Connection types

Casing connections should satisfy several functional and operational requirements which are presented in this article.

Functional aspects

  • to provide a leak resistance to internal or external fluid pressures
  • to have sufficient structural rigidity to transmit externally applied loads
  • to have good geometry in order not to increase the outer diameter or reduce the inner diameter of the casing string significantly

Operational aspects

  • easy to make-up in the field
  • easy to break-out in the field
  • reusable

To fulfil . . .
