Thistle Creek Capital

J. Mike Stice is the Managing Partner and leads investment decisions. His background is operational, not financial — he was President of ConocoPhillips Qatar, CEO of Chesapeake Midstream Partners, and Dean of the Mewbourne College of Earth and Energy at the University of Oklahoma. Investment decisions at Thistle Creek reflect this hands-on energy-operator lens.

The wealth originates from the energy sector. Stice's executive career at ConocoPhillips and his leadership of Chesapeake Midstream Partners — one of the largest midstream MLPs formed during the shale revolution — are the likely primary sources of the capital Thistle Creek deploys.

There is no public evidence that Thistle Creek engages in upstream exploration and production. The firm's known investment themes — midstream infrastructure, carbon capture, hydrogen, and CO₂ transportation — position it in the infrastructure and energy-transition layers that sit between the wellhead and the end user.

Thistle Creek operates as a single-family office. It does not market to external LPs and does not publicly disclose a fund structure. This privacy is consistent with an operator-principal deploying personal capital directly into areas of deep domain expertise.

Stice has been publicly vocal that the energy transition must work with, not against, existing hydrocarbon infrastructure. Thistle Creek's investments appear to target the decarbonization stack — carbon capture, utilization, and storage (CCUS); hydrogen from natural gas; and midstream assets that can be repurposed for low-carbon fuels. The thesis is pragmatic: the people who built the energy system are best positioned to decarbonize it.

Public filings and available records suggest a preference for direct investments and board-level engagement rather than passive fund commitments. Stice's board service at portfolio-adjacent companies aligns with a direct, operationally involved investment style.

No publicly disclosed affiliated investment firm, foundation, or co-investment vehicle has been identified. The firm appears to operate independently as the Stice family's investment office without shared branding or pooled structures.
