ABSTRACT:
An embodied mobile drilling rig is made of three sections, two substructures and a mast section, which are easily transported and installed at a drilling site. Each substructure includes a mast starting section; a floor side box connected to the mast starting section; a subbase side box; elevating legs connected to the floor side box and the subbase side box; and a raising cylinder. The mast section connects to the mast starting sections. The raising cylinders engage the mast in order to raise the mast into a vertical orientation and then raise the floor side boxes into an operating position. The embodied mobile drilling rigs are configurable to be transported by road with as little as three major loads, all within legal or permitable load and dimensional limits for most regions.
