A drilling rig is a machine which creates holes (usually called boreholes) and/or shafts in the ground. A drilling rig is a machine that creates holes in the earth sub-surface. Drilling is an operation of making a circular hole by removing a volume of metal from the job by cutting tool called drill. For most offshore wells, the type of rig required will fall into one of three groups: Jack-ups, where the water depth is less than 100 m. When drilling this deep, the speed and feed rate must be adjusted to reduce friction. Our supply of drilling rigs, drilling rig components, drilling rig packages, drilling equipment, and top drives meet the industry standards established by the American Petroleum Institute (API).
