Systems / Stimulation / Straddle Cased Hole Packer Coil
The Straddle Cased Hole Packer combines two Speed Squeeze Packers above and below the Nozzle Stim Sub, with an optional Unloader Sub for added circulation. The SYSTEM can be run to create limitless perforation zone density in cased hole operations.
- 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.
