Webinar: Steam Enhanced Extraction – The tricky thermal solution for permeable sites

In case you missed our last installment of “Inside In Situ Thermal Remediation”, TerraTherm’s informational webinar series, you can find a recorded version here:

“Steam Enhanced Extraction – The tricky thermal solution for permeable sites”

Presented by TerraTherm’s Senior Vice President and Chief Technology Officer, Dr. Gorm Heron.

This presentation focuses on the oldest In Situ Thermal Remediation (ISTR) technology, Steam Enhanced Extraction (SEE).  It is vastly different from the other ISTR methods used, in that steam is generated above-ground and injected through wells, heating the ground while displacing fluids as the steam zone grows.  Since steam tends to follow the more permeable paths, SEE projects require very careful planning and execution.  The presentation covers the most important aspects:

  • Subsurface data need for predicting steam migration and for designing the well-field.
  • Modeling tools and procedures.
  • Equipment needed for SEE implementation.
  • Monitoring – how to keep track of the steam flow and heating progress.
  • Pressure cycling – principles and importance.

These steps are illustrated using recent SEE project examples, including the use of SEE and Thermal Conduction Heating (TCH) as a combination for sites with both permeable, water-bearing zones and tight clay zones.
