Technical FAQs
What is the purpose of surface casing?
Surface casing provides blowout protection, isolates water sands, prevents lost circulation, and offers adequate shoe strength for drilling into high-pressure transition zones.
How much PSI is required for air tools?
Most air tools operate effectively between 70 and 90 PSI. Ensure your compressor supplies adequate air volume for optimal tool performance.
