Schramm’s recently-introduced Telemast tower system has been a success on two Rotadrill rig models and is now being moved up to the next size drilling rig, the TXD, for deeper drilling capabilities. Schramm introduced the first TXD unit in August.
Both smaller rig models, T90XD and T130XD, are heavy-duty, heavy-hoist, straight-truck-carrier mounted, topdrive drilling rigs. Aside from their respective 90,000-lb and 130,000-lb lift capacities, the T90XD can handle Range-II casing, while the T130XD can handle Range-III casing. All three rigs are classed as shallow oil and gas land drilling rigs suitable for CBM projects.
With a hoist rating of 180,000 lb, the TXD has a greater hoisting capacity than the T130XD or T90XD, 40% and 100% respectively. Some drilling contractors report that their T130XD rigs are drilling to 7,000 ft.
The Telemast is a two-section mast. Section-one is affixed at its base to the drilling rig’s chassis, while section-two is a sliding, extendable section.
