Heat Treated Casing Drilling System / Water Well Drilling Oil Casing Pipe
 
Casing Drilling System Introduction
 

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. Once the casing point is reached, the casing is

cemented in place without tripping pipe.

Casing drilling has been employed in many countries as an effective method of reducing the overall drilling costs by reducing drilling time and drill string problems encountered during conventional drilling process.

Casing Drilling System Applications:

• Soil sampling and overburden coring in conjunction with casing.
• Casing through difficult overburden or formations.
