Patent number: 9915111Abstract: A system and method are disclosed for drilling a well and obtaining a downhole core sample. A drilling rig includes a pivotal mast. The mast supports an injector thereon with an injector axis offset with respect to the central axis of the mast when the drilling rig is handling threaded tubular. The mast also supports a drive unit. A drilling assembly includes coil tubing, the injector, and a bottomhole assembly including a percussion tool suspended in the well from the coil tubing. A coring assembly includes a threaded tubular string and the drive unit supported on the mast for rotating the threaded string and the coring bottomhole assembly while the injector is spaced from the axis of the mast.Type: GrantFiled: February 3, 2011Date of Patent: March 13, 2018Assignee: Xtreme Drilling and Coil Services Corp.Inventors: Denis Rousseau, Jeremy Myers, Richard Havinga

Patent number: 9745814Abstract: A method and/or system is provided for milling an opening into a tubular positioned in a well bore using coiled tubing. Surface equipment includes a programmable controller at the surface, which is utilized for controlling an injector motor so that an encoder for monitoring movement of said coiled tubing string produces less than a predetermined maximum number of pulses for a given time interval.Type: GrantFiled: September 2, 2011Date of Patent: August 29, 2017Assignee: Xtreme Drilling and Coil Services Corp.Inventors: Reginald W. Layden, Gary Joseph Werner

Patent number: 8887800Abstract: A coil tubing rig (12) is supported on a carrier trailer (24) in transit and during rig operations. A plurality of a hydraulic tracks (30), (32) each connected to the carrier trailer may be activated to raise and lower the carrier trailer from the loading position to a rig operating position. A dolly assembly including a plurality of wheels supports the carrier trailer during transit, and hydraulic jacks both incline the carrier trailer to a rig loading/unloading position such that a front end of the carrier trailer is substantially at ground level, and raise the rig to a desired elevation for conducting rig operations.Type: GrantFiled: December 30, 2010Date of Patent: November 18, 2014Assignee: Xtreme Drilling and Coil Services CorpInventors: Richard D. Havinga, Reginald Layden

Patent number: 8763683Abstract: A control circuit for a coiled tubing injector includes a circuit controller (14). One or more counterbalance vales (3) may be responsive to the circuit controller to prevent the tubing string from descending into the wellbore during rate of penetration movement. In one embodiment, a control valve (4) allows fluid to flow through a bypass line around the counterbalance valves when drilling in a weight-on-bit mode. Other hydraulic control circuits allow for the release of fluid pressure to control the injector hydraulic motor. In yet another embodiment, the control circuit regulates power to an electric motor of the injector.Type: GrantFiled: November 6, 2012Date of Patent: July 1, 2014Assignee: Xtreme Drilling and Coil Services Corp.Inventor: Richard Havinga
