Shaped-Cutter Line

Halliburton introduced Geometrix 4D Shaped Cutters, a line of four distinct geometric profiles to help improve cutting efficiency and increase control to reduce drilling costs. Geometrix cutters expand the capabilities of traditional polycrystalline diamond materials by shaping the cutting structure to optimize drilling performance for specific applications. Traditional flat cutters generate heat and wear, which slow drilling progress because operators must frequently check or replace damaged bits. The new line includes the Chisel Plowed Scribe Cutter for brittle formations such as carbonates, the Chopper Plowed Cylinder Cutter for increased heat dissipation in high-energy drilling operations such as shale formations, the Dagger Multi-Plowed Cutter with fluid channels to improve cleaning and prevent plugging around the cutter face, and the Machete Optimized Tip Geometry Cutter for use in formations that require high point loading. In a recent offshore job in Mexico where an operator was drilling a limestone/shale formation, the Geometrix bit doubled the rate of penetration over a 700-m section, saving the ­operator 3 days of drilling time compared with offset wells.
