Steam Enhanced Extraction

ISTR in Complex Geologic Settings with Highly Variable Permeabilities and High Groundwater Flux Zones

Complex geologies with highly permeable zones can cause significant challenges while heating the subsurface during in situ thermal treatment and those challenges pose a serious threat to your project’s success. It is critical to have a detailed conceptual site model (CSM) and a proper understanding of the site’s lithology before choosing the technologies and designing the remedy that will best address the contaminant(s), the site’s unique complexities, and the outcomes demanded by state and federal guidance.
In this webinar, thermal expert John LaChance discusses the type and nature of high permeability and complex geologic settings, how they affect thermal treatment, and examples of effective in situ thermal remediation (ISTR) designs in complex geologic settings.

ISTR Challenges Part 2: Electrical Resistance Heating and Steam Enhanced Extraction

Thermal Conduction Heating (TCH), Electrical Resistance Heating (ERH) and Steam Enhanced Extraction (SEE) are widely used thermal technologies capable of effectively remediating a variety of chemicals in various varying subsurface settings, yet sometimes operations do not perform as planned.  An experienced thermal remediation contractor can help you anticipate and address site-specific challenges during full-scale thermal projects.

Presented by Vice President of Development, John LaChance and Vice President of Technology, Steffen Griepke, ISTR Challenges Part 2 covers some of the common issues that can arise at ERH and SEE sites, and discuss how they should be addressed.  You’ll hear about scenarios involving

  • significantly different soil electrical resistivities than planned
  • slower than expected heat-up
  • stray voltages and currents
  • poor steam quality
  • higher than expected mass removal rates
  • lack of hydraulic control
  • non-uniform steam delivery and heating

Join the discussion for insight to help avoid costly project delays in your next thermal project.

What is Steam Enhanced Extraction (SEE) and How is it Applied?

Although Steam Enhanced Extraction (SEE) may not be the most common thermal remediation technology, it is the go-to approach for heating and treating sites with high permeability and groundwater flux. Did you know it’s also the most cost-effective way to input energy into the subsurface?

In this 30-min webinar, two thermal remediation experts will give you an overview of SEE. You will learn:

  • How SEE works,
  • What geologic conditions it is best suited for,
  • Design considerations to ensure a successful SEE project,
  • SEE sweet spots, and
  • Examples of SEE projects.

VP of Technology, Steffen Griepke and Senior Project Engineer, Nikole Huard, will answer your questions about using SEE to remediate sites.
