A fluid formulation was developed that was based on using the high shear rate of the drill bit to thicken the fluid irreversibly. This allows the fluid to be controlled for application to specific wellbore problems. This fluid was field tested in 10 different wells that had severe drilling problems. It was used successfully in a majority of those cases. In instances when it failed, the only method that worked was to set casing. Since testing this fluid, we have developed an improved formula that is easier to pump and has higher initial strength. This improved formula now has been field tested.
