LLL instrumentation for in situ coal gasification. [16 refs]
Hoe Creek, Wyoming, was the site for Lawrence Livermore Laboratory's first in situ coal gasification experiment in the fall of 1976. The water-saturated coal seam had been fractured by explosives the previous year. We developed an instrumentation program to measure the burn movement, the dewatering activities, and the surface-process parameters. The primary diagnostic subsurface instruments were numerous type K grounded, sheathed thermocouples. Subsurface bubbler tubes, terminating at the surface with pressure transducers, followed water-table movement during dewatering. Data acquisition was accomplished primarily with a Vidar/Accurex 5403 Digital Data Logger. Plans are included for proposed instrumentation for the Hoe Creek No. 2 Coal Gasification Experiment in summer and fall, 1977. Designs for Hoe Creek No. 2 have been modified using data from Hoe Creek No. 1.
