Limited Entry Acid Stimulation
Packers Plus RapidMATRIX® multi-stage completion systems are specifically designed for effective acid stimulation. Using limited entry, the RapidMATRIX system evenly distributes stimulation fluid across isolated intervals.
For each treatment zone, the RapidMATRIX system includes a number of QuickPORT™ sleeves flanked by RockSEAL® H2 packers. This configuration creates multiple, individually isolated treatment zones, or stages. Each treatment zone is activated by an actuation ball, which is available in multiple sizes, enabling several zones to be stimulated in succession. After stimulation, the well can be immediately flowed back and put on production.
Because the Packers Plus RapidMATRIX 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 RapidMATRIX limited entry system offers many features or benefits:
–Mechanical stage isolation with field-proven RockSEAL H2 packers
–Full stimulation coverage of entire horizontal
–Single, continuous pumping operation
–Consistent limited entry stimulation with QuickPORT sleeves
–Lower zones are isolated due to increasing ball size
–Immediate flowback after stimulation
–Improved production results
–Compatible with other Packers Plus tools and systems
The RapidMATRIX limited entry system can be used in many applications:
–Limited entry stimulation
–Horizontal and vertical wells
–Carbonate, sandstone, and naturally fractured formations
–Critical sour and HPHT
Implementing Packers Plus completion systems resulted in significant initial and final production rate increases, compared to historical production values from the area
RapidMATRIX increases production from carbonate formation
Practical Aspects of Multi-stage Fracturing
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 RapidMATRIX 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 QuickPORT sleeve is a ball-actuated, hydraulically activated injection/production port. This sleeve allows for more than one stage to be activated with the same size actuation ball for limited entry batch fracturing. The QuickPORT sleeve flow ports are available in a variety of sizes to optimize the limited entry fracture treatment.
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 Drillable Closeable (DC) version that can be re-opened for future operations.
Packers Plus successful stimulation services begin with a fully integrated quality assurance and quality control (QA/QC) process that begins at the design stage and follows each tool through manufacturing, assembly, testing, shipping and installation. Automation and robotics are incorporated into our proven process to ensure consistency and repeatability of key criteria in each step as we design, develop and manufacture our patented tools and systems. As a commitment to quality and meeting stringent standards, Packers Plus has achieved ISO 9001 certification and API Q1 Certification for our manufacturing and engineering operations in Edmonton, AB, and ISO 9001 in Houston, TX.
