CASING DRILLING® SERVICES

What is CASING DRILLING® Technology?

TESCO, has invested $25 million and five years of intensive research and development in elevating the revolutionary CASING DRILLING® process from an experimental procedure to a proven success. The CASING DRILLING® process uses standard oilfield casing to drill the well and then leaves it in place to case the well. This process makes it possible to speed up drilling 20 to 30 percent or more, by eliminating drill-string tripping and the problems associated with it. Drill bits and other downhole tools are lowered and retrieved via wireline inside the casing and latched to the bottom-most joint of casing. This safer and more efficient process will change forever how wells are drilled.

Almost any drilling rig can be adapted to use TESCO's CASING DRILLING® technology. Rigs with existing top drive systems are readily converted, either permanently or temporarily, by installing a wireline system for running and retrieving the drilling tools. Portable TESCO Top Drive Drilling Systems can be easily installed on rigs without top drives. Converted rigs lose none of their conventional capabilities.

CASING DRILLING® delivers all of the functionality of conventional drillpipe drilling, including:

* Vertical or directional;
* Steerable motor assemblies
* Rotary steerable systems;
* Logging while drilling;
* Coring;
* Retrievable or non-retrievable systems.

TESCO is the industry leader in providing CASING DRILLING® technology, and is the only provider of a complete offering including equipment, planning and engineering services including well programming, and field supervision and project management services.
