Deep Slimhole Gradient Drilling

Unlocking the Earth’s Heat with Precision and Efficiency

 At London Geothermal Ltd, we offer specialized deep slimhole drilling services as a strategic and cost-effective approach to geothermal exploration. Slimhole wells—typically ranging from 300 meters to 2,500 meters—enable our clients to validate reservoir temperatures, rock properties, and pressure profiles at depth with minimal environmental and financial footprint. 


Why Slimhole?

Integrated With Our Full-Service Geothermal Model

Our Capabilities

  •  Lower CAPEX compared to full-diameter wells
  • Ideal for pre-feasibility and bankable feasibility studies
  • Enables thermal gradient mapping and reservoir calibration
  • Reduced drilling fluids, pad size, and land disturbance
  • Serves as future monitoring or reinjection wells

Our Capabilities

Integrated With Our Full-Service Geothermal Model

Our Capabilities

  • Vertical and deviated drilling up to 2,500 meters
  • High-temperature downhole logging and core sampling
  • Integration with fiber optic and borehole heat exchange monitoring
  • Full permitting, logistics, and casing design
  • Ability to mobilize in both urban and remote environments
