PRODUCTION LOGGING-Conclusion: Two more options correct fluid-density logs for friction

Two more methods for correcting friction effects on differential-pressure density logs from wells with high flow rates are third-party software and a nonlinear regression method.Friction affects production logging tool response by causing the apparent density of the downhole fluid mixture to appear greater than it actually is. If these logs are not corrected properly, one may make inappropriate decisions, based on incorrect analyses, possibly leading to unnecessary workovers and reservoir mismanagement.This third and concluding article in a series discusses third-party software and provides an elegant nonlinear regression method for accurately correcting these logs for friction effects.Pa...
