What is the purpose of a kill sheet in well control?

• A. Documents the step-by-step kill procedure, required mud density, volumes, pump rates, pressures, and action sequence to safely kill an inflowing well
• B. Contains the marketing information
• C. Logs only the last 24 hours
• D. Specifies weather conditions

Answer: (A)

In well control, a kill sheet is the plan and record for how to shut in an inflowing well safely. It lays out the step-by-step kill procedure and notes the required mud density (the kill mud), the volumes to be pumped, pump rates, target pressures, and the exact action sequence the crew will follow. This keeps everyone on the same page, reduces the risk of missing a step, and lets the team track progress as the operation unfolds. It also provides a documented trail for review after the event. The kill sheet is not about marketing, it isn’t just a log of the last 24 hours, and it doesn’t specify weather conditions; its purpose is to guide and document the controlled kill of the well by balancing formation pressure with the right mud properties and pumping actions.
