Casing While Drilling

Advantages

  • shorter well-construction time by eliminating extra trips, hole-gauging runs and separate casing runs;
  • reduced time factors — open-hole time;
  • minimized risk of the casing not reaching target depth;
  • minimized risk of casing sticking — loss of the BHA;
  • minimized risk of drilling-fluid losses;
  • improved wellbore-cleaning quality;
  • no need for standard BHAs — bits, reamers, drill collars, etc.;
  • effective well-control (kick) management.
