A coil structure unit comprises a base and a tower structure, the tower structure comprises a plurality of intermediate units. The length of each of the plurality of intermediate sections can be about 50 feet. The length allows to utilize a manipulator that allows equipment such as lubricators and blowout preventers to be integral to the loads which will eliminate much of the rig up time and complication as well as having much more flexibility in operations to take the items on and off hole.

An electrically powered drilling rig, such as for slim hole drilling, includes a drilling floor positioned over a drilling well, a set of pieces of drilling equipment operable for drilling the well, a first enclosure being positioned remotely of the drilling well and at least one electric motor being housed within the first enclosure. The electric motor is operated to provide power to one or more of the set of pieces of drilling equipment. The electric motor is housed within the enclosure and is remote of the drilling well and provides a buffer therebetween to prevent sparks from reaching the drilling well, thereby decreasing a fire hazard. The electric motor may be powered by a mobile battery pack. The electric motor may power a hydraulic pump, which further provides hydraulic fluid under pressure to the pieces of drilling equipment.

A pipe racking system including two mechanical arms to move pipe stands to a dedicated position on a rig floor wherein at least one mechanical arm is connected to a mast of a drilling rig. A method to move a drilling rig comprising: providing a pipe racking system with two mechanical arms connected to the mast of the drilling rig; folding the pipe racking system onto the mast of the drilling rig; and transporting the drilling rig without disassembling the pipe racking system from the mast.
