A small, portable topdrive system, which can be installed in as little as 4 hr with little or no derrick modification, can help land rigs drill difficult or extended reach wells, according to Tesco Drilling Technology in Calgary. The units are designed for rigs that must be dismantled and moved after each well. To reduce the amount of derrick modifications, the systems are designed to fit on any rig that can make a conventional kelly connection with a 42-ft kelly and a 31-ft single. The compact unit can operate in tapered area above the monkey board. The first portable skid package went into the field in 1992. In its first 6 months of operation, this unit was installed on six rigs, drilled seven horizontal wells, and operated for about 2,000 hr with only 12.5 hr total downtime.
