To design accurate inflow control device (ICD) completions in high water cut wells, it is critical to have a thorough understanding of the downhole flow profile and zonal phase contribution across the zone of interest. The situation becomes more complex when dealing with an open hole horizontal section with complex trajectory, where the presence of stagnant water sumps and oil humps is common and can lead to in-accurate determination of water and oil entry zones. Production logging tools typically deployed in such environments will require to have their data quality checked, as the well conditions can either leave the spinners clogged or the holdup probes sticky with downhole debris or emulsion. Production logging tools will also need to reach the deepest point within the lateral section to ensure complete coverage of the potential flow area across the open hole section. Electrical line enabled coiled tubing (CT) technology was considered to overcome the conveyance challenges to deploy these production logging tool. The selected rugged design of the coil-to-wireline interface increased the reliability and the safety of the intervention. In this paper, a case study will be presented detailing how careful operational planning, integration between the conveyance method and the production logging tool resulted in the detailed and accurate downhole flow profile, which was then utilized in the ICD design for this well.
