34
Q

done if the drawworks drum is full;
(1) the travelling block is lowered to the drillfloor; (2) the dead line anchor is unclamped, and (3) the line on the drawworks is unwound and discarded before the reserve line is threaded through the system onto the drawworks drum

A

Slip and cut operation

35
Q

A closed hydraulic circuit allowing the mud to flow from the surface to
the bottom of the hole, inside the drill string, and subsequently back to
the surface;

35
Q

Consists of mud pumps, distribution lines, and the mud cleaning and
accumulation system;

A

Circulating System

36
Q

Includes series of equipment for removing solids and gases from the
mud as it flows from the well back to the active pit before being
reinjected into the hole;

A

Circulating System

37
Q

Mud pumps supply the energy necessary for circulation.

A

Circulating System

38
Q

located at the start of the circulating system near the mud pumps
where drlling fluid is initially prepared, and maintained depending on
well bore conditions

Q

Preparation areas contains

A

Steel Mud Tanks/ Mud Pits

Bulk Mud Component Storage/ Mud House/ Sack Room

Bulk Tanks

Mud Mixing Hopper

Reserve Pit

41
Q

Eaxamples of Circuilationg Equipment

A

Mud Pump

Discharge Line

Standpipe

Rotary Hose/ Kelly Hose

Annulus

Mud Return Line/ Flow

42
Q

Station dedicated for decontaminating and conditioning drilling fluids
brought out of the well bore

A

Conditioning Area

43
Q

Conditioning equipment include:

A

Shale Shaker

Desander

Desilter

Degasser

44
Q

Any pit not part of the active (circulatory) system.

A

Reserve Mud Pit/ Mud Tank

45
Q

In operations on land, the reserve pit is usually a plastic-lined,
earthen pit, in which waste mud is stored until final disposal.

A

Reserve Mud Pit/ Mud Tank

45
Q

The reserve pit may be used to store spare or waste mud, base oil
or brine.

A

Reserve Mud Pit/ Mud Tank

46
Q

Powered by a centrifugal pump that
moves the mud at high velocity through a
venturi nozzle (jet) below the
conical-shaped hopper;

A

Mud Mixing Hopper/ Mud Hopper/ Jet
Hopper

47
Q

A mud-flow device for funneling materials
are put into the circulating mud system;

A

Mud Mixing Hopper/ Mud Hopper/ Jet
Hopper

48
Q

Dry materials are added through the mud
hopper to provide dispersion,
rapid hydration, and uniform mixing;

A

Mud Mixing Hopper/ Mud Hopper/ Jet
Hopper

49
Q

Liquids are sometimes fed into the mud
by a hose placed in the hopper.

A

Mud Mixing Hopper/ Mud Hopper/ Jet
Hopper

50
Q

a drilling mud filled open steel or
earthen berm tank that is not stirred
or circulated;

A

Settling Tank/ Settling Pit

51
Q

Somewhat cleans mud by letting it
pass slowly and allowing solids to
settle;

A

Settling Tank/ Settling Pit

52
Q

A major drawback to this type of
“cleaning” is that solids intentionally
put into the mud, such as barite,
may settle to the bottom and be
discarded rather than circulated
back into the wellbore.

A

Settling Tank/ Settling Pit

53
Q

A small pit, typically located
immediately after the shaker
screens, which is used as a settling
pit to separate coarser solids that
accidentally bypass the shakers;

A

Sand Trap

54
Q

Mud enters the pit at one side and
exits via an overflow at the other;

A

Sand Trap

55
Q

They are dumped periodically to
remove the settled solids, or
alternatively the contents can be
processed over a fine screen or with
a centrifuge.

A

Sand Trap

56
Q

Small compartment, normally
adjacent to the suction
compartment, used to mix
special fluids to pump downhole;

A

Slug Tank

57
Q

Most commonly used to prepare
a small volume of weighted
drilling fluid before a drillstem trip
in and out of the borehole.

A

Slug Tank

58
Q

Used for mixing special
chemicals like caustic soda
(sodium hydroxide) before it is
placed in the active mud tank

A

Chemical Tank

59
Q

Positive displacement type
pumps are used (reciprocating
pistons) to deliver the high
volumes and high pressures
required to circulate mud through
the drillstring and up the annulus;

A

Mud Pumps

60
Q

Duplex (2 cylinders) -

A

double acting

61
Q

Triplex (3 cylinders) -

A

single acting

62
Q

At least TWO pumps are
installed on the rig;

A

Mud Pumps

63
Q

At shallow depths they are
usually connected in parallel to
deliver high flow rates;

A

Mud Pumps

64
Q

Single-acting pumps (i.e., Triplex
pump) discharge on either the
forward or return stroke of the
piston or plunger; every cycle of
the pump displaces only one
volume of liquid.

A

Single acting

65
Q

As the well goes deeper the
pumps may act in series to
provide high pressure and
lower flowrates.

A

Mud Pumps

66
Q

In double-acting pumps (i.e.,
Duplex pumps), liquid is
discharged on both the forward
and return stroke of the piston.

A

double acting

67
Q

are generally used
in offshore rigs and duplex pumps
on land rigs;

A

Triplex pumps

67
Q

are only
single-acting; can be
either single- or double-acting.

A

Plunger pumps
Piston Pumps

68
Q

have two cylinders
and are double-acting (i.e. pump
on the up-stroke and the
down-stroke).

A

Duplex pumps

69
Q

A positive-displacement reciprocating pump that is configured with three plungers;

A

Triplex Pumps

70
Q

The most common configuration of
pump used in both drilling and well
service operations;

A

Triplex Pumps

71
Q

Capable of handling a wide range
of fluid types, including corrosive
fluids, abrasive fluids
and slurries containing relatively
large particulates.

A

Triplex Pumps

72
Q

Commonly used on workover rigs,
that has two plungers or pistons;

A

Duplex Pumps

73
Q

As a positive-reciprocating pump,
the fluid flow rate is typically
calculated from the number of
strokes per minute that the pump
makes and the displacement
volume per stroke;

A

Duplex Pumps

74
Q

Such a level of accuracy usually is
sufficient for general workover
purposes.

A

Duplex Pumps

75
Q

Line connecting the pump to a
series of tubulars and equipment
to feed drilling fluids into the
