Halliburton (NYSE: HAL) appointed Timothy A. Leach to its board of directors effective 2 December 2025. The halliburton board appointment adds one of the Permian Basin’s most consequential operators — Leach founded Concho Resources in 2006 and built it to a $9.7 billion acquisition by ConocoPhillips in 2021.
Leach stood for shareholder election at the 2026 Annual Meeting. Halliburton Chairman, President and CEO Jeff Miller described his upstream operations expertise as “invaluable” to the company’s value proposition.
Tim Leach: Background and Permian Credentials
Leach spent 40 years in the Permian Basin before this halliburton board appointment. At Concho Resources, he served as Chairman and CEO from founding through to the ConocoPhillips merger — one of the largest shale consolidation transactions of the 2020s. After the deal closed, he served as Executive Vice President of Lower 48 at ConocoPhillips until retiring in August 2025.
A petroleum engineer by training, Leach holds an MBA from the University of Texas of the Permian Basin. He is a recipient of the TXOGA Distinguished Service Award and an inductee of the Petroleum Museum Hall of Fame — two of the upstream sector’s more substantive recognition markers in the Southwest.
What the Halliburton Board Appointment Signals
Halliburton generates the bulk of its North American revenue from hydraulic fracturing and completion services in the Permian Basin. Leach’s appointment deepens the company’s ties to the operator community it serves — he brings direct knowledge of how major E&P companies evaluate oilfield services spend, contractor selection, and technology adoption at scale.
His involvement with the Permian Strategic Partnership, a coalition of Permian Basin operators and community stakeholders, also gives Halliburton a board-level connection to one of the region’s most influential industry coordination bodies.
The appointment comes as Halliburton continues to invest in autonomous completions technology and digital oilfield services. An operator who built a Permian pure-play from startup to $9.7 billion brings a client-side perspective that is difficult to replicate from within a services organisation.

Permian Basin and Shale Consolidation Context
The Concho Resources deal — valued at $9.7 billion when ConocoPhillips closed it in January 2021 — was one of the defining transactions of the post-pandemic shale consolidation cycle. Leach navigated Concho through the 2014-16 downturn, the 2020 price collapse, and ultimately positioned it for the premium exit. That track record is directly relevant to the fracking sector’s ongoing consolidation dynamic that Halliburton’s completion services business operates within.
