PETE 225: Introduction Exam Overview
Crown Blocks - correct answer ✔✔A set of stationary pulleys or sheaves at the top of the derrick. Part of
the hoisting system. There is a wire rope (a.k.a drilling line) strung between the travelling blocks and
crown blocks that through a tremendous mechanical advantage allows the weight of drill string, drill
stem or casing string to be supported and moved by the rig.
V-door - correct answer ✔✔The opening in the railings at the top of the slide (a.k.a. Beaver slide).
Components are brought from the catwalk, up the beaver slide and through the v-door to the rig floor.
Tongs - correct answer ✔✔There are several types, each sized for what drillstring or casing component
they are meant for. Tongs can be powered (typically hydraulically) or mechanical (using the make-up and
break out lines). They are used make-up (put together) or break out (take apart) drillstring, BHA, and
casing by rotating or spinning one of the components being made-up or broken out.
Mousehole - correct answer ✔✔The hole in the rig floor between the rotary table and v‐door. It is
typically drilled then cased with steel liner
similar to casing. During drilling operations the next joint or stand of drillpipe or hevi ‐wate drillpipe will
be placed here and
made‐up (if a stand) prior to being picked up and made ‐up onto the drillstring.
BHA - correct answer ✔✔Bottom-hole assembly
Monkeyboard - correct answer ✔✔is where the derrickman stands while tripping pipe. It is located at
the same height of 2/3 of a stand of pipe.
The monkeyboard has racking fingers on it that divide each side of the board area into a series of slots.
Pipe is racked into
these slots as it is pulled out of the hole. This way it can be quickly run back into the hole as opposed to
breaking each stand
into 2 or 3 individual joints each time a trip is made.
Pipe racks - correct answer ✔✔are steel frames (typically an A-frame) that hold the
casing/tubing/drillstring/BHA in storage or on the rigsite.
Crown Blocks - correct answer ✔✔A set of stationary pulleys or sheaves at the top of the derrick. Part of
the hoisting system. There is a wire rope (a.k.a drilling line) strung between the travelling blocks and
crown blocks that through a tremendous mechanical advantage allows the weight of drill string, drill
