ABSTRACT:
A cantilevered drilling structure including a base unit having a side positionable generally adjacent a well head, and a drilling rig mast assembly positioned generally above and supported by the base unit. The base unit has a cantilever member extending out from its side, spaced from the ground, and having an outer portion spaced from the side. A telescoping leg extends down from the outer portion and is spaced from the side such that the side and the leg are positionable on opposite sides of a well head. The telescoping leg is movable between a lower support position and a higher raised position high enough to pass over flow lines when the drilling structure is moved along the well row. A skidding floor mechanism moves the drilling rig mast assembly along the base unit between a drilling position over the cantilever member when the telescoping leg has been extended and a moving position closer to the center of gravity of the base unit. When the drilling rig mast assembly is in its moving position and the telescoping leg in its higher raised position, the drilling structure can be rolled on a wheel assembly to a new location, for example, between two existing wells.
