New motors solve UBD and HPHT problems
- Rotech Holdings Ltd., Aberdeen (United Kingdom)
There are two particular areas where industry contractors have been pushing current downhole motor technology to the limits of its capabilities--high temperature (HPHT) and underbalanced (UBD) operations. Economic incentives for slimhole, short-radius re-entry and multilateral wells have been well established, but until recently, the options for this kind of work have been limited. The increased use of coiled tubing has introduced additional challenges for motor manufacturers, with greater emphasis on shortness for ease of rig-up and steerability. These challenges are addressed by a unique new motor that promises benefits for coiled tubing drilling, re-entry work and multilateral drilling, as well as for geothermal wells.
