A method for drilling through a producing zone in a subterranean formation or for completing a wellbore in a subterranean formation, using a drill-in and completion fluid comprising a blend of a phosphate brine and water. Undesirable conditions, such as a degrading cold head, plumbing leaks, and so forth, may be detected earlier by monitoring heater duty cycle. A manually-operated plunger mechanism then removes the candies from the magazine. This invention uses two bearings and quick release axle to connect the front and rear frame together and provide the steering axis.
