Occidental Petroleum is a publicly traded company in the Energy sector. This company operates across Energy and is subject to various Congressional legislative and regulatory actions. HillSignal is tracking 11 active Congressional signals mentioning Occidental Petroleum, including 11 bills. The legislative sentiment is currently mixed, with both supportive and challenging policy signals in play.
HR8108 targets two specific tax credits that support enhanced oil recovery — the Section 43 EOR credit and the Section 45Q credit for CO2 used as tertiary injectant. This directly threatens Occidental's EOR business model and has secondary implications for Devon's mature field operations. However, the bill is at early-stage committee with 11 cosponsors and minimal legislative momentum, so near-term passage risk is low. Occidental's stock has recovered 5.74% over the past 7 days to $60.40 despite the 30-day decline of 7.08%, suggesting the market is not pricing in this legislative risk.
→ New CO2-EOR projects after enactment lose the 45Q carbon capture credit for injection use and the 43 EOR credit entirely, raising the after-tax cost of new EOR wells by an estimated 10-20% based on typical project IRRs that depend on these credits for acceptable returns.
HR8034 targets a structural tax benefit for domestic oil and gas producers by reducing percentage depletion deductions on marginal wells. This is an early-stage House bill with no near-term passage risk, but its introduction is a signal of legislative focus on energy sector tax preferences. $EOG and $OXY face the highest relative earnings risk given their pure-play domestic E&P exposure.
→ Reduces the allowable depletion deduction by up to 10 percentage points for marginal wells, increasing taxable income.
HR1555 eliminates federal drilling permits and NEPA reviews for oil/gas wells on non-federal surface where the U.S. owns less than 50% of the subsurface minerals. This directly benefits the four major Permian Basin operators—ExxonMobil, Chevron, EOG Resources, and Occidental Petroleum—by cutting 30-90 days of regulatory delay per well and lowering compliance costs. The bill is currently in subcommittee markup in the 119th Congress, with active legislative momentum and bipartisan executive support through the recent DPA energy memoranda.
→ Removal of federal permitting requirements for a large portion of OXY's operated wells; state permits become the sole required approval
HR 7960 (Big Oil Windfall Profits Tax Act) is an early-stage bill referred to committee with low passage probability. It introduces headline risk to the energy sector but has no near-term financial impact. Real market data shows a broad 7-day rally across the sector (XOM +3.79%, CVX +4.1%, MPC +8.82%) despite a mixed 30-day trend, indicating that investors are not pricing in this legislative risk.
→ If Brent crude oil average price in a calendar quarter exceeds the 2025 annual average (plus inflation adjustment), the excess multiplied by 50% becomes a per-barrel tax liability on each barrel extracted and removed
HR7831 extends BLM drilling permit fees through 2037 with minimal near-term market impact. Occidental ($OXY) is the most exposed large-cap at <$10M/year in added costs. The bill is in early committee markup with low momentum. Current oil sector price moves (+3-5% over the last 7 days) are driven by macro oil supply factors, not this procedural fee extension.
→ Operators face a small, persistent per-APD fee through 2037 instead of expiration in 2026, increasing the marginal cost of federal drilling permits by the fee amount annually. For Occidental, which holds ~1.4 million net acres of federal land in the Permian Basin and Rockies, the fee represents a modest ongoing operational cost but does not alter drilling economics materially.
HR7882 would open federal mineral acreage inside Carlsbad, New Mexico city limits for leasing, expanding drillable inventory in the core of the Permian Basin. The bill is in early House committee stage with subcommittee hearings completed. Major Permian operators OXY, EOG, XOM, and CVX are structural beneficiaries of increased federal lease availability in the Delaware Basin. Real market data shows all four tickers up 3.8-5.0% over the past 7 days, recovering from 30-day declines of 3.5-8.9%.
→ opens previously unavailable federal mineral acreage in the Permian Basin's highest-productivity sub-play (Delaware Basin near Carlsbad) for competitive leasing, expanding drillable inventory
The Big Oil Windfall Profits Tax Act (S4111) imposes a 50% excise tax on crude oil profits above a 2025 baseline, directly targeting U.S. producers (XOM, CVX, EOG, OXY) and refiners/importers (MPC, PSX, VLO). The bill is in early committee stage with 12 Democratic cosponsors and a companion in the House, indicating partisan momentum but a long legislative path. Despite recent 7-day rallies in oil stocks (XOM +3.7%, MPC +8.74%), the bill signals a clear policy risk to upstream margins and refining costs.
→ Reduces upstream profit margins by 50% on any barrel sold above the baseline average Brent price from calendar year 2025.
The Carbon Resource Innovation Act (S.3778) is a procedural early-stage bill with zero near-term market impact. Energy stocks including OXY are in a verified 30-day downtrend (OXY -8.29%) completely unrelated to this bill. No price movement, no funding, no regulatory change is attributable to this legislation.
→ Ongoing early-stage legislative process with no committee markup, no fiscal estimate from CBO, and zero near-term changes to existing 45Q credit implementation or IRS guidance. No company currently generates taxable income from solid/liquid capture under this expanded definition.
HR2570 (Maximum Pressure Act) is an early-stage House bill at the referral-to-committee stage with zero funding, zero regulatory changes in effect, and a long, uncertain legislative path. No immediate market impact. Oil companies ($XOM, $OXY) may see marginal bullish support from potential future supply tightening, but the bill has not moved since introduction 13 months ago.
→ Same supply reduction effect. OXY's large domestic production (1.2 million boe/d in Permian) benefits from higher global oil prices without direct Middle East political risk from the bill.
S.2427 is an early-stage Senate bill that would force federal energy and mining agencies to regularly sunset and rejustify regulations, imposing zero direct spending. Combined with the recent executive branch alignment via DPA determinations on April 20, 2026, the legislative-executive push is structurally bullish for upstream operators with significant federal acreage exposure. Real market data shows XOM, CVX, DVN, and OXY all posting strong 7-day gains of +3.22% to +5.47% as this regulatory relief narrative gains traction.
→ reduction in regulatory compliance costs and permitting delays for oil and gas operators on federal lands and for carbon sequestration projects on federal acreage
S. 109 mandates 20 Gulf of Mexico lease sales over 10 years, locking in a predictable offshore drilling schedule. The bill is in early legislative stages, reducing near-term probability, but its passage would structurally benefit pure-play Gulf operators like Occidental, Chevron, and ExxonMobil by removing regulatory uncertainty. Market data shows a broad 7-day energy sector bounce with OXY leading at +5.07%, but the 30-day trend remains deeply negative (-8.27% for OXY, -9.8% for XOM) indicating the sector is pricing in headwinds beyond this bill.
→ Predictable, multi-year supply of new offshore drilling acreage in the Gulf of Mexico reduces regulatory uncertainty for operators, allowing longer-term capital planning and investment in drilling rigs, platforms, and subsea infrastructure.
