Abstract
A guide mat for a slant service or drill rig. The guide mat comprises rearward and forward portions and an open area in the rearward portion which is used to allow access to a wellhead. Adjustable pedestals are provided which move in orthogonal planes to the plane of the guide mat and thereby allow for convenient pinning of the mast of the rig to the mat such that the mast is maintained in its correct operating position while the drilling and/or service operations are underway.
