Answer 5

Derrick

Question 6

steel wire rope

Answer 6

drilling line

Question 7

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

Answer 7

drawworks

Question 8

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

Answer 8

crown block

Question 9

attached to the traveling bock and supports the load

Answer 9

Drilling hook

Question 10

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.

Answer 10

conventional rotating system

Question 11

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.

Answer 11

Power swivel

Question 12

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.

Answer 12

down-hole mud motor

Question 13

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.

Answer 13

elevators

Question 14

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.

Answer 14

slips

Question 15

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

Answer 15

tongs

Question 16

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

Answer 16

fingerboard

Question 17

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

Answer 17

rat-hole

Question 18

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

Answer 18

mouse-hole

Question 19

a device to multiply the lifting capacity of the drilling line

Answer 19

block and tackle

Question 20

?

Answer 20

drill block

Question 21

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

Answer 21

fluids

Question 22

liquids and gases are

Answer 22

fluids

Question 23

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

Answer 23

API (American Petroleum Instituted) Gravity

Question 24

The higher the API gravity the

Answer 24

lighter the liquid

Question 25

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

Answer 25

critical saturations

Question 26

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

Answer 26

petroleum gases

Question 27

methane, ethane, propane, and butane

Answer 27

petroleum gases

Question 28

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.

Answer 28

Solution gas

Question 29

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

Answer 29

recovery factor

Question 30

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

Answer 30

Non- associated gas

Question 31

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

Answer 31

Associated gas

Question 32

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.

Answer 32

Gas Cap

Question 33

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

Answer 33

Gas Oil ratio (GOR)

Question 34

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

Answer 34

Formation volume factor (B)

Question 35

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

Answer 35

Viscosity (u)

Question 36

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

Answer 36

condensate

Question 37

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
