OPERATION
The Lee Energy Systems’ PPT Gator Perforator allows operators to perforate multiple zones and see individual zonal injection rates on one trip. The system can be run on jointed pipe or coiled tubing.
• Run in hole to desired depth straddling the packers over the
intended stim zone.
• Circulate through the VCV at specified rate.
• Activate Packers by flowing at specified rate to close VCV &
within the rate window for zonal stimulation.
• To deactivate packers, simply kick out the pumps. The packers
will retract to their original position.
• Allow time for annular equalization and pull to the next stage.
• Repeat Activation, Stimulation, and Deactivation sequence for
all intended zones.
• When stages are complete, pull out of hole.
