Which device is ran on the inside of tubular goods to ensure that the pipe has the proper drift?

• A. Drift Meter
• B. Rabbit
• C. BOP
• D. Packer

Answer: (B)

Verifying the bore size inside tubulars is done by running a calibrated mandrel through the inside to prove there are no obstructions and that the interior diameter is within spec. This pass-through tool is commonly called a drift, and in many field contexts it’s referred to as a rabbit. By pulling the rabbit through the pipe, you confirm the tube can accommodate the required tools and threading without getting hung up. The other items aren’t used for this purpose: a BOP is a surface well-control device, and a packer seals zones downhole; a drift meter measures diameter but the actual device run through the bore to check drift is the rabbit.
