On shore

Consists of raising and dropping a heavy metal bit into the ground, effectively punching a hole down through the earth. Cable tool drilling is usually used for shallow, low pressure formations. Many of these wells are now being drilled using a technique called pad drilling where multiple wells are drilled from the same site in very close proximity of each other by shifting the rig slightly. Typically, these are mature fields, pushing the drilling envelope farther to more challenging well formations like new shale fields or very deep wells.
