Differential Sticking Tester / Mud Sticking Tester

Measures the Stuck Tendency Coefficient with the Timed Filtrate Test.

Working Pressure: 477.5 psig (3,291 kPa).

Working Temperature: up to 170℃ (340℉)

Differential sticking may be identified by the following characteristics:

1. Pipe sticks after remaining motionless for a period of time

2. Pipe cannot be rotated or moved when circulation is maintained

The standard test uses 477.5 psig (3292 kPa) differential pressure applied to a stainless steel vessel of approximately 200 ml capacity. The measurement can be made using either the flat-faced torque plate or the 12-1/2" (31.75 cm) spherical radius plate which approximates pipe in casing or collars in borehole contact geometry. (Both are provided.) In the event of a "sticky" sample that tends to adhere more to the torque plate than to the filter paper, stainless steel micro-corrugation disks are provided, to help ensure success of the test.
