Shutting and killing a well in phases
Shutting and killing a well in phases
(OP)
Hi,
I don't understand how a well is shutted and killed. What is the "kill phase" diagram and can anyone explain to me?.
Any information lecture notes, graphs,material attached are appreciated.
Thanks

Its about a producing well. If for instance a well has to be shutted due to e.g maintenance operations in the wellhead or failure downhole how the shutting and killing process will take place. I understand that a heavy mud is used.

You wouldn't used mud to kill a well you want to bring back on, as you will proabaly have problems getting the well to flow again- you'd use the various solids-free brines that are available at variuos weights up to 16ppg: NaCl, bromides, formates, whatever, with a pill to stop the brines flowing away into the reservoir.
If you're killing the well before plugging & abandoning it, you'd use mud, probably the mud you've been using to drill the well.
