Sonic Drilling

The sonic rig, one more item keeping Traut a leader.

The SV100 Versa Sonic drill rig is equipped with a specially designed sonic vibratory drill head. This drill head combines rotation with high-frequency vibration to advance the drill pipe. Sonic vibrations are transmitted down the drill pipe to the drill bit causing surrounding soil particles to fluidize, allowing for penetration. Core sampling is done ahead of the outer casing. Once the 4” core barrel is advanced to its desired depth, an outer drill pipe is then advanced outside the core barrel to keep the borehole open. Prior to each core sample run, the 6” 8” or 10” outer casing is sealed off, preventing cross-contamination and formation mixing. The core barrel is then removed from the borehole, and the sample is extracted into a plastic sleeve.

With the Sonic rig, we can core in all of the following formations:

• Unconsolidated Soils
• Clays
• Cobbles and Boulders
• Shale
• Sandstone
• Mudstone
• Limestone
• Granite and other bedrocks
• Landfill Debris
• Concrete

The greatest advantage of Sonic Drilling is its ability to obtain large volumes of undisturbed continuous core samples. This provides a detailed, inch by inch analysis for engineers. Core samples can be stored and transported in the sleeve, or cut open on site to photograph and log. Sonic Drilling provides a precise and detailed profile of any soil conditions.

Types of Projects
1. Site assessments
2. Underground storage tank investigation
3. Delineation of contaminants prior to remediation or excavation
4. Installation of monitoring and recovery wells
5. Geotechnical investigations
6. Mineral & sand exploration
7. Steel pile
8. Hydro profiling, a method to obtain discreet, zone specific water samples while drilling

Capabilities
1. Years of experience
2. Quick and easy setup
3. Setup done with minimal distance behind the borehole
4. 4” Core sample for unconsolidated soil
5. 3 ½” Double wall core barrel for bedrock sampling
6. 3” Diamond core
7. 6”, 8” and 10” Casing liners for confining layers
8. 2”, 4”, 6” and 8” Well installations
9. Hydro Profiling
10. Ability to contain drill fluids and soils
11. Air or mud rotary drilling
12. Overshoot well casing abandonment
13. Portable decon pad for drill rig & casing
14. Depths up to 500 feet

Advantages
1. Conduct continuous sampling
2. Preserve the integrity of the sample
3. Converts easily and quickly to a rotary or diamond core
4. Eliminates cross contamination of aquifer with 6”, 8” and 10” liners
5. Surrounding soil is undisturbed
6. Yield higher precision analysis
7. Drill faster / save time and money
