Occidental Petroleum is Making a High Upside Bet With ExxonMobil. Here's What it Could Mean for Investors.
Occidental Petroleum will acquire a 10% interest in ExxonMobil’s deepwater exploration block offshore Trinidad and Tobago (UD(1)), according to the article. Exxon previously held 100% and is conducting seismic surveys, planning $42 million for seismic and up to two wells. Exxon estimates up to $21.7 billion to develop if results match Stabroek’s 30 discoveries and 900,000 bpd output.

Stake purchase ties OXY to a higher-upside exploration area near Exxon’s prolific Stabroek play, but with meaningful dry-hole risk.
Occidental is buying a 10% stake in Exxon’s deepwater UD(1) block offshore Trinidad and Tobago, adding a potential long-term growth catalyst.
Mild-to-moderate positive bias for OXY as investors price optionality; volatility likely around exploration milestones.
Background
Occidental previously held a 100% stake in the Ultra Deep 1 (UD(1)) block; Exxon acquired it last year via a Trinidad and Tobago government deal and is now farming out 10% to OXY.
Why it matters
OXY gains exposure to a potentially prolific deepwater area adjacent to Exxon’s Stabroek block, while Exxon reduces exploration risk/capital needs by bringing in a partner.
Market relevance
This is a farm-down/partnering exploration transaction that should trade primarily as optionality for OXY and as risk/capital management for XOM.
Market effects
Reinforces the ongoing strategy of farm-down/partnering in deepwater exploration to manage capital intensity while targeting large resource upside.
Highlights continued investment interest in offshore Trinidad and Tobago deepwater acreage tied to Guyana/Stabroek read-through.
Signals sustained capital allocation toward large-scale offshore discoveries and cross-border portfolio diversification among major operators.
Alternative perspectives
Proximity to Stabroek doesn’t guarantee UD(1) success; the deal may be more about risk transfer than value creation if geology differs materially.
The article omits deal economics (price/terms) and timing of potential drilling approvals; market reaction may hinge on those details and on how investors view Exxon’s seismic results.
