Definition: 
Calliper Fullbore Flowmeter
Subject Area 1: 
Logging & petrophysics
Subject Area 2: 
A tool name
Remarks: 
The CFF combines a two-axis (X-Y) calliper with a fullbore flowmeter in a single, short logging tool. The spring cage of the flowmeter provides sufficient centralisation force to eliminate the requirement for a lower centraliser when deployed with a typical production logging string.
