The well produced by ESP with a gross rate of 120m3/d and water cut of 80%. Completion of the well is the 5” selective string across the reservoir zone with 8 frac ports separated by open hole packers. Eight stages hydraulic fracturing job was performed in this well some time ago. The challenge for North Side was to perform Production logging survey in a well-flowing mode using FlowJet® pump to lift the well and run MPLT tools for reservoir performance evaluation across ports.
Methodology of Solution
A workover rig was mobilized to the well and pulled ESP. FlowJet® pump run into the well. North Side performed production logging survey in static, flowing and transient modes using FlowJet® pump as a lifting tool during MPLT. The interpretation of the MPLT results is brought below.
