PETE 1010 – Exam 2 Study Guide (Petroleum Engineering Review, Key Concepts & Practice
Questions with Answers)
tool pusher - ✔✔contractors top manager on drill site, responsible for rigs overall operation
and performance. Makes sure crew drills well to operators specifications (aka rig superintendent
or rig manager)
driller - ✔✔subordinate only to tool pusher, operates drilling machinery, manages day to day
activities of the derrick hand and rotary helpers
derrick hand - ✔✔looks after the mud pumps and sometimes monitors and records the
conditions of mud, they handle the pipe from a platform on top of the derrick
rotary helpers - ✔✔handle the bottom of the pipe on the rig floor when pipe is removed from
or put into the hole (aka floorhands or roughnecks)
roustabouts - ✔✔assist in loading and unloading equipment and supplies delivered by boat to
the rig, on land rigs they're called lease hands
company representative - ✔✔representative representative of the operator on the drilling
location. Responsible for issues on location such as safety and efficiency
contract - ✔✔agreement between the operator and the contractor that spells out what each is
expected to do and provide to drill the well to specifications
footage contract - ✔✔operator agrees to pay the contractor a certain amount for each foot
drilled. Riskier for the contractor because the operator pays the contractor certain amount
regardless of the time it takes
, daywork contract - ✔✔most common, operator pays the contractor an amount per day to use
the rig, regardless of how much work the rig is performing, paid by hour not by foot
turnkey contract - ✔✔requires the operator to pay the drilling contractor an agreed amount
when the well is finished. The contractor will furnish all equipment, materials, and people
needed to drill, operator assumes all financial risk
combination agreement - ✔✔combines payment agreements. Ex: paid by footage to a certain
depth and then by day rate below that depth
hoisting system - ✔✔hoists drill pipe in and out of hole, support drill and keeps it in tension,
consists of: derrick (posts), draw-works (spool and crank), drilling line (rope), crown block (fixed
atop derrick/mast), traveling block (moves up and down)
derrick - ✔✔permanent A-frame structure with legs that sit on the corners of the rig floor
crown block - ✔✔sits atop the derrick and never moves
traveling block - ✔✔moves up and down the center of the derrick, lifts and lowers drill strings
drilling line - ✔✔made of wound steel wire, runs from supply reel to crown block through
sheaves, goes down to traveling blocks and wraps around sheaves, weaves several times to
increase strength, anchored at draw works drum
draw works - ✔✔one of the largest and heaviest equipment on a drilling rig. houses the drum
which drilling line is wrapped
rotating system - ✔✔includes all the equipment that turns the bit. consists of: swivel, kelly,
rotary table, top drive, drill pipe, drill collars and bit
