A Novel Drilling Fluid for Underbalanced Drilling
Proceedings, 2009Interest in underbalanced drilling is growing worldwide. UBD, when properly designed, eliminates problems associated with the invasion of particulate matter into the formation. However, experience has indicated it is difficult to maintain a condition of continuous underbalance pressure throughout the complete drilling operation, resulting in fluid ...

Publisher Summary A drilling fluid, or mud, is any fluid that is used in a drilling operation in which that fluid is circulated or pumped from the surface, down the drill string, through the bit, and back to the surface via the annulus. The most critical function that a drilling fluid performs is to minimize the concentration of cuttings around the ...
