Description

The performance of pressure-pulse transducers in determining distances of installed gages from small H.E. detonations by measuring seismic wave travel times was evaluated. Because of the superiority of the system time resolution as compared with conventional geophysical exploration equipment, improved accuracy was anticipated as well as an opportunity to dry-run the installed system in the operational environment. Also, a requirement for seismic velocity measurements in situ was fulfilled. Travel time measurements used satellite-hole gage placements, 5-pound C-4 detonations near the planned location of the device in the device hole, and operational diagnostic facilities. The results verified the original premise of ... continued below

Description

The performance of pressure-pulse transducers in determining distances of installed gages from small H.E. detonations by measuring seismic wave travel times was evaluated. Because of the superiority of the system time resolution as compared with conventional geophysical exploration equipment, improved accuracy was anticipated as well as an opportunity to dry-run the installed system in the operational environment. Also, a requirement for seismic velocity measurements in situ was fulfilled. Travel time measurements used satellite-hole gage placements, 5-pound C-4 detonations near the planned location of the device in the device hole, and operational diagnostic facilities. The results verified the original premise of the suitability of Plowshare instrumentation to determine with superior accuracy installed gage distances from the small H.E. detonations. Agreement of within 1% between surveyed distances and calculated distances was obtained for the three gage locations reporting. Seismic velocities obtained fell between 3825 amd 3875 feet per second. Also, the experiment demonstrated the integrity of the Plowshare instrumentation system as installed. (auth)
