Geoprobe Sonic® 8150LS

The Geoprobe® 8150LS is a powerful, safe, efficient, and accurate full size rotary sonic rig. Capable of working with tooling diameters of up to 12”. It delivers big sonic power, with head energy equivalent to the largest produced by any sonic rig manufacturer, to advance large diameter tools to greater depths and to complete complex holes. Capable of setting casing in excess of 300’ in a wide range of formations. Continuous samples can be collected in multiple geologic formations, including consolidated materials, flowing sands, coal ash, glacial till, and backfill rubble.

  • 50,000 lbf head @ 150 hz
  • Casing Sizes: 12”, 10”, 8”, 6”, 5”, 4.5” & 3”
  • 8 x 10, 6 x 8, 4 x 6 Sonic Sampling
  • 4”, 6” & 8” core barrels for soil and rock coring
  • Discrete Interval Water Sampling Technology with use of stainless-steel screen and inflatable packers
  • DH104 Auto Hammer for SPT
  • High speed rock coring head – quick transition from sonic drilling / sampling to conventional rock coring with same rig.
  • Automated Rod Handler for hands free rod string tool mating
  • Weighted wireline sampler. This system allows for more rapid core barrel collection as well as eliminating the need for the crew to trip any rods during each 10’ sample extraction, increasing efficiency while decreasing fatigue. In theory, this system should also provide improved sample preservation due to the fact that the sample core barrel is isolated from the high-frequency vibration generated in the sonic head and transmitted down the outer casing string.
