A conventional land drilling rig is interconnected to the substructure for an oilfield pad location. The interconnected drilling rig is placed on top of matting. The matting has embedded rollers to facilitate movement of the drilling rig as a “convoy” across the mat from one wellhead to another wellhead. The buildings in the mud tank system may also be interconnected and move in a separate convoy but in tandem with the first convoy.
