Publication number: 20120128432Abstract: The invention relates to an ice worthy jack-up rig that may extend the drilling season in shallow water off shore Arctic or ice prone locations. The inventive rig would work like a conventional jack-up rig while in open water with the hull jacked up out of the water. However, in the event of ice conditions, the legs are held in place by cans embedded in the sea floor to resist lateral movement of the rig and the hull is lowered into the water into an ice defensive configuration. The hull is specifically shaped with an ice-bending surface to bend and break up ice that comes in contact with the hull while in the ice defensive configuration.Type: ApplicationFiled: October 21, 2011Publication date: May 24, 2012Applicant: ConocoPhillips CompanyInventors: Peter G.

Publication number: 20120061087Abstract: A method for drilling a wellbore includes drilling the wellbore by injecting drilling fluid into a top of a tubular string disposed in the wellbore at a first flow rate and rotating a drill bit. The tubular string includes: the drill bit disposed on a bottom thereof, tubular joints connected together, a longitudinal bore therethrough, a port through a wall thereof, and a sleeve operable between an open position where the port is exposed to the bore and a closed position where a wall of the sleeve is disposed between the port and the bore. The method further includes moving the sleeve to the open position; and injecting drilling fluid into the port at a second flow rate while adding a tubular joint(s) to the tubular string. The injection of drilling fluid into the tubular string is continuously maintained between drilling and adding the joint(s).Type: ApplicationFiled: September 7, 2011Publication date: March 15, 2012Applicant: Weatherford/Lamb, Inc.Inventors: David Iblings, Thomas F.

Publication number: 20120061144Abstract: A drill rig (10) comprises a tower (12) and a drill head (14) that is able to travel linearly up and down the tower (12). The drill head (14) provides torque to a drill string (16) attached to the drill head (14) ad thus to a drill bit (18) coupled to a distal end of the drill string (16). The drill head (14) is traversed along the tower (12) by a plurality of rams (22a, 22b) and (22c) (hereinafter referred to in general as “rams 22”). The rams (22) provided hold back and pull down for the drill bit (18) via the drill head (14). The rams (22) are selectively operable to enable the hold back and pull down applied to the drill bit to be selectively varied. Thus for example a first of the rams (22a) is selected to operate when drilling to a first depth, then the rams (22b) and (22c) are selected to operate when drilling to a second greater depth; and finally all three rams (22a, 22b) and (22c) are selected to operate when drilling to a third greater depth.Type: ApplicationFiled: March 19, 2010Publication date: March 15, 2012Applicant: STRANGE INVESTMENTS (WA) PTY LTDInventor: Warren Strange

Publication number: 20120061143Abstract: A managed bulk drilling system that employs a guide wire for ranging and crosswell telemetry. Some system embodiments include multiple drilling assemblies operating in the vicinity of a reference well that contains an electrical cable. The electrical cable is coupled to a surface control system. The control system uses the electrical cable as part of an antenna to receive uplink signals from the drilling assemblies and to broadcast down-link signals to the drilling assemblies. The uplink signals can include position data and the downlink signals can include individual steering commands to adjust the trajectories of each drilling assembly. The cable can also generate a guidance field for the drilling assemblies to detect and follow.Type: ApplicationFiled: June 1, 2009Publication date: March 15, 2012Applicant: Halliburton Energy Services, Inc.Inventor: Richard T.

Patent number: 8132631Abstract: There is provided a method for drilling a hole into the ground and installing a geothermal transfer loop. A drilling apparatus is positioned at a desired location. The drilling apparatus includes a rotating and vibrating apparatus, such as a sonic drill, for rotating and vibrating a hollow drill string into the ground. The hollow drill string having an inner space. A hole is drilled to a desired depth by rotating and vibrating the hollow drill string into the ground while discharging fluid into the inner space of the hollow drill string. The fluid forming a fluid column in the inner space of the drill string. The fluid column impedes entry of ground materials into the inner space of the drill string and is vibrated to create a water hammer for adding an additional drilling force. A geothermal transfer loop is lowered into the inner space of the hollow drill string and the drill string is removed from the ground. The method may also include discharging grouting material into the hole.Type: GrantFiled: October 31, 2007Date of Patent: March 13, 2012Inventor: Raymond J. Roussy
