Adjustable gauge stabilizers (AGS)
Adjustable gauge stabilizers (AGS), also known as ‘Variable Gauge Stabilizers (VGS)’ are designed to change the gauge or pad diameter of the stabilizer after tripping the string in the hole. These stabilizers can have two or three different gauge settings. Stabilizers are run in the hole in the closed position and pads can be opened to alter the stabilizer gauge hydraulically through pump pressure. Adjustable gauge stabilizers can be used with the motor as well as rotary drilling assemblies and provide greater inclination control.
