Side saddle substructure
The drilling rig includes a first substructure and a second substructure. The second substructure is positioned generally parallel to and spaced apart from the first substructure and generally the same height as the first substructure. The drilling rig further includes a drill rig floor coupled to the first and second substructures, where the drill rig floor positioned substantially at the top of the first and second substructures.
1. A box-on-box land based drilling rig comprising:
a first elongated substructure;
a second elongated substructure, the second elongated substructure being positioned generally parallel to and spaced apart from the first elongated sub structure;
a drill rig floor fixedly coupled to the first and second elongated substructures; and
a mast coupled to the drill rig floor, wherein the mast further comprises a V-door side and wherein the V-door side of the mast is perpendicular to a long axis of the first elongated substructure,
wherein the box-on-box land based drilling rig is adapted to be traveled in an assembled state through a wellsite.
2. The land based drilling rig of claim 1 , further comprising a choke manifold, the choke manifold positioned on the drill rig floor.
3. The land based drilling rig of claim 2 , wherein a catwalk is coupled to the first elongated substructure or second elongated substructure and is adapted to travel with the land based drilling rig.
4. The land based drilling rig of claim 1 , wherein the land based drilling rig is a box-on-box rig.
5. The land based drilling rig of claim 1 , wherein the drill rig floor comprises a V-door, the V-door generally aligned with a V-door side of the drill rig floor, the V-door side of the drill rig floor aligned perpendicular to a long axis of the first elongated substructure.
6. The land based drilling rig of claim 1 further comprising one or more tanks, the one or more tanks positioned within the land based drilling rig.
7. The land based drilling rig of claim 1 further comprising a mud gas separator, the mud gas separator positioned within the first elongated substructure or the second elongated substructure.
8. The land based drilling rig of claim 1 further comprising a pipe handler, the pipe handler positioned to carry piping through a V-door on the V-door side of the drill rig floor.
