PDC BIT STEERABILITY MODELING AND TESTING FOR PUSH-THE-BIT AND POINT-THE-BIT RSS

The footage drilled with rotary steerable systems (RSS) has increased significantly these last few years, due notably to the highly complex wells drilled today. Moreover, high requirements about borehole quality are needed to optimize drilling performances, running completion tools or increase the quality of formation evaluation. Rotary steerable systems can be classified in two types according to the steering mechanism: point-the-bit and push-the-bit.Whatever the type of steering mechanism, both tilt and side force are applied on the bit. Although bit tilt is predominant in point-the-bit system, bit side force is the main factor that affects hole deviation in push-the-bit system. There have been many controversies in the scientific and industrial community regarding the deviation mechanisms involved in these two systems.

To react to this controversy, a full-scale drilling bench has been developed to test drill bits in push-the-bit, point-the-bit or hybrid push-point mode. This new facility enables to apply any coupled tilt-side force on the bit to reproduce the RSS mechanisms.

To react to this controversy, a full-scale drilling bench has been developed to test drill bits in push-the-bit, point-the-bit or hybrid push-point mode. Interesting, right?
