Well Retrofit Solutions to Leverage Unproductive or Degraded Wells

Using GreenLoop technology, our Well Retrofit Solutions are tailored with a flexible system of components and processes that can be employed in a variety of configurations to optimize geothermal power production for a variety of well conditions.

GreenFire Energy Well Retrofits can produce power from marginal wells with these issues:

• Insufficient or intermittent brine flow
• Insufficient wellhead pressure
• High levels of non-condensable gases

Each Well Retrofit is individually engineered using proprietary modeling tools to assess and remediate the issues of a specific well. The resulting system maximizes power generation for the enthalpy, diameter, depth, brine and flow characteristics of the well. Typically, steam is delivered to the existing low or high pressure systems, but power can also be generated by a matched turbo-expander/generator installed at the top of each retrofit well. Groups of similar unproductive wells offer additional opportunities for Well Retrofits with even more attractive economic returns.

Well Retrofit Solution Benefits

• Economic use of unproductive wells to become productive
• Fast deployment in approximately 6 months
• Low risk as no drilling, additional permitting or modifications to power purchase agreements are required
• Predictable results based on the modeling of an optimized solution
• Improved profitability and ROI
• Cost competitive with other renewable technologies
• Estimated payback in 2 years

Field Scale Solution Unlocks a Vast Source of Clean, Continuous Energy

Geothermal energy offers the clean, continuous, power that large customers demand, but its vast potential has been constrained by the limitations of conventional technology. In contrast, our Field Scale Solution with GreenLoop technology enables geothermal companies to exploit quality geothermal resources in many more regions of the world. GreenLoop is an enhanced version of the the drilling and completion technology that revolutionized the oil and gas industry to develop large new geothermal projects anywhere there is sufficient heat.

GreenLoop not only opens up vast but previously unusable geothermal resources but uses existing geothermal resources more intensively. GreenLoop’s high well density architecture extracts much more heat than conventional technology which, on average, uses only about 10% of the heat available in a typical geothermal project. Drilling multiple wells in the same location substantially reduces the cost per well and permits economies of scale in site development, power purchase agreements, and transmission lines.

GreenFire Energy’s extensive project modeling capability for closed-loop projects reduces project risk and optimizes power output. GreenLoop technology is the product of years of research conducted in concert with the U.S. Department of Energy, National Laboratories, major universities, and eminent experts in a wide spectrum of oil and gas drilling, geology, modeling, and thermodynamics disciplines.
