A common drill rig used for "Shot Hole Drilling" is the L.I.S (Low Impact Seismic) mounted on track carrier for operation in cut lines or environmentally sensitive area. Truck mounted drill or 4X4 buggy are utilized in the prairies. These drill rigs use water or air to assist the drilling.

[pdf] Designed long-reach horizontal pad drilling applications for either shale gas or tight oil, walking rigs cut drilling costs by spending much more time making hole and much less moving (rig up and tear down), picking up and laying down drill strings and tools, and mixing different batches of drilling mud and cleaning mud tanks for drilling various wellbore sections.
