StingBlock Advanced Stabilization Conical Element Cutter Block

Overview Library

First unique-geometry cutter block with staged gauge pad which substantially increases tool stability

Engineered with a first-of-its-kind unique geometry, the StingBlock advanced stabilization conical element cutter block is specifically designed to improve footage and ROP in challenging drilling applications that pose a high risk of vibration to the BHA and impact damage to conventional cutter blocks. A staged gauge pad increases stability and the Stinger conical diamond elements are incorporated along the block for enhanced impact resistance. Field tests using this cutter block demonstrated up to a 29% increase in ROP and a 56% increase in footage as compared with benchmark results in the Gulf of Mexico.

Enhanced reamer stability, durability, and improved efficiency

In high-impact and challenging applications with hard and interbedded formations, the StingBlock cutter block provides significant stability due to its stage gauge pad in combination with Stinger elements incorporated along the pad. Stinger elements deliver a higher point load designed to fracture rock more efficiently than a conventional cutter. Additionally, the Stinger element helps disrupt the vibrations that can reduce the energy applied to drilling, thus lowering ROP.  All this means longer runs and longer life of the underreamer and BHA.
