Abstract
In an optimized drilling-hydraulics program the variables are controlled in such a manner that the well can be completed safely, with minimum damage to borehole formation and at the lowest possible cost. To achieve this, fluid density should just slightly exceed the hydrostatic pressure in the formation being drilled in permeable zones. Therefore, safety considerations usually dictate the minimum fluid density that can be used. A minimum fluid density also helps to control sloughing shales which otherwise could lead to expensive reaming or fishing jobs.
