What does the abbreviation PBTD stand for?

• A. Pressure Back To Depth
• B. Plugged Back Time Depth
• C. Plugged Back Total Depth
• D. Pore Back Through Depth

Answer: (C)

The operation described by this abbreviation is about sealing the wellbore at a deep point. Plugged Back Total Depth means a cement plug is set to isolate the interval down to the total depth of the well—the deepest point drilled. In drilling and completion work, a plugback is used to block off the lower part of the well while allowing access above it, which is essential for testing, re-entry planning, or abandonment. TD (Total Depth) is the standard reference for how deep the well has been drilled, so combining “plugged back” with “total depth” specifies exactly how far the plug extends. The other options don’t fit typical terminology: they pair depth with terms like pressure, time, or pore in ways that aren’t used to describe a plugback operation.
