1
Q

makes up the bulk of the drill string. the tool joint is larger in diameter (upset) than is the shank of the joint.

A

Drill pipe

2
Q

Thick walled joints of drill pipe used to put weight on the bit. The tool joints are of the same diameter (not upset) as the shanks of collars.

A

Drill collars

3
Q

The top most joint of drill pipe in the drillstring. It has flattened sides (4 to 6) used to transfer torque from the rotary system.

A

kelly

4
Q

the heaviest work on a drilling rig is performed by the

A

Hoisting system

5
Q

This is tall enough to pull triples ( a three joint “stand” of drill pipe) and strong enough to bear the weight of the entire drillstring.

A

Derrick

6
Q

steel wire rope

A

drilling line

7
Q

a large rotating drum that spools in drilling line to raise the load or spools out line to lower the load.

A

drawworks

8
Q

mounted in the top of the derrick and the traveling block connected to it by the drilling string

A

crown block

9
Q

attached to the traveling bock and supports the load

A

Drilling hook

10
Q

used with most onshore wells and many offshore wells. the kelly joint, with the rest of the drillstring suspended below it, passes through the kelly bushing attaches to the swivel hanging from the drilling hook. 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

11
Q

top drive. uses a hydraulic motor integrated into the swivel to transmit the rotary power. Have the advantages of permitting circulation and rotation while pulling out of the hole and adding a full stand pipe (3 joints) rather than only one joint at a time as the hole deepens.

A

Power swivel

12
Q

used for directional drilling. the motor is mounted directly above the bit and is powered by the drilling mud. it turns the bit without the rotation of the drillstring.

A

down-hole mud motor

13
Q

these are attached to the hooks are used to lift the pipe string. they wrap around the pipe below the tool joint and latch, then lift against the upset shoulder.

A

elevators

14
Q

are used to hang the string from the rig floor. they wrap around the pipe, wedging it against a recess in the floor. when the string is picked up, the slips come free and can be removed.

A

slips

15
Q

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

A

tongs

16
Q

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

A

fingerboard

17
Q

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

A

rat-hole

18
Q

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

A

mouse-hole

19
Q

a device to multiply the lifting capacity of the drilling line

A

block and tackle

20
Q

?

A

drill block

21
Q

any substance that flows and yields to any force tending to change its shape.

A

fluids

22
Q

liquids and gases are

A

fluids

23
Q

the density measure used for petroleum liquids. expressed in degrees.

A

API (American Petroleum Instituted) Gravity

24
Q

The higher the API gravity the

A

lighter the liquid

25
Q

the minimum saturations of oil, water, or gas in the reservoir that cause the fluid to be a continuous medium, and therefore producible.

A

critical saturations

26
Q

defined as hydrocarbons that are in a gaseous state at standard conditions of 1atm (14psi) and 60degF.

A

petroleum gases

27
Q

methane, ethane, propane, and butane

A

petroleum gases

28
Q

gas that is in solution in the oil under the initial reservoir pressure and temperature. under these conditions, the gas is in the liquid stage.

A

Solution gas

29
Q

The percent or fraction of the reservoirs original oil in place (OOIP) or original gas in place (OGIP) that will be recovered.

A

recovery factor

30
Q

is from solely reservoirs where no “black”(non-condensate) oil is present

A

Non- associated gas

31
Q

includes solution gas and gascap gas. these two only occur in

A

Associated gas

32
Q

is free gas trapped in the top of the structure above the oil leg. when there is a ____ _____ the reservoir is at bubble point pressure.

A

Gas Cap

33
Q

ratio of gas to oil produced or in solution in the reservoir.

A

Gas Oil ratio (GOR)

34
Q

Beta is the factor for the volume change undergone by the reservoir fluids when they are produced.

A

Formation volume factor (B)

35
Q

A fluids resistance to flow. the thicker and stickier the fluid , the higher its _____. measured in centipoise

A

Viscosity (u)

36
Q

a light hydrocarbon liquid formed by condensation of petroleum compounds that were in the gaseous phase under initial reservoir conditions. it is highly volatile and from clear to a light yellow color

A

condensate

37
Q

when a reservoir is above its ___ ____ ____ , it has no free gas- all gas is in solution in the oil. as the reservoir is produce and pressure declines, the ___ ___ ___ is reached. gas comes of solution , forming a free gas saturation

A
