Integrate datasets to improve rig-up efficiency and downhole
The time of delivery of plug debris to surface was computed from the
time when the plug was tagged and milled and the history of the return rate,
which was measured with the Vx Spectra flowmeter. The Vx Spectra flowmeter is
an ideal tool for diagnosing well behavior during plug drillout operations. An
additional level of control is provided by differential pressure measurements
across the plug catcher. As a result of the implemented procedure, the operator
precisely knew when plug parts would return to surface. Combination with data
from coiled tubing and information on the depth of each plug gave the operator
a high-resolution view of downhole activities.
Schlumberger provided full operational support to the field operations,
working together to process and combine the Vx Spectra flowmeter data with the
coiled tubing and flowback data. The operator used the results from the Vx
Spectra flowmeter to identify and optimize the surface equipment layout and
procedure for well control.
