Eccentric Overburden Casing Drilling ODEX140 system

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.

 

Applications:

Blast holes

Water supply wells

Bridge and building foundations

Standard slant or horizontal drilling

Mining air holes

Environmental monitoring wells

Grouting operations

Seismic shot holes

Soil sample and geotechnical applications

Ground anomaly and tiebacks

Storage caverns and dam
