Question 1

A multiphase flow regime in which the lighter fluid flows in the center of the pipe, and the heavier fluid is contained in a thin film on the pipe wall

Answer 1

annular flow

Question 2

A technique for recording sound at different positions in the borehole to generate a noise log

Answer 2

audio measurement

Question 3

A device for measuring in situ the velocity of fluid flow in a production or injection well in which the flow is diverted through the spinner by a set of metal vanes, or petals

Answer 3

basket flowmeter / petal basket flowmeter

Question 4

A small, radioactive plastic sphere that is insoluble and used to make a tracer-loss measurement

Answer 4

bead tracer

Question 5

Referring to the flow of two immiscible fluids, oil and water, oil and gas, or gas and water

Answer 5

biphasic

Question 6

The frequency with which a local probe detects a change from one type of fluid to another

Answer 6

bubble count

Question 7

A multiphase flow regime in pipes in which one fluid moves as small dispersed bubbles through a continuous fluid

Answer 7

bubble flow / dispersed bubble flow

Question 8

An in situ record of the capability of the fluid passing through a sensor to store electrical charge

Answer 8

capacitance log

Question 9

Another term for holdup meter, a device for determining the waterholdupin aproducing wellby measuring the capacitance or impedanceof the fluid

Answer 9

capacitance meter

Question 10

An in situ record of casing thickness and integrity, to determine whether and to what extent the casing has undergone corrosion

Answer 10

casing inspection log

Question 11

An in situ log of the electrical potential on the inner wall of a casing

Answer 11

casing potential profile

Question 12

A technique in which a slug of material is introduced into the flowstream of a producing well to determine the flow rate of one or more of the fluids

Answer 12

chemical marker injection

Question 13

A multiphase flow regime in near-vertical pipes in which large, irregular slugs of gas move up the center of the pipe, usually carrying droplets of oil or water with them

Answer 13

churn flow / froth flow
