Mark Agnew, originally from Australia, has built a rewarding career in the oil and gas industry. After spending his early years in Singapore and Australia, he moved to Houston, Texas, during high school, following his father’s career in oil and gas. He earned a Bachelor of Science in Petroleum Engineering from The University of Texas at Austin, graduating with high honors in December 1989.

He then joined Exxon in New Orleans, where from 1991 to 2000 he held various roles in reservoir, drilling, completions and commercial operations, eventually becoming a reservoir engineering supervisor focused on South Louisiana and offshore fields. In 2000, Mark moved to Jakarta, Indonesia, as reservoir and subsurface engineering manager for EM Indonesia, leading teams managing the Arun gas field. In 2003 he relocated to Houston where he served as regional coordinator for Canada and South America. In 2005 he became production operations superintendent at Mobile Bay in Alabama, followed by a role as U.S. equity crude sales manager in Fairfax, Virginia (2005–2007), managing a team of crude oil traders.
