Geothermal – Repurposing Oil/Gas Wells

Stellae Energy is working to identify end of life oil or gas wells to be repurposed for the generation of clean, dispatchable Geothermal Energy. The Energy Transition includes reusing existing infrastructure as part of a Circular Economy and then to use more Renewable Energy. With hundreds of thousands of potential wells available to be evaluated, this is an important opportunity to extract more value from existing resources in an environmentally sustainable manner.

Please get in touch at us@stellaeenergy.com if you wish to know more or interested in collaborating with us.
For those of you who are already working with us on this exciting opportunity, thank you so much for your continuous support.

Gulf of Mexico

  • Tens of thousands of end of life oil and gas wells are waiting to be abandoned;
  • Environmentally sustainable value is possible from some of these wells, allowing abandonment to be postponed;
  • Good well data of many wells with Bottom Hole Temperatures >212degF (100degC) and a significant number >302degF (150degC) – potentially suitable for low enthalpy power generation using economically developable sedimentary reservoirs;
  • Good existing infrastructure with wells, platforms, and pipelines able to host Geothermal energy production and power export systems including potential Green Hydrogen mixed into existing gas export pipelines.

Offshore UK North Sea

  • Thousands of inactive and/or end of life oil and gas wells are waiting to be abandoned in the North Sea;
  • Environmentally sustainable value may be possible from some of these wells, allowing abandonment to be postponed;
  • In 2018, water production accounted for 90-95% of total fluids production in mature fields of the North Sea.  Some fields producing 10-15,000 BOPD produce over 300,000 BWPD.  Circulating water through geothermally heated reservoirs is a key mechanism of Multiple Well Open Systems, so some of these reservoirs may be suitable for this kind of Geothermal energy solution;
  • More than 50 no. facilities have elevated well bottom hole temperatures suitable for low enthalpy power generation solutions, illustrating the concept of good geothermal heat gradients associated with some hydrocarbon accumulations
