Method and apparatus for movement of drilling equipment between adjacent drilling locations

A drilling pad adapter apparatus allowing a rig structure to be movable between at least two adjacent drilling locations on a drilling surface, said apparatus comprising:

• a. a drilling pad comprising a substantially planar rig support surface with at least one drilling location aperture passing therethrough;
• b. a rig base adapted for attachment to a bottom of the rig structure;
• wherein said pad can be placed on said drilling surface over the desired adjacent drilling locations such that each of said drilling locations coincides with a drilling location aperture,
• and wherein the rig structure comprises a surface-engaging tool and the rig structure can be attached to the rig base resting on said pad and positioned in a first position in alignment with a first drilling location aperture such that said surface-engaging tool can pass through said at least one drilling location aperture and access a first drilling location coinciding therewith;
• and wherein said rig structure attached to the rig base can be moved from said first position to a second position in alignment with a second drilling location aperture such that said surface-engaging tool can pass through a drilling location aperture and access a second drilling location coinciding therewith, by moving said rig structure attached to the rig base horizontally across said rig support surface from said first position to said second position.
