Providing Accurate PL Interpretation with Multi-probe, Multi-sensor Tools in Segregated Flow Environments

TL;DRAbstract

The newest production logging tools have multiple sensors that can provide valuable information concerning fluid types, fluid compositions, and fluid velocities, particularly in segregated flow environments. Since these tools include a relative bearing sensor, it is possible to determine where each sensor is located in the wellbore and flow stream. The interpretation of multiple sensors in a continuously changing wellbore environment required the development of software that combines navigational information about the location of the sensors in the flow stream, as well as data from the sensors relating to velocity and phase changes. The Capacitance Array Tool (CAT) and the Resistivity Array Tool (RAT) provide detailed information regarding the wellbore fluids either consisting of gas, oil, and water or combination. It is possible to distinguish the segregation of the phases from the tool orientation and sensor physics. The Spinner Array Tool (SAT) provides velocity information from the
