Key Claims
- Iraq requires minimum 9 months to return to pre-conflict production capacity following Hormuz reopening, due to reservoir management constraints and resource limitations
- Reservoir damage from hasty shut-ins may be permanent for some wells — rapid restart risks "doing more long-term damage to foundational assets"
- Storage buffers are critically thin: Saudi Arabia and UAE have ~1 month of storage; Iraq and Kuwait have less than 2 weeks
- Even with "unconditional" Hormuz reopening, initial export volumes would remain below pre-conflict levels for at least 2 months before steady-state recovery
Context
Wood Mackenzie's upstream analysis, delivered by Head of Upstream Analysis Fraser McKay, addresses the question most observers are asking: what happens after the shooting stops? The answer is sobering — the Strait of Hormuz can reopen, but the oil cannot simply turn back on.
Reservoir Engineering Constraints
The core finding: Iraq's production recovery timeline is governed by reservoir physics, not politics. When wells are shut in rapidly (as happened in February-March 2026), reservoir pressure depletes and water or gas intrusion can permanently damage formation productivity. Some wells will need new interventions and drilling to restore flow.
The longer the shutdown persists, the worse the damage accumulates.
Storage as a Buffer
Saudi Arabia and UAE — the two countries with remaining spare capacity — have approximately one month of export storage buffer. Iraq and Kuwait have less than two weeks. This means the moment Hormuz reopens, Gulf producers face an immediate logistics bottleneck: their own storage is full, their customers' storage is depleted, and global tanker logistics are in disarray.
Operational Risk Warning
WoodMac's McKay specifically warned against operators being rushed by regulators and governments to restore production too rapidly. The warning is direct: "Operators hastened by regulators and governments to restore production too rapidly will risk doing more long-term damage to foundational assets."
This is a supply-side risk that most forecasts underestimate — they assume reopening = recovery, when in practice reopening = the beginning of a slow, complicated restart process.
Industry Confirmation
SLB CEO Olivier Le Peuch and Halliburton CEO Jeff Miller both confirmed on Q1 2026 earnings calls that the restart of Gulf wells would be a multi-month challenge, with the situation becoming "more complex the longer things are shut in."
Relevance to Q1/Q2
Directly supports Q1 Supply Destruction — quantifies the permanent supply loss component (not all shut-in production is recoverable). Also relevant to Q2 Price Impact — even with a ceasefire, price relief from supply restoration will be delayed by months, supporting the $100+ floor scenario.
