Middle East Energy Shift: From Light Oil Decline to Heavy Oil Opportunity
Regional Focus:
For decades, the Middle East was defined by light oil production. But as many of those wells decline, operators are increasingly turning to heavy and extra-heavy oil reservoirs to maintain output. The opportunity is significant but unlocking it depends on using the right EOR approach.
The Regional Challenge:
Heavy oil behaves very differently to light oil. Its higher viscosity means mobility is reduced unless sufficient heat is applied. Traditionally, steam has been the default solution but it comes with major drawbacks.
Steam-based methods:
- Require desalination plants and extensive surface infrastructure
- Drive high operating and maintenance costs
- Accelerate corrosion across pipeline networks
- Increase environmental impact and emissions
Operators now need alternatives that manage oil mobility efficiently, economically, and sustainably.
Where THOR Fits:
THOR delivers targeted downhole heat directly at the reservoir, without the complexity of steam.
- Deployed via workover rig, similar to an ESP
- Precise temperature control to optimise heavy oil flow
- Remote monitoring allows operators to hit optimal conditions without being on site
- Eliminates waxy build-up and thick extraction challenges
- Reduces CO₂ emissions by up to 20x compared to steam
Proven Operator Impact:
For extra-heavy oil wells, THOR has shown:
- Faster production response than steam
- Significantly lower operating costs
- No requirement for surface infrastructure
Case Study Snapshot:
Pilot operations are underway in the Middle East with Wildcat United, represented by Dr Abed. A well producing 27 barrels of oil per day (bopd) on cold production increased to 71 bopd after heating forming the basis for a planned 150-well expansion.
Looking Ahead:
As Middle East operators transition from mature light oil fields to heavier reservoirs, traditional steam-based EOR was developed for a different era one where water availability, surface footprint, and emissions were secondary considerations. Today, those constraints are crucial where high water demand, corrosion-heavy infrastructure and long heat-up times, make steam increasingly difficult to justify at scale across the region.
THOR offers a different approach, by applying controlled heat directly at the reservoir, operators can mobilise heavy and extra-heavy oil without the surface complexity of steam. This is particularly well suited to the Middle East.
