An important consideration in process development for in situ coal gasification is a means of measuring resource utilization and the location of the active combustion front by remote sensing. Efforts to develop measuring techniques applicable both during and after completion of a test burn have been underway at LERC for the past two years. Existing technology applied to post-burn evaluation has consisted of wire line drilling and coring, and conventional reflection seismic surveying. Research is underway to evaluate shear wave seismic surveying, high resolution shallow reflection seismic surveying, magnetic surveys to detect changes in iron minerals in the over burden as they are heated, and seam wave seismic surveys as means of real-time evaluation for process monitoring and control.
