Conductor casing
Conductor casing is the first string set below the structural casing (i.e., drive pipe or marine conductor run to protect loose near-surface formations and to enable circulation of drilling fluid).
The conductor isolates unconsolidated formations and water sands and protects against shallow gas.
This is usually the string onto which the casing head is installed.
A diverter or a blowout prevention (BOP) stack may be installed onto this string.
When cemented, this string is typically cemented to the surface or to the mudline in offshore wells.
Onshore this is a short segment usually around 60 ft (20 m) long.
The conductor isolates unconsolidated formations and water sands and protects against shallow gas.
This is usually the string onto which the casing head is installed.
The conductor casing is always cemented to the surface.
It is the first and largest casing to be run.
It is generally set at 100 ft below the ground level.
The main function of setting the conductor pipe is sealing off the unconsolidated formations which are near the surface.
These formations can be easily washed out with continuous mud circulation; also they are characterized by low fracture gradient which can be exceeded by the hydrostatic pressure generated by the drilling fluids.
