The thesis
Why this org is unusual
The most distinctive feature of Occidental’s structure is the reinstatement of a formal COO role in late 2025 after several years without one.
Richard Jackson’s promotion created a clear operational aggregation point, consolidating U.S. onshore, offshore, midstream, and low‑carbon execution under a single executive. This reduces the CEO’s direct operational span while sharpening accountability for asset performance and integration.
The organization is otherwise classically divisional, with a strong split between U.S. operations, international operations, and technology. International oil and gas is run as a semi‑autonomous division under its own president, reflecting geopolitical and asset‑mix differences. Technology is centralized under a Chief Petrotechnical Officer rather than embedded in each division, signaling continued emphasis on reservoir optimization and subsurface differentiation across assets.
Corporate functions remain lean at the top. Finance, compliance, and governance report directly to the CEO, while HR and legal are embedded within compliance rather than elevated to separate C‑suite roles, keeping the executive team relatively compact for a global energy producer.
- COO role reinstated in 2025
- Centralized petrotechnical leadership
- Dedicated international president
The comparison
How Occidental Petroleum Corporation stacks up
Compared with U.S. integrated and independent peers, Occidental’s executive structure is slightly flatter but more centralized around operations. Unlike Chevron or Exxon Mobil, which embed technology leadership deeper within business units, Occidental elevates petrotechnical leadership to the CEO’s table. This mirrors …
