ABSTRACT:
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.
