Abstract
A rig skidding method involving raising a rig on jacks, positioning skid tracks comprising low friction plastic underneath the rig, lowering the rig, and skidding the rig along the skid tracks to a new site for rig operations. At the new site, the process is reversed to leave the rig on the ground at the new location.
Claims19
A method of skidding a rig structure, the method comprising:
- raising the rig structure using jacks;
- after raising the rig structure, placing a skid track under the rig structure, wherein the skid track comprises a fracture resistant base layer, a low friction plastic sheet and a cooperating layer placed between the low friction plastic sheet and the rig structure, in which the low friction plastic sheet comprises a sheet of ultra-high-molecular-weight polyethylene;
- lowering the rig structure onto the skid track;
- and
- sliding the rig structure along the skid track.

A method of skidding a rig structure, the method comprising:
- raising the rig structure using jacks;
- after raising the rig structure, placing a skid track under the rig structure, wherein the skid track comprises a fracture resistant base layer, the fracture resistant base layer comprising plywood having at least a fracture resistance of ¾ inch cabinet grade fir plywood, a low friction plastic sheet and a cooperating layer placed between the low friction plastic sheet and the rig structure;
- lowering the rig structure onto the skid track;
- and
- sliding the rig structure along the skid track.

A method of skidding a rig structure comprising:
- placing beams in a position to support the rig structure;
- using jacks to raise the beams and rig structure;
- placing a skid track under the rig structure, wherein the skid track comprises a fracture resistant base layer, a sliding layer placed on top of the fracture resistant base layer and a cooperating layer placed between the sliding layer and rig structure;
- lowering the rig structure onto the skid track;
- removing the jacks and the beams;
- and
- sliding the rig structure along the skid track,
- wherein the skid track comprises a low friction plastic sheet.

A method of skidding a rig structure comprising:
- arranging jacks to be able to support the rig structure;
- raising the rig structure with the jacks;
- placing a skid track under the rig structure;
- lowering the rig structure onto the skid track with the jacks;
- removing the jacks;
- and
- sliding the rig structure along the skid track,
- wherein the skid track comprises a stainless steel metal sheet secured to move with the rig structure, a fracture resistant base and a low friction plastic sheet secured to the base between the stainless steel metal sheet and the base.
