Frequently Asked Questions
What is casing design? The design of a casing program involves selecting setting depths, casing sizes, and steel grades that allow for safe drilling and completion of wells to desired producing configurations.
How does a casing advancer work? The Casing Advancer allows drilling and casing to be performed simultaneously as one integral operation, eliminating the need to drill with a rock bit, pull the drill string, and then ream casing back into the hole.
How far can you directional bore? Maximum lengths and hole diameters depend on specific geotechnical conditions, with effective outside range for heavy rig horizontal directional drilling up to 3,000 meters.
