Q

What API range is light oil?

A

> 31.1

29
Q

what API range is heavy oil?

A

<22.3

30
Q

what API range is medium oil?

A

31.3-22.3

31
Q

give 5 examples of PPE

A

coveralls, steel toe boots, safety glasses, hard hat, gloves, face shield

32
Q

what order to the 4 casings go?

A

conductor, surface, production, tubing

33
Q

what is fracking?

A

when water, sand and chemicals are sent down a well into the perfs at very high pressure, further opening the perfs and maximizing oil recovery

34
Q

what are the 2 types of rigs?

A

Kelly or Top Drive

35
Q

what are the different rig systems?

A

hoisting, circulating, rotating, and power

36
Q

what is the BOP

A

blowout preventer, it reduces/eliminates the risk of a blowout

37
Q

what are the common casing sizes?

A

4.5”, 5.5”, 7” (12m average length)

38
Q

what are 2 services that often complete wells

A

service rigs and coil tubing units

39
Q

briefly describe various components of a coil tubing unit

A

its injected into the well, hydraulically powered, run inside casing, used for completions and stimulations, quick, delivered on a reel, and hydraulically powered

40
Q

what are different features of a wireline unit?

A

braided cable, electric power downhole, similar to coil tubing except thinner wire

41
Q

what are packers used for?

A

isolating the producing formations from the rest of the well, run in on tubing and can be used in sour wells

42
Q

what is the primary function of the wellhead?

A

to seal off the reservoir from the atmosphere

43
Q

how does perforating work and what does it do?

A

a perf gun is lowered downhole on a wireline, an electric charge sets off the explosives set in the gun that blow right through the casing and cement, opening the formation so oil and gas can flow into it

44
Q

what are 2 common stimulations?

A

acidizing and hydraulic fracturing

45
Q

what are the 3 sectors of the oilfield?

A

upstream (exploration and production), midstream (transportation) and downstream (refining and marketing)

46
Q

what did the Native Americans originally use bitumen for?

A

waterproofing their canoes

47
Q

what year did Leduc #1 strike oil?

A

1947

48
Q

what major oilfield event happened in 1883?

A

gas was discovered by Medicine Hat while drilling for water

49
Q

what are different methods of exploration?

A

seismic, geologic mapping, and contour maps

50
Q

what is the selection criteria for a well? (many parts)

A

seismic support, geologic interpretation, economics at the time of drilling, and probability for success

51
Q

what are the 3 rig sizes and what do they mean?

A

single double and triple. they are based on how many stands of pipe the derrick can hold at one time

52
Q

what are 3 different rams found on a BOP

A

pipe, blind, and shear rams

53
Q

what is the mousehole used for?

A

holding the next pipe in

54
Q

what is the rathole for?

A

kelly pipe storage on the drill floor

55
Q

what is the spud date?

A

the date the bit hits the ground

56
Q

what are different casing tools?

A

scratcher, centralizer, casing head

57
Q

what are different types of artificial lift?

A

pumpjack, PCP, ESP, gas lift, and plunger lift

58
Q

what determines the pour point of oil?

A

the wax content

59
Q

the pour point is the ________ at which fluid ceases to flow: temp, pressure, humidity, density

A

temperature

60
Q

what are the 4 main types of separators?

A

horizontal, vertical, spherical, and cyclonic

61
Q

what is the main function of a separator?

A

to remove gas from liquid oil and water

62
Q

what is the main purpose of a heater treater?

A

to heat up emulsion to produce gas, clean oil, and water all separately

63
Q

what is gas sweetening?

A

a process that removes H2S from gas (amine)

64
Q

what is gas dehydration?

A

a process that removes water from gas (glycol)

65
Q

what is the main purpose of a compressor?

A

adds energy to gas by compressing it so it can be moved easier

66
Q

what are the 4 different pipelines (in order)

A

gathering, feeder, transmission, distribution

67
Q

what is a pig?

A

a pipeline inspection device, used to check for corrosion and various defects within a pipeline

68
Q

What is SAGD?

A

steam assisted gravity drainage. steam is injected into an oil producing reservoir above the production pipe. The steam softens up the oil, making it flowable so it can be pumped to the surface

69
Q

what are the 4 different disciplines for technologists?

A

geological, production, drilling and reservoir
