Answer 2

deflector flowmeter / diverter flowmeter

Question 3

The process of comparing and fixing measured depths with known features on baseline logs of the wellbore tubulars and the surrounding formation

Answer 3

depth correlation

Question 4

A record of the difference in temperature between two vertical points in a well

Answer 4

differential temperature log

Question 5

A record of the change in temperature along a well, normally recorded by a fiber-optic cable

Answer 5

distributed temperature log

Question 6

Pertaining to a technique in which a packer flowmeter is partially inflated and dragged up the hole to give a continuous flow log

Answer 6
