Methods and apparatuses associated with a rotary driven well drilling rig. One method includes providing a rig having: an erectable mast; a head drive unit for rotatably driving drill pipes into a surface; a pumping unit to deliver a fluid through a drill pipe secured to the head drive, the fluid being forced out a bottom end of the drill pipe and up to the surface along the outside of the drill pipe during a borehole drilling operation; and a deck unit pivotally mounted on a turret attached to a set of tracks. This method embodiment includes, while the rig is in a first location, performing a first borehole drilling operation to form a first borehole at a second location; and performing a second borehole drilling operation to form a second borehole at a third location while the rig remains in the first location.
