    In practice, this technique is mainly used for boreholes not exceeding 200 m in depth. When the borehole reaches a certain depth, it must be tubed regularly to balance the stresses supported by the rock at the borehole wall. This operation is called the casing of the well, and the steel pipe left in place is called the casing.
