RFQ:
1. What is casing design?
The design of a casing program involves the selection of setting depths, casing sizes and grades of steel that will allow for the safe drilling, and completion of a well to the desired producing configuration.
2. How does a casing advancer Work?
The Casing Advancer has been designed to allow drilling and casing to be carried out at the same time as one integral operation. This feature eliminates the need to drill the large diameter hole with a Rock Bit, pull the drill rod string and Rock Bit from the hole and then ream the casing back into the hole.
3. How far can you directional bore?
What are the minimum and maximum lengths of crossing? Maximum lengths and hole diameters are determined by project specific geotechnical conditions however effective outside range for heavy rig horizontal directional drilling is 3,000m
