Drilling Problems Related to Drilling Fluids
This chapter covers those drilling fluids issues that can cause delays in drilling the well. These issues can be very expensive and need to be eliminated or remediated as quickly as possible. These problems include stuck pipe, wellbore instability, slow drilling rates, excess torque and drag, lost circulation, high temperature additive degradation, and corrosion.

In oil well drilling, various problems related to drilling fluid properties arise. Some of these problems, such as slow drilling rate or excessive drill pipe torque, merely render the ...
