Weatherford's drilling-with-casing (DwC™) system eliminates the need to trip pipe and bottomhole assemblies (BHAs), increasing drilling speed and reducing risk exposure by always having casing on or near the bottom. The DwC system simplifies well architecture by potentially reducing the surface casing size as well as contingency casing strings or liners. A casing string or liner can be eliminated by successfully drilling into or through a pressure transition or lost zone.

  • @BLUClan If you knew what these companies spent on lobbying and trying to avoid environmental law, you'd be stunned.

  • @chechnya if you were in the oilfield and knew the measures companies take to prevent that to happen you'd shit your pants, fyi your vehicle and other appliances are polluting the air around your house :)

  • Thanks for polluting the water, soil and air for a quick buck.
