Abstract
The method includes providing a wellhead comprising a first casing spool and an extended tubing spool disposed above the first casing spool, and a production tree comprising a wing valve disposed above the extended tubing spool. The method further includes decoupling the extended tubing spool from the wellhead, coupling a replacement tubing spool and an additional casing spool below the replacement tubing spool to the wellhead replacing the extended tubing spool. A combined length of the replacement tubing spool and the additional casing spool is the same as the length of the extended tubing spool. The method further includes maintaining a consistent vertical length between the first casing spool and the wing valve while replacing the extended tubing spool with the replacement tubing spool and the additional casing spool.
