Frequently Asked Questions
What is casing design?
Casing program design involves selecting setting depths, casing sizes, and steel grades that enable safe drilling and completion of wells to desired production configurations.
How does a casing advancer work?
The Casing Advancer allows simultaneous drilling and casing as a single integrated operation. This design saves time and effort by eliminating the need to remove drill rod strings and rock bits from large diameter holes before reaming casing back into position.
How far can you directional bore?
Maximum crossing lengths and hole diameters depend on specific geotechnical conditions. For heavy rig horizontal directional drilling, the effective outside range is typically up to 3,000 meters.
