Nabors
Nabors, the world's largest land-drilling contractor, pivots into an energy-transition platform under CEO Anthony Petrello.
Nabors
Nabors operates as a publicly traded entity, not a traditional investment firm, yet its capital allocation increasingly mirrors that of an asset manager directing billions into heavy industrial technology. Founded as Anglo Energy in 1968 and reincorporated in Bermuda, the company evolved through decades of consolidation to become the dominant global land-driller. Chairman and CEO Anthony Petrello, who previously served as Nabors' chief operating officer, has presided over this transformation alongside CFO William Restrepo. The wealth-generation engine is not a liquidated operating business but the ongoing cash flows of a fleet exceeding 300 rigs worldwide. The deployment strategy spans traditional hydrocarbon drilling, but the firm's distinct edge lies in its aggressive push into energy-transition infrastructure. Nabors committed over $100 million to advanced geothermal ventures through its subsidiary Nabors Energy Transition Corp., including an investment in GA Drilling (per Reuters, 2023). It holds a majority stake in Vast Solar, an Australian concentrated solar thermal power developer, and has pioneered fully automated rig systems through its Canrig robotics division. Geographic reach concentrates on North America, the Middle East, and Latin America. Capital is directed both organically, into proprietary rig automation and emissions-reduction technology, and through corporate venture-style equity positions in startups adjacent to its core operations. Nabors employs roughly 12,000 people globally. In May 2024, the firm expanded its energy-transition portfolio by launching Nabors Energy Transition Solutions, a dedicated arm for commercializing geothermal and emissions-capture technologies (per the firm's press release, May 2024). The company's subsidiary, Nabors Energy Transition Corp. II, a special purpose acquisition vehicle, actively sought targets in the renewables and decarbonization space. Philanthropically, the Petrello family has directed substantial personal giving to neurological research and children's hospitals, though this operates separately from the corporate entity. The firm's club-like co-investment model is absent — Nabors acts as a corporate strategic buyer, not a family-office allocator pooling capital from peers. The genuine structural differentiator is Nabors' operator-investor hybrid posture. It does not simply allocate capital to funds; it deploys its own balance sheet and operating expertise to take controlling stakes in technologies it then commercializes across its extensive customer network. This generates a return path distinct from financial engineering — monetizing technology through accelerated adoption at drilling sites in 20 countries. Succession risk is managed through board continuity, with Petrello having been in an executive leadership role since 1991, embedding the strategic direction deeply within the corporate governance.

Frequently asked questions
How does Nabors invest in the energy transition?
Nabors invests directly from its balance sheet and through its dedicated SPAC arm, Nabors Energy Transition Corp. II, targeting geothermal, emissions monitoring, and concentrated solar power. It takes controlling or significant minority stakes — such as its majority ownership of Vast Solar — and integrates new technologies into its global drilling operations to accelerate commercialization.
Who is Anthony Petrello and how long has he led Nabors?
Anthony G. Petrello has served as Chairman, President, and CEO of Nabors Industries since 2011, and previously held the role of Chief Operating Officer since 1991. He is one of the longest-tenured executives in the oilfield services sector and the primary architect of Nabors' diversification into technology and energy transition (per the firm's official communications).
Is Nabors a family office?
No. Nabors is a publicly traded, Bermuda-domiciled corporation listed on the New York Stock Exchange. It operates as an energy services and technology company, not a single-family or multi-family office. Its investment activity is corporate venture and strategic M&A, not third-party wealth management.
What is Nabors' approach to automation and technology?
Nabors invests heavily in automating its own fleet through its Canrig robotics and software division. It develops proprietary rig control systems and has deployed the world's first fully automated land rigs. The firm commercializes this technology across its global fleet and, in some cases, licenses it to third-party operators.
Which sectors does Nabors explicitly avoid?
Nabors does not invest in sectors unrelated to its core industrial and energy-transition mandate, such as consumer software, financial services, or biotechnology. Its corporate venture activity remains tightly focused on technologies that can be integrated into wellsite operations or provide adjacent decarbonization pathways.
