Pipe Ramp 

An angled ramp for dragging drill pipe up to the drilling platform or
.bringing pipe down off the drill platform

Pipe Rack

.A horizontal support for tubular goods


A hole in the rig floor 30 to 35 feet deep, lined with casing that projects above the floor. The
.kelly is placed in the rathole when hoisting operations are in progress


Wedge-shaped pieces of metal with teeth or other gripping elements that are used to prevent
pipe from slipping down into the hole or to hold pipe in place. Rotary slips fit around the drill
pipe and wedge against the master bushing to support the pipe. Power slips are pneumatically
or hydraulically actuated devices that allow the crew to dispense with the manual handling of
slips when making a connection. Packers and other down hole equipment are secured in
.position by slips that engage the pipe by action directed at the surface

A small enclosure on the rig floor used as an office for the driller or as a storehouse for small
.objects. Also, any small building used as an office or for storage


A set of clamps that grips a stand, or column, of casing, tubing, drill pipe, or sucker rods, so
.the stand can be raised or lowered into the hole

Spinning Chain

A relatively short length of chain attached to the tong pull chain on the manual tongs used to
make up drill pipe. The spinning chain is attached to the pull chain so that a crew member can
wrap  the  spinning  chain  several  times  around  the  tool  joint  box  of  a  joint  of  drill  pipe
suspended in the rotary table. After crew members stab the pin of another tool joint into the
box  end,  one  of  them  then  grasps  the  end  of  the  spinning  chain  and  with  a  rapid  upward
motion of the wrist "throws the spinning chain"—that is, causes it to unwrap from the box and
coil  upward  onto  the  body  of  the  joint  stabbed  into  the  box.  The  driller  then  actuates  the
makeup cathead to pull the chain off of the pipe body, which causes the pipe to spin and thus
.the pin threads to spin into the box
with my best wishes
