Performing simultaneous operations on multiple wellbore locations using a single mobile drilling rig

摘要

A system includes a drilling rig having a substructure, the drilling rig being adapted to be positioned above a plurality of wellbore location such that each of the plurality of wellbore locations is simultaneously positioned below the substructure. Equipment movement means is included for moving pressure control equipment between positions proximate each of the plurality of wellbore locations, the equipment movement means being adapted to move the pressure control equipment between the positions while the drilling rig is performing a rig operation on at least a first one of the plurality of wellbore locations. Equipment positioning means is included for positioning pressure control equipment on one or more of the plurality of wellbore locations, the equipment positioning means being adapted to position the pressure control equipment on a second one of the plurality of wellbore locations while the rig operation is being performed on the first wellbore location.

1. A system, comprising:
a drilling rig comprising a substructure, said drilling rig being adapted to be positioned above a plurality of wellbore location such that each of said plurality of wellbore locations is simultaneously positioned below said substructure, said drilling rig being further adapted to be moved along a line of wellbore locations comprising at least said plurality of wellbore locations; equipment movement means for moving one or more pieces of pressure control equipment between positions proximate each of said plurality of wellbore locations, said equipment movement means being adapted to move at least one of said one or more pieces of pressure control equipment between said positions while said drilling rig is performing a rig operation on at least a first one of said plurality of wellbore locations; and equipment positioning means for positioning said one or more pieces of pressure control equipment on one or more of said plurality of wellbore locations, said equipment positioning means being adapted to position at least one of said one or more pieces of pressure control equipment on a second one of said plurality of wellbore locations while said rig operation is being performed on said first wellbore location.
