Claim Text:
1. A mobile rig for low wind resistance for engaging and disengaging joints of a conduit to and from a conduit string, lowering and raising the conduit string into and from a well, and performing completion operations on the well, the mobile rig comprising: a mobile rig carrier; a mast assembly connected to the mobile rig carrier, wherein the mast assembly extends vertically directly above the well, wherein a lower surface of the mast assembly contacts an upper surface of the well, wherein the mast assembly has a width measured perpendicularly from the longitudinal axis of the mobile rig, and wherein the mast assembly is resistant to a dynamic wind force; and a pipe handling system positioned proximate to the mast assembly for moving pipe into and from engagement with a drive system disposed on the mast assembly, wherein the pipe handling system is connected to the mast assembly, wherein the pipe handling system is positioned on an opposite side of the well with respect to the mobile rig carrier, and wherein a lower surface of the pipe handling system directly contacts the upper surface of the well; a pair of base beams for providing stability thereto, wherein the pair of base beams extend from the mast assembly, mobile rig carrier, or combinations thereof, wherein each base beam comprises one or more flat mats, and wherein the pair of base beams comprise two or more flat mats having a combined width at least as wide as the mast assembly, wherein the combined width of the mats is measured perpendicularly to the longitudinal axis of the mobile rig and wherein the flat mats of the pair of base beams are hydraulically deployed, and wherein the one or more flat mats rest substantially flat on a surface adjacent to the wellbore when deployed.
