Technology
Turning extreme heat into dependable power
Superhot geothermal is not a one-component problem. The well, reservoir, surface systems and operating methods must work as one.
01 One integrated system
Everything connects
Materials determine the completion. The completion determines the operating envelope. The operating envelope shapes the surface system and the power plant. Each interface must work as part of one system under extreme temperature, pressure and fluid conditions.
Eldar owns and integrates that architecture. Specialist partners manufacture components and contribute expertise within a common system design.
02 The Eldar platform
What Eldar is building
Well design and integrity
Materials, casing, cement, connections and wellhead systems designed to survive thermal cycling and sustained superhot operation.
Reservoir engineering
Well placement, stimulation and operating strategies that access commercial flow while managing the reservoir over time.
Surface systems and power
Fluid handling, pressure control, separation and power-generation systems designed around the defined operating envelope.
Operating intelligence
Monitoring, modelling and operational data that improve well performance, field development and each subsequent project.
03 The challenge
What gets harder at temperature
Every part of a conventional well design carries an assumption that superhot conditions break.
Drilling
High temperature narrows the working window for bits, bottom-hole assemblies, drilling fluids and logging tools, and raises the cost of every hour of non-productive time.
Well construction and integrity
Casing, cement and connections have to absorb large thermal expansion and hold zonal isolation through heat-up and years of production.
Materials
Aggressive chemistry at temperature attacks conventional grades. Where corrosion-resistant alloy is genuinely needed, and where standard casing will hold, drives both well integrity and cost.
Surface systems
Pressure control, flow assurance, silica scaling and erosion all get harder, and the package protecting the power block has to be specified for the fluid it will actually see.
04 Industrialisation
From first-of-a-kind to repeatable delivery
A standard core architecture, defined field interfaces, qualified components and a growing body of operating data turn one-off engineering into a system for deployment across fields.
Each project shortens delivery, reduces risk and improves the economics of the next.
05 Field validation
Proving the system in the ground
The Icelandic pilot will validate construction, completion, heat-up, controlled flow and monitoring in the target environment.
More than a test of one well, the pilot will create the commercial design basis, supplier package, operating envelope and field evidence for the first commercial module.
