Gas-lift well

Gas-lift well

Casing designs for wells in which gas-lift completions are to be installed are based upon different design load cases from standard wells. They have to be treated differently from standard wells in two respects:

  1. definition of the possible pressure profiles within the "live" tubing/production casing annulus (A-annulus)
  2. design of the intermediate casing to withstand the consequences of a leak in the production casing for subsea wells.

A-annulus pressure profiles for the production phase should be constructed, in close cooperation with the Production Technologist, for . . .
