Features

The Sting diamond element bit leverages the unique 3D geometry of Stinger diamond elements for superior impact and wear resistance. Sting bits improve ROP and footage drilled while maintaining greater tool-face control and minimizing shock in challenging drilling applications that can cause impact damage to conventional bits.During field testing in over 27 wells, Sting bits averaged 47% increase in footage compared with offsets.Element placement mitigates several causes of damage. In addition to the increased impact resistance enabled by Stinger elements, Sting bits drill with less overall torque than PDC bits, reducing reactive torque fluctuations. This allows Sting bits to yield higher build rates, to stay on target better, and to achieve directional drilling objectives in less time. With a more balanced cutting response, Sting bits consistently drill with less shock and vibration, enabling longer runs at higher ROP, prolonging the life of the bit and other BHA components.

Positioning Stinger cutters across the bit face delivers a step change in drilling performance and rock failure.Composed of high quality polycrystalline diamond materials and built into a unique conical shape, Stinger elements dissipate heat more efficiently than conventional PDC cutters for improved wear resistance. 

The FEA software for the cutters distribution and layout made the  drilling more efficient and reduce NPT.

Optimize the angle of the cutter in both axial and radial by FBS(force balance analyze) software resulting in stronger aggressive and more durability of the bit.

DOC(depth of cutters) was calculated and optimized by a series experiences of the bit,made the cutter penetrate the formations more rationally.
