Multifunctional Casing Advance Drilling / Downhole Casing Cutter
Casing Advance Drilling Introductions:
Roschen 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.
The integral operation makes the Roschen Casing Advancer eminently suitable for drilling through overburden or sands and gravels.
It is also particularly suitable for Landfill Drilling applications.
Casing Advance Drilling Advantage:
1. Enhance penetration and perpendicularity
2. Reduce torque requirements
3. Deal with straight, oblique hole and other angle holes
4. Lowest effect with environment
Casing Advance Drilling Applications:
1. Soil sampling and overburden coring in conjunction with casing.
2. Casing through difficult overburden or formations.
