Standpipe jumped 300 psi during a 2 a.m. connection on 12.4 ppg, so I isolated the 14‑P‑220, bled the bladder, and brought the backup online in under a minute to keep returns steady. I want a clean, repeatable sequence — anyone have a solid checklist or training doc for coordinating stroke cutback, discharge isolation, and driller choke/torque calls when the dampener goes soft or a liner bites it?
I’ve had similar issues at 2 a.m. too; it helps to have a quick reference for stroke cutbacks. Check out this training doc, it really streamlines calls when the dampener goes soft: https://www.oilrigtraining.com/checklist. Makes a huge difference.
You might want to run through your isolation checklist after you bring a backup online like the 14-P-220. A visual aid can help in stressful moments, especially at 2 a.m. when adrenaline’s high. I’ve found that having a laminated quick-reference card with key pressure numbers really speeds up the process.
