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 Owen Instrumentation’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 Owen Instrumentation’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.
Product features
-
Combines independant X & Y caliper measurements with Fullbore Flowmeter to reduce tool length and cost.
-
Large range of ID's can be logged with a single tool due to unique 'Proportional Blade' design.
-
Bearing design in rollers reduces friction for better deployment in high deviated wells.
-
More accurate flowrate calculation due to well cross sectional area measurement from XY caliper.
Product Application
-
Wells where flow needs to be logged through multiple diameters or where is uncertainty about well ID.
-
Rigups where tool length needs to be kept to a minimum.
-
High flow rate injection wells where there is a concern about flowmeter being blown closed.
