October 29, 2012, Calgary, Alberta – Packers Plus Energy Services Inc. has been issued three Canadian patents covering its methods and apparatus of open hole multi-stage fracturing and completion that have transformed the development of tight oil and gas reservoirs throughout the world. The patents were originally applied for in 2002, and include ball-activated horizontal fracturing systems.
The three Canadian patents cover wellbore isolation, fluid treatment and ports that hydraulically open. The three patents are listed as follows:
Packers Plus Exhibits at Leduc #1 Energy Discovery Centre
The Leduc #1 Energy Discovery Centre is located on the site of Leduc #1, a historic well that shaped Alberta’s energy future when it began producing light crude oil on February 13, 1947. The centre provides educational programs about energy to hundreds of elementary and high school students every year. Packers Plus and the Leduc #1 Energy Discovery Centre are working together to highlight the importance of horizontal drilling and open hole, multi-stage fracturing to the oil and gas industry. Visitors can learn more about these important advancements by reading a poster display and following along with our StackFRAC animation.
Over the last several years, various companies have introduced competing systems that mimic the original Packers Plus design, suggesting they can achieve similar success. For many of these companies, the development of an open hole, multi-stage system was just an addition to a large list of offerings and has remained a very small focus within their overall operation.
In contrast, Packers Plus innovated open hole, multi-stage fracturing systems in 2001. Our development of this niche market, an area initially ignored by larger service companies, led to a decade of growth and additional production from resources previously thought to be unrecoverable. With a dedication to constant improvement of our systems, as well as the introduction of additional technology, Packers Plus remains resolutely focused on providing customers with a variety of solutions.
Our experience, quality assurance and quality control (QA/QC) process and reliable technology have allowed us to maintain our status as an industry leader. Packers Plus can improve your completion operation with:
Over a decade of experience, with 9,500 StackFRAC systems and over 108,000 stages completed worldwide
A fully integrated QA/QC process allowing us to quickly and accurately respond to customer needs
Field proven RockSEAL II packers that provide ease of installation, control and reliability to guarantee an effective seal and completion
Challenge the status quo and take your completion to the next level with Packers Plus.
Through years of experience and education, the oil and gas industry is learning that more stimulation intervals along the horizontal results in better production along the wellbore.
To help meet this need, our StackFRAC HD™ “High Density” system provides more stimulation intervals through improved staging technology. With the addition of RepeaterPORT® sleeves or by using our QuickFRAC® batch-fracturing system, you can further multiply the number of stages in each system. These technologies enable you to increase your production by running longer laterals with shorter stage lengths, while reducing costs by decreasing completion times and using less fracturing fluids.
Significant differences in completion philosophy are emerging within our industry. Even companies that practice a factory mentality (one size/method fits all) are beginning to see that the “sledgehammer approach” to hydraulic fracturing may not be the most effective in draining horizontal wells in resource plays. For several years, we have seen massive increases in fluid volume, pumping rate, total proppant volume, and pumping time to increase recovery. We have seen through microseismic as well as fracturing into offset wells, that we are able to create massive and extremely long hydraulic fractures. Yet, when effective fracture length is calculated, the results are extremely disappointing. It only makes sense that “more is better.” However, after years of steadily increasing job size, stage number, perforating strategy, proppant volume, and lateral length, the only one that stands out as consistently improving recoveries is that more stages are required to effectively drain microdarcy permeability rock (Rankin et al., 2010).
