2. allow cuttings to settle out at surface

22
Q

What are the two classifications for Land Rigs?

A
  • Portable land rigs

- conventional land rigs

23
Q

What are the three classifications for offshore rigs?

A
  • Jack up rig
  • semisubmersible rig
  • barge
24
Q

What are the main components of a rotary drilling rig?

A
  1. Power system
  2. hoisting system
  3. fluid circulating system
  4. Rotary system
  5. well control system
  6. well monitoring system
25
Q

Engines used to deliver power to the rig use what kind of fuel and why is this fuel better than others?

A

Engines on the rig use diesel fuel because diesel is more environmentally friendly and burns cleaner than gasoline fuel

26
Q

Name two types of power systems available On the rigs?

A

Mechanical and electrical power systems are available on the rigs?

27
Q

Which rig power system is more efficient give two reasons?

A

Electrical power system is more efficient because it utilizes central power distribution system which supplies power to all the equipment on the wellsite while the mechanical system uses one engine for each piece of equipment.

28
Q

If required to drill inside a city, which power system would you choose and why?

A

Electrical system because it can plug in power from a transmission line directly and run the rig without having diesel engines. this would significantly reduce the noise coming from the rig

29
Q

What are the three principal components of the hoisting system?

A
  1. The derrick and substructure
  2. the block and tackle
  3. the drawworks
30
Q

What are the two routine drilling operations performed with the hoisting system?

A
  1. Making a connection

2. tripping pipe or making a trip

31
Q

What are the differences between a mast and a Derrick?

A

The mast is a portable Derek that a crew can raise and lower as a unit while a standard Derek is required to be assembled and disassembled piece by piece

32
Q

What is the drawworks used for?

A

Draworks are used for hoisting the drill string with the use of a drill line

33
Q

What parts does the drawworks consist of?

A

The drawworks consist of a revolving drum which the crew members wrap drill line around, it also contains chains and gear drive along with clutches so they driller can change speed and direction

34
Q

Name five components of the hoisting system?

A

The hoisting system consist of drawworks mast or Derrick, Crown block, traveling block and drilling line.

35
Q

What is the difference between a crown block any traveling block?

A

The crown block is stationary while traveling blocks move up and down the inside of the mast or Derrick.

36
Q

What are the major functions of the fluid circulating system?

A
  1. To remove rock cuttings from the hole as drilling progresses
  2. to transmit hydraulic horsepower to the bit
37
Q

What is the shale shaker?

A

A series of trays with sieves or screens that vibrate to remove cuttings from the circulating fluid

38
Q

What are the mud pits or mud tanks?

A

A series of open tanks made of steel through which the drilling mud is cycled to allow sand and sediment to settle out

39
Q

What are the mud pumps?

A

They are large reciprocating pumps used to circulate the mud on the drilling rig?

40
Q

What are the principal components of a circulating system?

A
  1. Mud pumps
  2. mud pits
  3. mud mixing equipment
  4. solid control equipment
  5. Drilling fluid
41
Q

What is the equation for pump horsepower?

A

Hp= PQ/1714

Where:
Hp= surface hydraulic horse power
P= pressure in psi
Q= flow rate in gpm (gallons per minute)

42
Q

Name the seven parts of a rotary system?

A
  1. Swivel
  2. Kelly
  3. Rotary Drive
  4. rotary table or turntable is used for top drive
  5. drive bushing
  6. Rotary hose
  7. drill string
43
Q

What is the monkey board?

A

A monkey board is a platform for which the derrickman works while making a trip. within the monkey board are a series of fingerboards which are used to hold the drillpipe as it is racked back while tripping

44
Q

What are the three options for rotating the drill bit?

A
  1. Kelly
  2. top Drive
  3. downhole mud motor
45
Q

What are the advantages to a top Drive?

A

The top Drive can pick one stand of drillpipe in one time versus a single by single for a Kelly.
it has the ability to backream which the Kelly does not

46
Q

Who is responsible for the entire platform on a platform offshore rig?

A

The offshore installation manager or OIM

47
Q

What is the job of the driller and the derrickman?

A

The job of the driller is to supervise the rig floor crew and be responsible for drilling the hole ; the Derekman is responsible for racking drillpipe stands in the Derrick and monitoring the properties of the mud

48
Q

If you are a new hire at the rig, what will be the name of the position that you will start with?

A

Floorhand or leasehand would be the first job to start with the rig

49
Q

Why do you need a barge captain on an offshore rig?

A

The barge captain is necessary for an offshore rig to ensure that the rig is stable for drilling in the sea and during rig moves

50
Q

Why is safety important?

A

Safety is important because staying safe means we will be able to do our jobs and return home without injury

51
Q

Who is responsibility is it to keep a person safe?

A

It is the responsibility of each individual to be safe and watch out for others

52
Q

If in an H2S environment what training should the person have?

A

In an H2S environment a person must have the necessary H2S training and be comfortable using breathing apparatus

53
Q

To work on an offshore rig what necessary training is required?

A

To work on an offshore rig you must have offshore helicopter safety training
