2010: WATCH FracPoint Openhole Fracture Completion System by Baker Hughes Inc.
FracPoint™ openhole fracture completion system precisely and reliably isolates multiple zones in open and cased holes. The system establishes openhole isolation between zones, zone lobes, or fault lines so fracture fluid is delivered where needed for maximum effect. Pinpoint fracture placements without cementing for improved initial productivity, accelerated reservoir drainage, and faster [return on investment].
2013: Birch Lake announces claim commenced by Bernum Petroleum
The Company has taken immediate steps to vigorously defend this claim and preserve its rights in the joint venture assets including a detailed review of the completion operations on the initial well which led to the apparent collapse of the production casing string during the frac operation and the resulting loss of more than half the productive well bore.
The Corporation is also conducting a detailed review of the drilling operations of the second well during which intermediate casing was not able to be successfully run to depth drilled, resulting in drilling difficulties during the horizontal section and the eventual loss of the horizontal section after nearly reaching total depth.
2013 05 21: AER (then ERCB) Releases Hydraulic Fracturing Deregulatory Directive 083
Another con job by the law violating, spying AER?
Further modifications were made to Directive 083 based on stakeholder feedback. Some of these modifications include:
Additional requirements for wellbore integrity, design and testing, including the option for single- and dual-barrier design.
The ERCB has observed that for hydraulic fracturing operations, there is an emerging trend toward the use of single-barrier wellbore construction, rather than dual-barrier construction, to provide a secure pathway for fluid injection and recovery from the reservoir. While the ERCB has had no reports of single-barrier well systems losing integrity, the introduction of enhanced ‘Optional” regulations will provide an added measure of protection.
The ERCB believes that the risks to well integrity associated with single-barrier well systems can be effectively managed by an operator. The new directive requires licensees to demonstrate that operational risks have been considered in the selection and design of the wellbore construction and to monitor and test to ensure that well integrity is maintained. [How does “considering” something ensure anything? Nice deregulatory loophole for industry by the AER]
These testing requirements will provide the ERCB with the appropriate information to monitor and assess the behaviour and responsiveness of single-barrier systems undergoing hydraulic fracturing and readjust requirements if required. [More deregulation?]
Was the industry controlled and financed AER paving the “optional” way for extreme open hole completions like this below?

Nine Energy Completes First 50 Stage Divert-A-Frac System by CNW News Wire, February 23, 2016
HOUSTON, Feb. 23, 2016 /CNW/ – Nine Energy Service, Inc. (Nine) successfully completed their first 50-stage Divert-A-Frac open hole system for a large, global independent operator in the Williston Basin.
All 50 stages were successfully placed and the stimulation job was completed as designed with a total of 3.5 MM lb proppant and 52,300 bbl fluid. The stimulation took just over 50 hours, averaging ~1 hour per stage, with zero non-productive time (NPT) related to the system operation.
“The operator was looking for a single-point entry solution to significantly increase their stage count from 35 to 50 without resorting to limited entry cluster stimulation,” said Rickey Green, Vice President for the Rocky Mountain Region. “This success was a result of detailed testing and analysis of Nine’s Divert-A-Frac Port Sub (DAFPS-III) frac sleeve to confirm the 50-stage design was sound.”
Rickey and his team worked closely with the operator to engineer the system for their 10,000-ft laterals. The DAFPS-III frac sleeves were pressure tested with dissolvable metallic actuation balls, and computational fluid dynamics (CFD) analysis demonstrated that ball-on-seat performance would not be affected by the planned proppant stimulation in the 50 sleeve system.
“This success demonstrates Nine’s ability to engineer and execute a customized solution to fulfill operator needs,” said Ann Fox, President and CEO. “We are proud of our team and we continue to invest in talented people who deliver exceptional results.”
The Divert-A-Frac open hole system 50-stage sleeve capability will enable operators working in the Bakken and other formations to stimulate their wells with more stages, at higher rates with more control over fracture initiation and propagation than with traditional cluster stimulation.
