the highly publicized Key 1-11 gas well blowout case in the Texas Panhandle, the largest blowout of a gas well in continental United States history. After a trial lasting over two and a half months, the jury returned one of the largest verdicts in Randall County, Texas history in favor of Mr. O'Neill's clients. He was lead trial counsel for a well-known Houston oil and gas company in a fraud case in which the plaintiff sought damages in excess of $100 million. After a two-month trial, the jury returned a verdict for Mr. O'Neill's client, and a take-nothing judgment was entered by the trial court. Mr. O'Neill has successfully tried many other cases relating to virtually all aspects of the oil and gas industry. Mr. O'Neill is a former director of the Litigation Section of the State Bar of Texas. He also is a member of the American Board of Trial Advocates.
