Quantifying flow at any deviation in complex completions
The PS Platform integrated production services platform can log in
boreholes at any deviation to provide three-phase flow profiles and production
monitoring and diagnostic information. Measurements can be made in real time or
Engineered for high-angle and deviated wells, the intelligent MaxTRAC
downhole wireline tractor acquires well data in downward and upward passes,
easily negotiating changes in well diameter and complex completions. The
MaxTRAC tractor is readily combinable with the PS Platform platform and shares
the same telemetry.
Tractoring and anchoring to log complex flow conditions
Previous production logging indicated that the gas entry points were
13.5 and 25.9 m from the top of the ICD straddle. Because the MaxTRAC tractor
shares telemetry with the PS Platform platform, Statoil took advantage of this
compatibility to record data by positioning the tractor below the production
logging tools. The PS Platform platform’s wiring was modified to
pass 1,000 V for tractor operation.
The PS Platform platform toolstring was positioned inside the reduced
diameter of the ICD straddle and the tractor anchoring the toolstring was
positioned in the larger diameter screen section below the ICD. This
configuration enabled data collection despite not being able to record a
continuous pass inside the ICD.
Real-time flow data was collected for remote analysis through the
InterACT global connectivity, collaboration, and information service. Internal
and tubular changes along with compression and tension were also monitored to
determine the lifting forces exerted on the tools above the anchored tractor.
Data was successfully acquired at multiple flow rates above, below, and within
the ICD straddle to effectively diagnose the gas entry points in the well.
