DRILLING FLUID PROPERTIES & FUNCTIONS
DRILLING FLUID PROPERTIES & FUNCTIONS

4/6/2010, · ii. In clay and shale ,drilling,, it is most important to seal off this formation and to reduce hydration of the formation. Bentonite clay ,drilling mud, cannot perform this ,function, alone. Adding small amounts ,of polymer, to the bentonite clay ,mud, or switching to an all ,polymer drilling fluid, system will offset this problem.

Gaseous ,Drilling Mud, Systems. This system involves injecting air or gas downhole at the rates sufficient to attain an annular velocity of 2,000 to 3,000 ft/min. Hard formations that are relatively free from water are most desirable for ,drilling, with air-gas ,drilling, fluids. Small quantities of water usually can be dried up or sealed off by various techniques.
