| 20080264648 | APPARATUS AND METHODS FOR TUBULAR MAKEUP INTERLOCK - Apparatus and methods are provided to prevent an operator from inadvertently dropping a string into a wellbore during assembling and disassembling of tubulars. In one embodiment, an interlock system is used to control the operations of a gripping apparatus connected to the top drive and a spider such that at least one of the top drive or the spider retains the tubular. The interlock system allows the spider to open when the gripping apparatus is supporting a load of the tubular or is in position to support a load of the tubular. | 10-30-2008 |
| 20080308281 | CONTROL LINE RUNNING SYSTEM - A control line running system includes a control line storage unit and a guiding system having a guiding device and a guide rail for guiding a control line from the control line storage unit toward a well center. The system may also include a control line manipulator assembly for moving the control line toward a tubular and a control line clamp for attaching the control line to the tubular. | 12-18-2008 |
| 20090095488 | APPARATUS AND METHOD FOR FACILITATING THE CONNECTION OF TUBULARS USING A TOP DRIVE - An apparatus and method for facilitating the connection of tubulars using a top drive and is, more particularly but not exclusively, intended for facilitating the connection of a section or stand of casing to a string of casing. | 04-16-2009 |
| 20090101332 | METHOD AND APPARATUS FOR DRILLING WITH CASING - Methods and apparatus for drilling with a top drive system are provided. In one aspect, the present invention provides for a top drive system having includes a top drive, top drive adapter, and a tubular positioning apparatus. In one another aspect, the system includes a telescopic link system connected to a lower portion of the top drive adapter to move the casing string into engagement with the top drive adapter. In another aspect, the top drive adapter includes a housing operatively connected to the top drive and a plurality of retaining members disposed in the housing for gripping the tubular. In another aspect, the tubular positioning apparatus includes a gripping member for engaging a tubular and a conveying member for positioning the gripping member. A spinner may be provided to rotate the tubular. | 04-23-2009 |
| 20090110535 | REMOTELY OPERATED SINGLE JOINT ELEVATOR - A remotely operated joint elevator for use in handling a tubular is provided. The single joint elevator including a housing having an access opening configured to receive the tubular. The single joint elevator further including at least one closure member connected to the housing via a hinge pin. Additionally, the single joint elevator including a power assembly configured to rotate at least one closure member around the hinge pin to selectively open and close the access opening. In another aspect, a method of handling a tubular using a remotely operated joint elevator is provided. In yet a further aspect, a remotely operated joint elevator for use in handling a tubular. | 04-30-2009 |
| 20090218090 | METHOD AND APPARATUS FOR CONNECTING TUBULARS USING A TOP DRIVE - An apparatus for facilitating the connection of tubulars, said apparatus comprising a winch, at least one wire line, and a device for gripping the tubular, the arrangement being such that, in use, the winch can be used to winch said at least one wire and said device to position a tubular below said top drive. | 09-03-2009 |
| 20100051257 | METHODS AND APPARATUS FOR CONNECTING TUBULARS USING A TOP DRIVE - A connection apparatus for coupling a top drive to a tubular gripping member comprises a body having a first joint coupled to the top drive and a second joint coupled to the tubular gripping member, wherein the body is adapted to allow fluid communication between the top drive and the tubular gripping member and to allow relative movement between the top drive and the tubular gripping member. | 03-04-2010 |
| 20100147534 | APPARATUS AND METHOD FOR FACILITATING THE CONNECTION OF TUBULARS USING A TOP DRIVE - An apparatus and method for facilitating the connection of tubulars using a top drive, more particularly but not exclusively, intended for facilitating the connection of a section or stand of casing to a string of casing. | 06-17-2010 |
| 20100224376 | METHOD AND APPARATUS FOR CONNECTING TUBULARS USING A TOP DRIVE - An apparatus for facilitating the connection of tubulars, said apparatus comprising a winch, at least one wire line, and a device for gripping the tubular, the arrangement being such that, in use, the winch can be used to winch said at least one wire and said device to position a tubular below said top drive. | 09-09-2010 |
| 20100230092 | APPARATUS AND METHODS FOR FACILITATING THE CONNECTION OF TUBULARS USING A TOP DRIVE - An apparatus for facilitating the connection of tubulars using a top drive, the apparatus comprising a supporting member connectable to said top drive characterized in that it further comprises an internal tool for engaging said tubular and an external clamping device for engaging said tubular. | 09-16-2010 |
| 20100243273 | TORQUE SUB FOR USE WITH TOP DRIVE - A torque sub for use with a top drive is disclosed. A method of connecting threaded tubular members for use in a wellbore includes operating a top drive. The top drive rotates a first threaded tubular member relative to a second threaded tubular member. The method further includes measuring a torque exerted on the first tubular member by the top drive. The torque is measured using a torque shaft rotationally coupled to the top drive and the first tubular. The torque shaft has a strain gage disposed thereon. The method further includes wirelessly transmitting the measured torque from the torque shaft to a stationary interface; measuring rotation of the first tubular member; compensating the rotation measurement by subtracting a deflection of the top drive and/or the first tubular member; determining acceptability of the threaded connection; and stopping rotation of the first threaded member when the threaded connection is complete or if the threaded connection is unacceptable. | 09-30-2010 |
