The new Spear shale-optimized steel-body PDC drill bit saved significant rig time in the Haynesville Play. Key features include tall, thin blades with optimized mud nozzle configuration for extra cooling potential and prevention of cuttings re-grinding. An extra-large junk slot area allows efficient cuttings removal. The bit is optimized for drilling both the build section and lateral section of horizontal boreholes. A record run in Louisiana’s Haynesville play saved one operator $365,495 in rig-time because of improved penetration rate and elimination of bit runs.
