Operator seeks long-term monitoring without regular intervention
ConocoPhillips required long-term production monitoring to analyze
completion effectiveness, reservoir depletion, and zonal flow contributions for
wells located within the Barnett Shale formation. The conventional approach for
horizontal wells required separate production logs over different time periods
to evaluate changing well performance.
Integrated service uses fiber-optic telemetry
To minimize required time downhole for collection of well data,
ConocoPhillips chose to explore and evaluate the use of fiber optics.
Conventional methods required data collection of DTS measurements in two
separate runs; the first run would be completed using a fiber
optic–enabled CT for DTS, and a second run with an electric line inside CT
for production logging. Using the ACTive PS service, ConocoPhillips acquired
both DTS and Flow Scanner horizontal and deviated well production logging
system measurements in one run.
As part of the ACTive family of live downhole coiled tubing services,
ACTive PS service uses fiber optic–enabled telemetry and downhole wireline
data conversion to deliver high-quality, real-time data for tools
conventionally only available in memory mode or with live telemetry via
ACTive PS service optimizes logging techniques, saving time and
ConocoPhillips required DTS and Flow Scanner system logs, and ACTive PS
enabled real-time telemetry to surface, eliminating the use of wireline logging
cable–equipped CT and capturing both logs in a single run. This technique
reduced time, risk, and cost, ultimately providing two logs without tripping CT
in and out of the well to switch CT strings.
