The Land Service Rigs are used by the Oil companies to complete the new wells drilled by the land drilling rigs and also to perform maintenance on the existing wells. Generally all the existing wells will experience decline in the production rates due to many reasons, such as sand accumulation, water migration, severe corrosion of the tubing and leaks in well-completion equipment and so on.

Well maintenances are ongoing as long as the oil companies keep the wells in production. These wells are revisited regularly using the service rigs to perform various task such as well clean out, running new completion, side tracking and fishing. A Service rig also operates 24 hours a day and will require about 25 crew members to operate.

COE currently has one 600 Hp Service Rig which is of the new generation rig with fast moving and rig up concept. The unit was built in Canada and would be ready to commence work during 3rd quarter 2008.
