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.

Abstract: A method for installing a mobile drilling rig at a drilling site entails transporting the mobile drilling rig to the drilling site, wherein the mobile drilling rig is made three sections: two substructures and a mast section. The substructures are placed parallel to one another at the drilling site. The mast section is connected to the mast starting sections located on each substructure. Raising cylinders on the substructures engage the mast and raise the mast into a substantially vertical orientation, wherein the mast is locked in place. The raising cylinders are retraced and then re-extended into a drillfloor raising position. The method ends by extending the raising cylinders to raise the driller's floor side box and the off-driller's floor side box into an operating elevation.
