Abstract:
1. A control system for operating a transportable well completion system for use in moving pipe into and out of a wellbore, comprising: a rig carrier operable to transport at least a portion of said transportable well completion system; a mast assembly pivotally mounted to said rig carrier; a top drive mounted in said mast assembly, said top drive being operable for moving said pipe up and down in said mast assembly; a skid; a pipe handling system mounted to said skid, said pipe handling system being operable for moving pipe for connection with said top drive within said mast assembly and for receiving pipe from said top drive for movement of said pipe away from said mast assembly; a pipe tub for storing pipe; a pipe transfer system operable for moving pipe from said pipe tub to said pipe handling system and for moving pipe from said pipe handling system to said pipe tub; a pipe tong aligned with said top drive mounted in said mast assembly operable for connecting pipe together for moving said pipe into said wellbore and for disconnecting pipe for removal of said pipe from said wellbore; and at least one computer configured to control said pipe transfer system for moving pipe from said pipe tub to said pipe handling system and for moving pipe from said pipe handling system to said pipe tub, said at least one computer being configured to control said pipe handling system for moving pipe to said mast assembly and away from said mast assembly, said at least one computer being configured to control said top drive for moving pipe up and down within said mast assembly and for positioning said pipe with respect to said pipe tong and for operating said pipe tong for connecting said pipe together to move said pipe into said wellbore and for disconnecting said pipe for removal of said pipe from said wellbore, wherein said movement of said pipe into said wellbore is coordinated with said top drive and said pipe tong by use of said at least one computer, and wherein said at least one computer operates said pipe handling system in real time to perform functions automatically by calibrating certain movements of said pipe handling system and said top drive mounted in said mast assembly.
