23
Q

attached to the traveling block and supports the load

A

drilling hook

24
Q

Rotating systems used to rotate the drillbit

A
  1. conventional rotating system
  2. power swivel
  3. down-hole mud motor
25
Q

the rotary table spins the kelly bushing, whose flat-sided hole matches the flat sides of the kelly. this rotates the drillstring and bit.

A

conventional rotating system

26
Q

relatively new. uses hydraulic motor integrated into the swivel to transmit rotary power. this replaces the kelly, kelly bushing and rotary table.

A

power swivel

27
Q

used for directional drilling. it turns the bit without rotation of the drillstring.

A

down-hole mud motor

28
Q

drilling fluids

A

mud

29
Q

most common used mud

A

saltwater with additives

30
Q

mud engineers

A

monitor the mud’s characteristics

31
Q

pipe handling

A
  1. elevators
  2. Slips
  3. Tongs
  4. fingerboard
  5. rathole
  6. mousehole
32
Q

attached to the hook are used to lift the pipe string

A

elevators

33
Q

used to hang the string from the rig floor

A

slips

34
Q

used to make-up and break-up the pipe joints

A

tongs

35
Q

in the derrick has protruding fingers that hold stacked stands on pipe in place.

A

fingerboard

36
Q

a hole in the rig floor where the kelly and swivel are stored when not in use

A

rathole

37
Q

a hole in the rig floor where a joint of pipe is place prior to being added to the string

A

mousehole

38
Q

The source of power for the entire rig.

A

prime mover

39
Q

most of the rig’s time is occupied by _______ also called “turning to the right” or “making the hole”

A

Drilling Ahead

40
Q
  1. Drilling ahead
  2. Making a connection
  3. Round tripping
  4. Automated rigs
A

Routine Drilling Procedures

41
Q

attaching a new joint

A

making a connection

42
Q

When you come out of the hole with the drillstring to change the bit, add drill collars, etc.

A

Round tripping

43
Q

Rigs using robots

A

automated rigs

44
Q

prevents hole from collapsing

A

surface casing

45
Q

normally a few hundred feet deep. Large diameter casing is run to the bottom, cement slurry pumped down and up the “backside” annular space between the casing and the hole

A

surface casing

46
Q

A safety valve at the top of the hole just underneath the rig floor. when activated it closes and seals off the well.

A

Blow out Preventer (BOP)

47
Q

the most common cause of stuck pipe.
