Flagship measures water flow velocity by WFL mode and accurate water holdup by Floview electric probes,then the flow profiling of the horizontal wells is obtained by interoperating the logging data,hence to find the main water influx interval.

Flow Scanner: A new flow tool for production logging in horizontal wells;

Estimation of oil-water relative permeability curves from production logging data;

Identify fluid property in fractured reservoirs by production logging;

Sun Workstation Used as A Production Logging Interpretation System;

This paper gives particulars of several methods of re-evaluating the structures by utilizing the performance data such as production log data, RFT data, tracing monitoring data, residual oil monitoring data, deviation repetition measurement .

This paper introduces the production log technology used in NIOC(S)oil field and describes the method used to identify problems in the flowing well by using production log technology, and presents the effectiveness of the method utilized to find the problems in the flowing well in combination of the wellsite typical production logs.
