Recently Southwest Exploration was requested to do some underground geophysics locally in Arizona. Pictured below is the result of putting our minds together to create an underground sled rig. The sled rig is small and compact enough to fit into the confined spaces of an underground shaft and mine workings. It is outfitted with a 1HP winch and approximately 4000 ft. of cable. The sled rig is able to support all of our standard logging tools from the SPT Gyro and Acoustic/Optical Televiewers to the latest NMR/BMR technology. It has already completed logging at a depth from 4200 ft. to the 7000 ft. level of a deep underground mine in Arizona. It is ready to service your underground geophysics needs!
