Technical Applications
Casing Drilling Explained
Casing is a large diameter pipe inserted into drilled boreholes to protect and support the wellstream, similar to spinal bones protecting the spinal cord.
Percussion Drilling Benefits
This proven technique allows casing insertion to prevent borehole collapse, enabling deep drilling while maintaining progress efficiency.
Air Tool Requirements
Most air tools operate effectively between 70-90 PSI. Ensure your compressor exceeds these requirements for optimal tool performance.
