Flow Loop - CORRECT ANSWER-Mud tanks > Mud pumps > shock hose >
mud line > stand pipe > swivel > drill string > bit > annulus > flow line > shaker
> mud tanks
annular preventer - CORRECT ANSWER-Upper most portion of the BOP stack
It will close around and seal anything in the well bore, regardless of shape or size
Blind Rams - CORRECT ANSWER-Located below the annular preventer
Only activated when the drill string is out of the hole
When activated, two steel plates with a rubber seal come together to seal off the
well bore
Pipe Rams - CORRECT ANSWER-Located below the blind rams
Functions the same as the blind rams but has a cut out in the steel plate to
accommodate the size of drill pipe being used
,Sheer Rams - CORRECT ANSWER-Activated in emergency situations when the
well bore needs to be sealed off immediately
The shear rams cut the drill pipe off and seal the well bore
Accumulator - CORRECT ANSWER-Stores hydraulic fluid under pressure to
open and close the annular preventer, blind rams and pipe rams or the HCR valve
Must be stored a minimum of 23 meters away from the well bore
Hydraulically Controlled Remote Valve (HCR) - CORRECT ANSWER-Is the
flow valve that diverts flow or gas to the choke manifold
Choke Manifold - CORRECT ANSWER-Controls bottom hole pressure when a
kick or blow out occurs
It will divert flow back to the mud tanks or gas to the flare pit
Silicon Controlled Rectifier (SCR) - CORRECT ANSWER-The SCR converts AC
(alternating current) to DC (direct current)
The DC power is sent to the traction motors via cables to supply power to the
drawworks, mud pumps, or rotary table
Compound - CORRECT ANSWER-A series of chains and sprockets that
distribute power to the drawworks and/or the mud pumps
While drilling, engine#1 power will be sent to the drawworks for hoisting and
rotating, while engine#2 power is sent to the mud pumps

,When tripping in and out of the hole, both engines will be compounded to provide
the extra power to the drawworks for hoisting the drill string in and out of the
hole.
Differential Pressure - CORRECT ANSWER-Force of fluid per unit area as
compared inside and outside the drill string after the obstruction fluid experiences
when flowing through the bit nozzles; changes when bit is on and off bottom
EDR - CORRECT ANSWER-Electronic Drilling Recorder
An EDR screen is found on the rig floor, as well as in each of the shacks on the rig
location, and sometimes remotely in the client's office as well.
ROP - CORRECT ANSWER-Rate of drilling
Measured Depth - CORRECT ANSWER-Length of the wellbore as though
measured by a measuring tape. This length is tallied by the total length of pipe in
the hole when the bit is on bottom.
True Vertical Depth (TVD) - CORRECT ANSWER-The depth of the wellbore at
a given point, as measured by vertical displacement between the wellhead, and the
wellbore at a given point.
Vertical Section Direction (VSD): - CORRECT ANSWER-The azimuth of the
horizontal line drawn from a set point of the wellbore (Typically well center) to a
set target (Usually the final target at the end of the well).
, Vertical Section (VS): - CORRECT ANSWER-The horizontal distance drilled in
the vertical section direction.
Dogleg Severity (DLS): - CORRECT ANSWER-Measured in degrees per hundred
feet (or 30m), dogleg severity is a way of measuring kinks in the wellbore.
Consistent doglegs are needed when drilling the curve in order to build angle.
However, when attempting to drill a straight lateral, it is not good to have a sudden
severe dogleg. This creates problems transferring weight to the bit for the drilling
process, and also with running casing to the bottom of the wellbore.
Total Depth (TD): - CORRECT ANSWER-Refers to the total planned measured
depth of the wellbore. When total depth is hit, the well is complete. Everyone is
typically very happy at this point.
Driller - CORRECT ANSWER-This is different than the directional driller. The
Driller is the leader of the rig crew while on the rig floor, operates the heavy
machinery during the drilling process and while tripping. The directional service
company's Directional Driller will assist with drilling parameters while rotating
(drilling straight), and with the actual drilling process while sliding (steering
directionally)
Tool Pusher - CORRECT ANSWER-Head of the rig crew and in charge of
ensuring the rig's equipment is running.
