Who is responsible?

Gareth is an entrepreneur and the founder and long-time leader of a large public oil and gas company. Born in the UK, he studied geology at Oxford University before working for Texaco and Murphy Oil in the US and UK. In the 1980s he became independent and founded Denbury Resources, which grew into a $10 billion company under his leadership. He stepped down from Denbury and has since been involved in creating businesses in carbon sequestration and helium exploration.

Gareth has been involved with businesses in Canada since 1980, when his first company was funded on the Vancouver Stock Exchange; he led a successful US exploration effort for Calgary-based Coho Resources, and Denbury itself became a Toronto Stock Exchange-listed Canadian company in 1992 through a reverse merger with Canadian Newscope before listing on the NYSE.

After the 2008 financial crisis he left Denbury and, through 2CO Ltd, engineered a complete carbon-capture project at a UK coal plant with North Sea storage; the UK government elected not to fund the project through completion. That experience in CO₂ capture and storage, and in oxy-fuel combustion, led to the formation of Valverde. He holds Honours and Master’s degrees in Geology from St Edmund Hall, Oxford, where he is an Honorary Fellow and a member of the Chancellor’s Court of Benefactors. He is a trustee of the Horsfall Trust in Bradford and chairman and owner of Bradford (Park Avenue) AFC.

David began his career at Mobil Oil’s accounting centre in Dallas, worked as a corporate auditor at Mobil’s Joliet refinery, and completed a twenty-year career with ExxonMobil as an accounting team leader. He then spent nineteen years with Denbury Resources. He is a graduate of Columbia Business School’s CFO Executive programme and holds a BBA in Accounting from UT-RGV. He has served on the board of the Ford Performance Club of North Texas and as Vice President of the Frisco Velodrome.

David most recently served as Managing Director and Head of the Upstream E&P Group at Capstone Partners, leading equity and debt capital formation and strategic advisory mandates, including CO₂-flood asset acquisitions. He co-founded Sierra Partners LLC (2008–2015), advising domestic and international energy clients on M&A, acquisitions and divestitures and private-equity raises, and served as investor-relations consultant to Kodiak Oil & Gas. Earlier he spent nine years with a Denver oil and gas investor-relations consultancy, working closely with Gareth Roberts during his tenure at Denbury. He holds a BSc in Business Administration from the University of San Francisco and an MA in Journalism from the University of Iowa.

Randy developed and executed marketing strategies for Sun E&P, Oryx Energy, Kerr-McGee and Merit Energy, negotiating and structuring agreements across gas gathering, compression, dehydration, treating, transportation, processing, NGL fractionation, storage and exchange. He led financial and accounting teams supporting CO₂ asset operations at Denbury, developing usage-rate models for compression, dehydration, transportation and recycling facilities, and was a key contributor to Oryx’s PREMAS (SAP/PRA) marketing and accounting system. He holds a BSc in Accounting and Controllership from North Texas State University.

Dave has led innovation and market expansion for Mobil Oil, Valero Energy, TXU and Tri-State G&T. He combines commercial execution with technical fluency in thermal generation, specifically oxy-fuel technologies, and structures agreements around key performance metrics such as availability guarantees, ramp rates and heat rates. He holds a bachelor’s degree in business from Stephen F. Austin State University.
