Steel Solutions in Borehole Drilling

The Mild Steel Casing, also known as a setting pipe, is a large-diameter steel pipe assembled and inserted into a recently drilled section of a borehole to protect and support the good stream. It is similar to the bones of a spine protecting the spinal cord.

The purpose of the Mild Steel Casing in borehole drilling is to:

✔ Prevent Buckling of casing in deeper boreholes

✔ Prevent contamination of fresh water well zones.

✔ Prevent unstable upper formations from caving in and sticking the drill string or forming large caverns.

✔ Provide a strong upper foundation to use high-density drilling fluid to continue drilling deeper.

✔ Isolate different zones (that may have different pressures or fluids known as zonal isolation) in the drilled formations from one another.

✔ Seal off high pressure zones from surface, avoiding potential for a blowout.

✔ Prevent fluid loss into or contamination of production zones.

✔ Provide a smooth internal bore for installing production equipment.
