Drilling with Casing

Increase efficiency and mitigate drilling hazards with simultaneous drilling and casing

Simultaneous drilling and casing operations accelerate well construction, reduce risk exposure, and mitigate potential hazards. Using our drilling-with-casing (DwC) or drilling-with-liner (DwL) systems, you can drill, ream, run, set, and cement your casing or liners in a single trip. Our DwC systems are compatible with our OverDrive casing-running and drilling system for added benefits.

Drill Bits

Drill in any environment to the planned depth

With polycrystalline-diamond-compact performance at temperatures up to 400°F (204°C), our Defyer® drillable casing bits enable you to drill and case across soft, medium, and hard formations.

Retrievable Drilling With Casing

Recover your BHA before and after reaching total depth

Our retrievable drilling-with-casing system enables to retrieve your bottomhole assembly (BHA) to replace damaged or worn components or to recover advanced systems—without pulling the entire casing string.

 

Drill, case, and recover your BHA from directional wells
