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.
The four-arm device is fitted with Guardian’s unique ‘Proportional Blade’ technology allowing the spinner blades to rotate whilst the calliper arms close. This enables a range of tubing/casing to be logged using only a single tool. The CFF is fitted with Guardian’s industry standard MonoPin Bus (MPB) system. On-board temperature compensation ensures an accurate calliper measurement under all conditions.
A novel roller design minimises wear and reduces maintenance costs, whilst optional larger rollers ensure the optimum stand-off from casing.
