Bits for rotary steerable systems

PH bits

Bits compatible with “Push-the-bit” RSS system have aggressive cutting structure and mean the radial displacement of whole assembly or its major part with respect to well axis.

The use of RSS changes the conventional drilling technology and allows effectively drilling long horizontal sections and wells with complex profile. Bits of this type are optimized specially for drilling with high ROP and are designed for specific system.

PT bits»

Bits compatible with “Point-the-bit” RSS system have long gage part and a set of depth-of-cut control elements on the blades that provide stable bit positioning by means of tilting drive shaft with respect to BHA or by means of changing its curvature.

Unique geometry of profile and cutting structure arrangement provide stable drilling without losing steerability and drilling with low torsional loads in intervals of rocks alteration.

By means of developed nozzles pattern bits allow effectively cleaning bottom-hole zone excluding secondary reworking of cuttings.
