Casing Advancer For Soil Sampling And Overburden Coring

Casing drilling involves drilling and casing a well simultaneously through unstable ground conditions, In casing drilling process, down the hole tools can be retrieved, through the casing on wire-line, meaning tool recovery or replacement of tools can take minutes versus hours under conventional methods. This process employs wire line-retrievable tools and a drill-lock assembly, permitting bit and BHA changes, coring, electrical logging and even directional or horizontal drilling
