Carbon Energy  has released the results of a survey that confirms the size and nature of the Underground Coal Gasification (UCG) cavity following trials of the Company’s proprietary keyseam UCG technology.

The independent electro-seismic survey was conducted by Aquatronic Solutions, developers of this innovative technique at the Company’s Bloodwood Creek pilot site.

Aquatronic Solutions produced an image of Carbon Energy’s UCG cavity following the decommissioning of the Company’s Panel 2 at the site. The image was created by detecting the heated rock in the roof of the cavity.

The Bloodwood Creek Panel 2 UCG reactor was operated continuously for 20 months and gasified approximately 13,000 tonnes of coal, forming a cavity of approximately 8,500m³ in size. In March 2012 Carbon Energy announced that Proof of Concept was achieved during the Panel 2 trial, including the following key outcomes:

  • High quality syngas produced – a 12-month average of 6.45 MJ/Sm³ HHV
  • Consistent gas quality
  • No physical intervention or re-ignition required once reactor initiated
  • No impact on groundwater quality or quantity beyond trial area
The location of the reactor cavity is clearly shown and confirms:

  • Containment and control of the gasification process, evidenced by the limited gasification impact outside the defined panel
  • Predictability and validation of the Company’s gasification prediction models
  • Cavity size and location is in line with expectations
  • Company’s patented, automated CRIP system operates effectively
The electro-seismic method also allows for continuous monitoring of the reactor growth during the gasification process. When Carbon Energy’s keyseam technology operates, the size, shape, and location of the cavity can be monitored to confirm it is performing in-line with expectations.

Acting CEO for Carbon Energy, Morné Engelbrecht said the survey was an exciting development as it once again proved the technically advanced nature of the Company’s proprietary keyseam UCG technology.

According to Mr Engelbrecht, the survey concluded that Carbon Energy’s keyseam technology operated in a manner consistent with expected outcomes, adding that the latest findings further support one of their key strategic pillars, which is to pursue global expansion by becoming the preferred partner of choice, nationally and internationally through the delivery of technically advanced and demonstrated UCG technology.
