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.

In one embodiment, a top drive system for drilling with casing is provided with an access tool to retrieve a downhole tool. The top drive system for drilling with casing comprises a top drive; a top drive adapter for gripping the casing, the top drive adapter operatively coupled to the top drive; and an access tool coupled to the top drive and adapted for accessing a fluid passage of the top drive system. In another embodiment, a method for retrieving a downhole tool through a tubular coupled to a top drive adapter of a top drive system is provided. The method comprises coupling an access tool to the top drive system, the access tool adapted to provide access to a fluid path in the top drive system and inserting a conveying member into the fluid path through the access tool.

The invention relates to an apparatus for connecting a control line to a tubular string. In one embodiment, the apparatus includes a guide boom pivotable around a location adjacent the string and with a guide member at an end thereof to guide the control line. The apparatus further includes a clamp boom that is independently pivotable and includes a clamp housing at an end thereof for clamping the control line against the tubular string. The guide boom and the clamp boom each have a center line which is substantially aligned with the center line of the tubing string permitting the control line to be aligned adjacent the tubular string prior to clamping.

A method and apparatus for connecting threaded members while ensuring that a proper connection is made. In one embodiment, the applied torque and/or rotation are measured at regular intervals throughout a pipe connection makeup. When a shoulder contact is detected, a predetermined torque value and/or rotation value is added to the measured torque and/or rotation values, respectively, at shoulder contact and rotation continued until this calculated value(s) is reached.

An axle for removably retaining a wheel on a vehicle. The axle comprises a rotary-type connector at a first end thereof; a cam assembly operatively connected to the second end, the cam assembly including a cam having an axis of rotation; a lever operatively connected to a second end of the axle, said lever being rotatable about an axis substantially parallel to the axis of rotation of the cam, between an open position in which the axle is removable from and mountable on the vehicle and a closed position in which the axle is retained on the vehicle; and a cam assembly operatively connected to the second end; and a lever stop ensuring that an angle of maximum rotation for the lever from the closed position is less than 180 degrees.

Apparatus and methods are provided to prevent an operator from inadvertently dropping a string into a wellbore during assembling and disassembling of tubulars. Additionally, the apparatus and methods may be used to for running in casing, running in wellbore components or for a drill string.
摘要:
The present invention provides a downhole cementing apparatus run into a borehole on a tubular. The apparatus is constructed on the pipe in such a way that pressure surge during run-in is reduced by allowing fluid to enter the pipe and utilize the fluid pathway of the cement. In one aspect of the invention, an inner member is provided that filters fluid as it enters the fluid pathway. In another aspect of the invention, various methods are provided within the cementing apparatus to loosen and displace sediment in the borehole prior to cementing.

The present invention generally provides a method for remotely controlling and/or monitoring at least one parameter of well bore equipment. In one aspect, a method for remotely controlling and/or monitoring at least one parameter of well bore equipment is provided, including: collecting data corresponding to the at least one parameter by a sensor module monitoring the at least one parameter of the well bore equipment; transmitting the collected data to a remote control/monitoring unit via a communication link; analyzing the collected data to determine if the parameter is within predefined limits; if the parameter is not within predefined limits, then transmitting control data from the control/monitoring unit to the well bore equipment for modifying the operation of the well operation equipment so that the parameter will conform to the predefined limits or stopping operation of the wellbore equipment.
