Open Hole Multi-stage Completions
The Packers Plus StackFRAC® HD multi-stage completion systems are designed for open and cased hole stimulation in unconventional tight oil and gas formations. This innovative, field-proven system allows for exact placement of stimulation treatments in one continuous pumping operation. Once the stimulation operation is complete, the well can be immediately flowed back and put on production. StackFRAC HD systems provide operators with an efficient and cost-effective method to complete their wells.
Because the Packers Plus StackFRAC HD system is modular with regard to tool placement, it can be combined with other Packers Plus tools and systems, enabling customized design for targeted delivery of the stimulation program.
The StackFRAC HD multi-stage completion system offers many features and benefits:
–Mechanical stage isolation with field-proven RockSEAL® H2 packers
–Continuous rigless pumping operation reduces completion time and cost
–Access to natural fractures in open hole applications
–Full coverage in extended reach horizontal wells
–Custom stimulation of the entire wellbore
–Immediate flowback after stimulation
–Improved production results
–Compatible with other Packers Plus tools and systems
The StackFRAC HD multi-stage completion system can be used in many applications:
–Open and cased hole horizontal and vertical wells
–Pre- and post-stimulation production testing
–Tight oil and gas formations
–Critical sour and HPHT environments
–Extended reach horizontal wells
The RockSEAL H2 packer is a hydraulically set, mechanical packer. The dual-element design, along with premium seal technology, ensures reliable high-pressure zonal isolation during stimulation and throughout the life of the well. The RockSEAL H2 packer offers ease of installation through its short length, minimum outside diameter and anti-preset features. Hydraulic activation allows for precise control over the setting operation, resulting in time and cost efficiencies.
The RockSEAL llS is a single-element, double-grip, hydraulically set retrievable open hole packer. It maintains the proven mechanical and element system of the dual-element packer along with an added anchoring capability. The anchoring slip design allows the packer to anchor the StackFRAC HD system at the toe of the well, wellbore junctions or other areas that require extra stability. This packer is typically run in conjunction with the RockSEAL H2 packer for added sealing capability, but can be used on its own as required.
The FracPORT™ H2 sleeve is a ball-actuated, hydraulically activated injection/production port. This sleeve is run between two RockSEAL H2 packers to allow specific zones of the wellbore to be isolated and selectively stimulated. By providing a flow area greater than the liner, the FracPORT H2 sleeve provides unrestricted flow for stimulation treatments. The FracPORT H2 sleeve is also available in a Drillable Closeable (DC) version that can be closed or re-opened for future operations. This allows for effective water or gas shutoff, flow control, re-fracturing and production testing.
The Hydraulic FracPORT sleeve is a hydraulically activated injection/production port used for the first stage of all Packers Plus stimulation system applications. This sleeve opens at a specific pressure allowing communication between the tool string and the annulus. The unique configuration of the Hydraulic FracPORT sleeve ensures full opening for effective stimulation of the first stage. The Hydraulic FracPORT sleeve is also available in a DC version that can be closed and re-opened for future operations.
In addition to the production benefits achieved by the StackFRAC completed well, the fracture treatment was completed in a third of the time
Packers Plus operational experience helps improve production
Overall production with StackFRAC HD technology was up to 36% higher
