Geothermal Services

Enhancing project efficiency, effectiveness, and profitability

The formula for success in geothermal project is an informed, interdisciplinary approach that brings together innovative science and engineering, practical experience, and hands-on project management.

The acquisition of GeothermEx in 2010 places Schlumberger in a unique position to serve the geothermal industry. Our work in hundreds of geothermal fields in more than 50 countries means that no company is better equipped for geothermal success than Schlumberger, which has been working in the subsurface since 1922.

We cover the full spectrum of geothermal operations—from exploration to drilling and testing to project management, resource monitoring, and operational support.

Enhanced Geothermal Systems (EGS)

Reservoirs with subcommercial permeability can be made economically viable with hydraulic stimulation techniques. Schlumberger’s extensive experience with tight shale projects has resulted in expertise and technologies that are directly applicable to EGS developments.

Our unique experience in the domain is leveraged to improve the effectiveness of fracture network enhancement and heat exchange in EGS reservoirs.

Our approach to EGS

  • Wellbore image logging, processing, and interpretation
  • Geomechanics and stress field analysis
  • Core testing for mechanical and petrophysical properties
  • Design and implementation of multizone EGS well completions
  • Stimulation planning, implementation, and monitoring
Reservoir-wellbore-pipeline simulation in Geysers Field, California
We developed an integrated model for the Northern California Power Agency that combines reservoir simulation with mathematical modeling of the wellbores, pipelines, and power plants, making it easier to quantify the impact of operational augmentations.

Independent, accurate analysis

Every geothermal project has uncertainties, particularly at the early stages of development. Even during later stages, the most significant variable in any geothermal project is the resource itself. Assessing resource risks and opportunities is crucial to long-term success.

When government agencies and financial institutions need independent third-party assessments of the capacity, sustainability, and value of geothermal resources, many come to us for

  • national and regional evaluations of geothermal power potential
  • technical support for policies and financial incentives to enable more geothermal power
  • identification and mitigation of geothermal resource risks
  • in-depth resource analyses and numerical simulations of geothermal reservoir performance
  • financial modeling and project valuations.
