Milling Guidelines

Milling Guidelines

To effectively remove the cuttings while milling stuck pipe, it shall be ensured that:

- the yield point of the mud is increased as high as possible prior to commencing milling, taking advice from the fluids engineer.


- the flow is turbulent to prevent cuttings from blocking the annulus, (a minimum annular velocity of 115 ft/min is recommended at BOP’s riser)

Rotation shall start a minimum 1 ft above the fish. WOB and rpm shall be  adjusted to find the best milling rate while noting the rotating . . .
