PART 6

Question 1

A multiphase flow regime in pipes in which most of the gas moves as large bubbles dispersed within a continuous liquid

Answer 1

plug flow

Question 2

A record of one or more in-situ measurements that describe the nature and behavior of fluids in or around the borehole during production or injection

Answer 2

production log

Question 3

A record of the difference in temperature between the opposite sides of the internal wall of a casing

Answer 3

radial differential temperature log

Question 4

A record of the presence of tracer material placed in or around the borehole to measure fluid movement in injection wells

Answer 4

radioactive tracer log

Question 5

A technique for interpreting the results from a spinner flowmeter using only one logging run over the zone of interest

Answer 5

single pass method

Question 6

The only component of a flow or other phenomenon, normally oil, water or gas

Answer 6

single phase

Question 7

The phenomenon in multiphase flow when one phase flows faster than another phase, in other words slips past it

Answer 7

slip

Question 8

The difference between the average velocities of two different fluids flowing together in a pipe

Answer 8

slip velocity

Question 9

A multiphase-flow regime in pipes in which most of the lighter fluid is contained in large bubbles dispersed within, and pushing along, the heavier fluid

Answer 9

slug flow

Question 10

A device for measuring in situ the velocity of fluid flow in a production or injection well based on the speed of rotation of an impeller, or spinner

Answer 10

spinner flowmeter

Question 11

The change in direction of rotation that occurs when a spinner flowmeter tool is moving in the same direction, but faster, than the fluid

Answer 11

spinner reversal

Question 12

A multiphase-flow regime in horizontal or near-horizontal wells in which the fluids are separated into different layers, with lighter fluids flowing above heavier fluids

Answer 12

stratified flow

Question 13

The velocity of fluid moving through a pipe, defined as the volumetric flow rate of that fluid divided by the cross-sectional area

Answer 13

superficial velocity

Question 14

Referring to the description of different regimes for the simultaneous flow of gas and liquid in vertical pipes introduced by Y

Answer 14

Taitel Dukler

Question 15

In multiphase flow, large bubbles of the lighter phase that form by coalescence of small bubbles under certain conditions of fluid flow

Answer 15

Taylor bubbles
