Occidental Petroleum's Federal Lobbying Record

Occidental Petroleum's $5.9M in disclosed federal lobbying puts it in the mid-tier of registered filers. Spending in the seven-figure range is common for established trade groups, mid-size corporations, and advocacy organizations that maintain a steady but not aggressive presence on Capitol Hill.

Across the 5-year window from 2020 to 2024, Occidental Petroleum's annual disclosed lobbying spend has climbed modestly — from $1.0M in 2020 to $1.1M in 2024, a change of +10%. Step-changes of this size often coincide with major bills moving through Congress, regulatory rulemakings affecting the organization's industry, or a leadership change in the relevant committee.

Occidental Petroleum's disclosed lobbying covers 5 general issue areas — a moderate footprint. Filers in this range tend to engage on a coherent cluster of related topics rather than spreading effort across the federal agenda.

2 of 4 lobbyists reported by Occidental Petroleum (50%) disclose prior federal government service — a high revolving-door share. The LDA cover sheet flags any "covered position" the lobbyist held in the executive branch, Congress, or a senior staff role within the past two years.

Among the named bench, lobbyists with disclosed prior federal service include Nancy P. Carter (Former Staff Director, Senate Banking Committee); Steven J. Elmendorf (Former Deputy Director, OMB). The covered-position field on LDA cover sheets captures executive-branch and senior congressional roles held within the prior two years.

Within the Energy & Natural Resources sector, Occidental Petroleum ranks #21 of 35 tracked organizations by disclosed lobbying spend. The sector leader is ExxonMobil at $46.5M; the sector average is $11.8M. Occidental Petroleum's $5.9M sits 50% below the sector average.

Occidental Petroleum's LobbySpend Influence Score of 62/100 (grade B) reflects significant federal lobbying reach. The score blends disclosed total spend, issue breadth, and revolving-door connections — lobbyists with prior federal government service. A B-grade typically means the organization is well above average on at least two of those three signals, with sustained activity over multiple years rather than a one-off spike.

Every figure above is sourced from Senate lobbying disclosure filings submitted under the Lobbying Disclosure Act of 1995. Per-issue dollar splits and covered-position flags are filer-reported and may be amended after initial submission.
