Best practices to mitigate corrosion in drilling and completion operations

Mitigation in drilling operations

While tripping:

  • Use a wiper rubber while tripping out of hole.
  • Keep the racking area clean (free of well fluid and solids).
  • Apply thread compound to connections.

When laying pipe down:

  • Clean the inside and outside of pipe.
  • Clean thread protectors before putting them back on connections.
  • Clean and dope connections before putting thread protectors back on.

Corrosion rings can be used with API connections seating in the box tapered section. Double-shouldered connections leave no space for corrosion rings to seat on. A special tool (double sub) needs to be built to hold the ring.

Mitigation in completion operations

While tripping the completion string:

  • Use a wiper rubber while tripping out of hole.
  • Wash the pipe on every trip out.
  • Clean, dry, and dope pins and boxes before racking.
  • Use a rubber racking mat to prevent accumulation of completion fluid around pins.

A sufficient amount of dope should be applied when running completion. Completion fluids are generally more corrosive than drilling fluids.
