| 20080202751 | Methods and Devices for Forming a Wellbore with Casing - An example of a method for cementing a casing within an earthen formation includes the steps of providing a gripping mechanism connected to a cementing assembly and a top drive; gripping the casing with the gripping mechanism; sealingly engaging the casing with a seal member; moving the casing to a position within the formation; and cementing the casing within the formation while maintaining a gripping and sealing engagement of the casing. The step of cementing may also include the step of remotely releasing a plug into the casing from the cementing assembly. | 08-28-2008 |
| 20090056930 | Adjustable Pipe Guide For Use With An Elevator and/or A Spider - One embodiment provides an adjustable guide | 03-05-2009 |
| 20090057032 | Segmented Bottom Guide for String Elevator Assembly - The present invention is directed to a segmented bottom guide for directing the top of a tubular member into and through a bore in the bottom of a tapered bowl so that the tubular member can be engaged by pipe slips. One embodiment of the segmented bottom guide of the present invention comprises a bottom guide retainer having a plurality of chambers for being disposed intermediate the top of a bell guide and the bottom of the tapered bowl. The bottom guide segments are radially received into, and securable in, the retainer to therein and together form a generally conical frustum generally aligned with and intermediate the top of the bell guide and the opening of the tapered bowl. | 03-05-2009 |
| 20090101331 | Stabilizer for pipe handling equipment - A stabilizer to suppress unwanted pivotal movement in pipe handling equipment suspended from bails. The stabilizer can contain either or both adjustable contacting members and non-adjustable contacting members which are rigidly connected to a portion of the pipe handling equipment. The adjustable contacting members contact the bails on one or both sides of the bail(s) to suppressing motion of the elevator relative to the bail. | 04-23-2009 |
