Timothy L. Dove, president and chief operating officer of Pioneer Natural Resources Co., Dallas, has been named president and chief executive officer of the company to succeed Scott D. Sheffield, who will retire at yearend.
Both executives worked for predecessor company Parker & Parsley Petroleum Co., which became PNR after the merger of Mesa Petroleum in 1997.
At the time of the merger, Sheffield was Parker & Parsley’s chairman of the board and chief executive officer and became chief executive of the new firm. He was elected chairman in 1999.
Dove was Parker & Parsley senior vice-president at the time of the Mesa merger and held several PNR executive positions before becoming president and chief operating officer in 2004.
Sheffield will continue as executive chairman of the PNR board through 2017, when he’ll retire as an executive and employee of the company but remain on the board.
