Abstract
An apparatus including a drilling tool for locating in a wellhead has fluid ports therein. The apparatus further includes a collar which is mateable with the drilling tool, such that the fluid ports in the drilling tool are blocked by the collar when the collar is mated with the drilling tool. The drilling tool can be a bit runnable drill string tool. The apparatus may also include a bit runnable wear bushing. The apparatus can advantageously be used to perform a method of testing a blowout preventer (BOP) on a subsea wellhead.
