Method and apparatus for movement of drilling equipment between adjacent locations
First Claim
1. A drilling apparatus capable of drilling in at least two drilling locations on a drilling surface, said drilling apparatus comprising:
- a. a rig structure including a surface-engaging tool, said rig structure having a rig base with a substantially planar lower surface;
b. a drilling pad having a substantially planar rig support surface with at least one drilling location aperture passing therethrough, wherein said pad can be placed on the drilling surface over desired adjacent drilling locations such that each of said drilling locations coincides with a drilling location aperture, and wherein the lower surface of the rig base rests on said rig support surface;
wherein said rig structure can be positioned on said pad in a first position in alignment with a first drilling location aperture such that said surface-engaging tool can pass through said first drilling location aperture and access a first drilling location coinciding therewith;
and wherein said rig base can freely slide fore and aft and left and right and diagonally over the rig support surface of said pad, such that the rig structure 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 said second drilling location aperture and access a second drilling location coinciding therewith by sliding said rig base horizontally fore and aft and left and right and diagonally as required across said rig support surface from said first position to said second position.

Abstract
An apparatus and method for the movement of drilling equipment between topographically adjacent drilling locations comprises positioning a transportable planar surface over the adjacent drilling locations between which it is desired to move the equipment. Ports or other access areas extending through the planar surface to the drilling locations below are provided. The equipment to be moved is placed on top of the planar surface and is provided on its bottom with a low-drag surface which can slide across the planar surface. The equipment can be moved from one desired drilling location to another by sliding it between locations on top of the planar surface. When all of the drilling is completed, the equipment can be struck for transport and the planar surface disassembled and moved to a new drilling area. Various methods to move the equipment could be used.

29. 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 and having a substantially planar lower surface; 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 with the lower surface of the rig base resting on said pad and positioned in a first position in alignment with a first adjacent 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 freely slide fore and aft and left and right and diagonally over the rig support surface of said pad, such that the rig structure can be moved from said first position to a second position in alignment with a second adjacent 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 sliding the rig base horizontally fore and aft and left and right and diagonally as required across said rig support surface from said first position to said second position. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36)

37. A method of moving a rig structure on a drilling surface between adjacent drilling locations, said method comprising the steps of:
-
a. providing a drilling pad having a substantially planar rig support surface with a plurality of drilling location apertures passing therethrough, wherein said drilling pad is placed on said drilling surface over desired adjacent drilling locations such that each of the desired drilling locations coincides with a drilling location aperture; b. placing a substantially planar lower surface of a rig structure on said rig support surface, said rig structure including a surface-engaging tool; c. sliding said rig structure horizontally fore and aft and right and left and diagonally as required across said rig support surface as required until said rig structure is aligned with a selected drilling location aperture coinciding with a desired drilling location such that the surface-engaging tool can access the desired drilling location through said selected drilling location aperture. - View Dependent Claims (38, 39)
