Drilling Rig

Abstract

Methods and systems are disclosed for a drilling rig that includes a mast, such as a telescoping mast. The mast has at least three sections, namely a top section, one or more intermediate sections that constitute the intermediate section, and a bottom section. Further, the drilling rig also includes a substructure that is removably attached to the mast. That is, the drilling rig may be attached at its bottom section to the drill floor of the substructure, which has components on and below it. The drill floor has an adjustable height through contact with at least one power source, such as mechanical (e.g., hydraulic, pneumatic, etc.), electrical, and combinations thereof. Further still, the drilling rig is transportable in a single load as opposed to having to transport the drilling rig on multiple loads on multiple trucks.

         8 . The drilling rig of  claim 6 , wherein the substructure further comprises a member selected from a group consisting of a driller's cabin, a tool house, and combinations thereof located on one or more cantilevered beams. 
     
     
         9 . The drilling rig of  claim 1 , wherein the at least one power source is connected integrally, externally or both to the substructure, and wherein the at least one power source is mechanical, electrical, or combinations thereof. 
     
     
         10 . The drilling rig of  claim 1 , wherein the substructure further comprises legs having first ends and second ends, wherein the first ends are connected to the drill floor, and a first set of the second ends are connected to a first cross beam of a skid, and a second set of the second ends are connected to a second cross beam of the skid. 
     
     
         11 . The drilling rig of  claim 10 , wherein the substructure further comprises one or more cross beams that transversely connect the first beam to the second beam, wherein the one or more cross beams are optionally removable and optionally adjustable in position along the skid. 
     
     
         12 . The drilling rig of  claim 1 , wherein the drilling rig has an approximate 500,000 pound setback capacity. 
     
     
         13 . The drilling rig of  claim 1 , wherein the substructure has a weight of approximately 135,000 pounds or less. 
     
     
         14 . The drilling rig of  claim 1 , wherein the top drive is reeved prior to and during transport of the drilling rig. 
     
     
         15 . The drilling rig of  claim 1 , wherein the mast comprises a telescoping mast having at least three sections comprising a bottom section, a top section, and one or more intermediate sections therebetween, wherein a variable line interconnects the bottom section to one of the one or more intermediate sections, and a fixed line connects a group of sections, wherein the group comprises at least one of the one or more intermediate sections and two more sections. 
     
     
         16 . The drilling rig of  claim 15 , wherein the one or more intermediate sections comprise a series of interconnected intermediate sections, wherein at least a bottommost intermediate section is connected to the bottom section and at least a topmost intermediate section is connected to the top section. 
     
     
         17 . The drilling rig of  claim 15 , wherein the variable line comprises a winch and winch line. 
     
     
         18 . The drilling rig of  claim 1 , wherein the mast comprises a telescoping mast having at least three sections comprising a bottom section, a top section, and one or more intermediate sections therebetween, wherein the telescoping mast comprises lines to simultaneously raise or lower heights of both the bottom section connected to one of the one or more intermediate sections, and the one or more intermediate sections connected directly or indirectly to the top section. 
     
     
         19 . The drilling rig of  claim 18 , wherein the lines comprise a first line that is variable and one or more fixed lines that interconnect the one or more intermediate sections to the top section. 
     
     
         20 . A method for assembling a drilling rig, the method comprising:
