Question 5

A neutron porosity log recorded while the well is flowing to determine the gas-oil contact in the borehole

Answer 5

flowing neutron log

Question 6

A record of the density, or changes in density, of fluids in a production or injection well

Answer 6

fluid density log

Question 7

An in-situ measurement of the flow profile made by pumping different fluids down the tubing and casing and observing the interface between them

Answer 7

fluid interface log

Question 8

A distortion of the magnetic flux that has been introduced into a casing by a low-frequency electromagnet or permanent magnet

Answer 8

flux leakage / magnetic flux leakage

Question 9

commonly deployed for offshore production in locations that have little infrastructure

Answer 9

FPSO / floating production, storage, and offloading vessel

Question 10

In a gradiomanometer tool or pressure derivative calculation, the apparent increased fluid density observed due to frictional pressure losses along the tool and casing in a fast-flowing fluid

Answer 10

friction effect

Question 11

A type of flowmeter in which the spinner blades are collapsed to pass through the tubing and other restrictions, and then opened up below to sense the full cross section of the casing or openhole

Answer 11

fullbore spinner

Question 12

A device for measuring the density of fluids in a completed well, using a radioactive source of gamma rays and a detector
