Expro Excellence
Fluids sampling and analysis
Expro expertise supports testing for UK’s first geothermal power plant
Customer challenges
  • The United Downs Deep Geothermal well project will deliver the UK’s first geothermal generated electricity, as well as district heating, and enable sustainable, low-impact lithium extraction
  • Geothermal Engineering Ltd (GEL) required Expro to capture representative samples of high temperature geothermal fluids and establish their composition
  • Detailed analysis was needed to:
  • Aid design of the geothermal power plant
  • Confirm the presence of lithium and suitability for extraction
  • Identify any risks to personnel or facilities from corrosion and scaling
  • Verify absence of hydrocarbons
Expro Excellence
  • Expro developed unique sampling procedures to meet requirements for the project, working with multiple stakeholders to identify key objectives
  • Our tailored approach safely delivered high temperature single phase wellhead sampling, ensuring samples remained valid up until time of analysis
  • Expro safely and efficiently delivered this high-profile, first of its kind project in the UK with zero NPT and 100% Job Performance
  • Despite very low Gas Water Ratio (GWR), Expro’s experience in handling pressurized fluids allowed us to obtain representative sub-samples and complete an extended suite of analysis of the water and the entrained gas
Value to client
  • Expro’s analysis enabled GEL to report the highest concentrations of lithium measured globally in geothermal fluids to date
  • Measurements indicate that zero-carbon, low impact production of battery grade lithium, a key component of the UK’s clean energy ambitions, will be possible
  • Extraction efficiencies of 95% are expected thanks to low concentrations of interfering ions, such as magnesium, found during Expro’s testing
  • Our analysis of the fluid composition informed the subsequent tender and design of the power plant, and plans for corrosion and scale monitoring
  • GEL expect to produce enough green electricity to power 45,000 houses, and district heating for local homes and businesses
