Multiple Array Production Suite - Capacitance Array Tool (CAT)
Oil, gas, and water have different dielectric constants. The Sondex Capacitance Array (CAT004) Tool uses this property to identify fluid phases in high deviation and horizontal wells. Run centralised in the wellbore, the CAT is fully combinable with other Sondex UltrawireTM production logging tools.An array of 12 miniature sensors are mounted on the inside of a set of collapsible bowsprings and measure the capacitance of the surrounding fluid close to the well casing. All 12 values are simultaneously transmitted to the surface or into a memory section. Combined with data from the Spinner Array Tool (SAT), Gas Array Tool (GAT) and the Resistance Array Tool (RAT), the tool allows quantitative estimates of the volumetric flow rate for each phase.
Our MAPS logging technology offers an innovative range of tools with multiple sensors that provide a clearer and more accurate picture of the flow regime which is vital for superior reservoir management. MAPview creates 3D images of the flow regime to present a realistic analysis of a well’s production.
