a0a502a091 Consider certain drilling fluids may cause the stator elastomers to swell. DIRECTIONAL DRILLING For directional drilling applications, Xcaliber recommends steerable systems which use stabilized ABH motors. The relationship between the rotor and the stator geometry determines the rotational speed and torque. By using a measurement while drilling (MWD) tool, a directional driller can steer the bit to the desired target zone. See also[edit]. References[edit]. This means that certain types of drilling fluids or additives may ruin the motor or lower its performance.
Most of PCPD pump failures are due to this elastomer part. External links[edit]. However, the operating conditions and environment should not degrade or induce mechanical failure of the elastomer part for the life of the equipment. Ng; G.W. Chunking where the rubber across the top of the stator has been worn away. Will allow circulation of the borehole regardless of the horsepower or torque produced by the motor. Ideally the kick off point should be selected in a non-abrasive homogenous formation.[2].
