CADE’s mandate is to provide high-quality technical
meetings to promote awareness of the drilling &
well servicing industry. Through CADE, members
and the public can learn about the technical chal-
lenges and experience gained from our speakers,
who are most often CADE members themselves.
We invite you to join CADE and further your profes-
sional development.
Past issues of CADENews are available online.

President’s MessageThis will be my last President’s Message for the Canadian Well Construction Journal, as Eric Schmelzl will be the president for the 2011-2012 year starting in September. I would like to take this time to thank all of the current executives at CADE—there have been many changes in the association and without the support of the executives, your association would not have had the successful year that is has.
One of the highlights for CADE this year included developing a strong relationship with both the University of Calgary and SAIT Polytechnic, relationships I will continue to strengthen as the past president of CADE. I have also invited a graduate from each school to work with me as liaison with their respective schools to establish a legacy with CADE.
This year CADE has worked hard to involve student groups as much as possible. The first CADE/U of C/SAIT student industry mixer was held in January and by all accounts was a huge success. The event was organized by the students and, in particular, Ramez Hanna Alla did a lot of work on the project and should be congratulated.
The incoming executive from the Petroleum and Energy Society at U of C (Joseph Lagasca, Ben Russell, Omar Moussa and Allison Yuen) asked me what benefits CADE garners from a relationship with our student members and vice versa, what benefits do our student members receive. In my opinion, as a professional engineer, I have to pay it for-ward and mentor the people entering our industry so the same mistakes that I made in the past are not repeated in the future. Sort of knock the sharp points off of the learning curve.
CADE has the ability to educate our membership with the monthly technical lunches and other events such as the Drilling Conference. When I meet and talk with our student members, they are keen on the drilling and completion side of the business, but I believe it is CADE’s responsibility to introduce our membership to the different and varied aspects of the business. Not everyone will be as interested or as fortunate as I have been in my career, and run drilling and completion operations. There is a multitude of opportunities existing in the entire field, from pumping, to tools, to rig design. The list goes on and on, and we need to introduce our members to these opportunities.
CADE benefits with a first look at the new crop of engineers and technologists as they prepare to graduate. With upcoming shortages of technical people, this represents a definite advantage for operators in particular as they find themselves having to market themselves to attract talent.
Again, thanks to the CADE executives for their support in the past year, never dull and always dynamic. Thanks to the members for their support in attending the luncheons, the drilling conference and the other functions hosted by CADE. And thanks also to all the volunteers who have made the past year so successful. I am looking forward to the next year and the direction your association is taking.

Editor’s Note
Welcome to the June issue of the Canadian Well Construction Journal. Well, breakup is done, depending on where you are working, and summer is right around the corner, hopefully. Road bans are coming off, equipment is moving and field staff can’t get hold of office staff as they are all rushing to the golf course. The summer, it seems, is gearing up to be just as busy as predicted going into breakup, which given where we were two summers ago is a relief for most.
This is our last issue until September and we have an article from Godfrey Budd relating to a huge driver of activity in the western Canadian oil and gas industry, horizontal drilling and completions.
We are continuing to review ideas for the 2011 technical luncheon presentations, as well as story ideas for the journal. Please don’t hesi-tate to contact us if you have any ideas for upcoming topics or issues you’d like to see presented at the luncheons or in print. We hope you, the members, will participate and continue to make these events interesting and successful. If you have any issues you’d like to see covered, please email me and we will do our best to get the story.
Don’t forget, we would like to publish any of your information and announcements on new products, new technologies and senior personnel changes for publication each month. Please forward any announcements to us, as we would be excited to run them in our new feature section.
We appreciate your continued support and look forward to seeing you at the upcoming luncheons.

After nearly three decades at the helm of the Canadian Association of Oilwell Drilling Contractors (CAODC), president Don Herring is retiring.
“I believe it’s a stronger, more cohesive industry today than it has ever been, and I think it will continue to strengthen,” says Herring, 64, reflecting back on his tenure at the CAODC, which represents drilling contractors and service rig contractors in Canada.
CAODC’s connection with CADE goes back to 1974, when a group consisting of drilling engineers from operating com-panies, and from CAODC’s board of direc-tors, formed CADE. Founding members included Dale Christensen, with Gulf Oil; John Niedermaier, a drilling contractor with Commonwealth Hi-Tower Drilling, who served on the CAODC board; Rod Edgecombe of the Energy Resources Conservation Board (ERCB); Sid Robertson of Pajak Land & Offshore Ltd.; Jack Williams, a drilling contractor with Adeco Drilling and Engineering, and also a mem-ber of the CAODC board; Helmut Rath, of Shell Canada; Leroy Field, of Amoco Canada; and Vince Purdy.
“We have had a strong relationship with CADE ever since,” Herring says, noting that a volunteer from CAODC—often a member of the CAODC board of directors—has al-ways sat on the CADE board.
CAODC has served as CADE’s secretariat, providing administrative support, since September 1991.
In 1985, the two associations estab-lished the biennial CADE/CAODC Drilling Conference. When it first started, the tech-nical conference received direct financial support from the ERCB, but over time that support was not necessary, so the ERCB has stepped back. Since 2008, the CADE/CAODC
Drilling Conference has been held every year, with an average attendance of 350.
A trade association with responsibility for lobbying various levels of government, CAODC is focused on finding solutions to problems. These would include tax issues or operational problems—for example, transportation of dangerous goods mat-ters, or health and safety legislation.
“We have worked to establish standards that make it a little easier for people to compete and conduct business,” Herring says. “My real focus is on trying not only to improve the standards by which drilling companies work, but also to try and influ-ence the cost base, to make it a little more efficient for them to conduct business, and to make noticeable differences in how they can actually operate.”
As an example, CAODC has been very focused on such things as workforce training, safety issues and technical is-sues—such as how equipment performs, ensuring that it meets regulatory require-ments—and in many cases, trying to lead the regulations.
Among the hallmarks of Herring’s time with the CAODC has been the establish-ment of the rig technician course as a trade for drilling contractors, and the establishment of a competency program that is also an industry standard for service rig contractors.
“There have been a number of things like that, that make the Canadian industry

unique and a standard setter for drilling operations in the world,” Herring says.
“What makes the CAODC stand out is that it has a very dedicated and knowledge-able group of volunteers on the commit-tees and on the board of directors,” Herring says. “That, combined with a talented and supportive staff, makes the organization’s accomplishments noteworthy.”
Born in Calgary, Herring grew up in Alberta and Saskatchewan, and obtained a Bachelor of Commerce degree from the University of Alberta and a Master’s degree in economics from York University. He worked for Amoco Canada as a tax ac-countant; for the federal government in Energy, Mines and Resources; for the ERCB as an economist; and for Alberta Energy and Natural Resources a senior economist and director of resource economics do-ing oil policy. During the National Energy Program, he was involved in negotiating pricing agreements with Ottawa. In 1983, he joined the CAODC.
The CAODC expects to have found a replacement for Herring by the first week of June.
“I very much enjoyed the individuals and the challenges of working with [the CAODC], and trying to help out in address-ing their concerns,” Herring says.
After his retirement at the end of August, Herring plans to travel to Europe, do some woodworking, and eventually do more travelling around the United States.

By the end of 2009, United States natural gas proved reserves had increased by 11 per cent over 2008 to 284 trillion cubic feet, the highest level since 1971, according to the U.S. Energy Information Administration (EIA). A climb in shale gas reserves from 34.4 trillion cubic feet at year-end 2008 to 60.6 trillion cubic feet at year-end 2009 accounted for the lion’s share of the increase.
The increased importance of shale gas within the U.S. energy reserve/production picture and, in Canada, the success of shale plays in the Montney and Horn River, would have remained mostly a pipe dream were it not for advances in horizontal drilling, hydraulic fracture stimulation and completion technologies. Now that the tools and technologies are being widely applied, sometimes with the help of microseismic mapping and monitoring, petroleum engineers are working to figure out ways to make the best use of them.
This is no simple challenge. Experts agree that there is a need for better understanding of the geomechanical effects of unconventional well fracking, and the performance of individual frac stages, increased data gathering, sharing and integration, and new predictive software.
What is already clear to many shale specialists is that good fracture design can play a pivotal role in a successful completion program, even though, as some say, “hydraulic fracturing is a very forgiving technology.”
Completion road mapDespite its limitations, the currently available data can be distilled into some helpful principles for completions in shale plays, according to a

paper presented at the Canadian Unconventional Resources & International Petroleum Conference in Calgary last October. Based on the history of 16,000 frac stages in the Barnett, Woodford, Haynesville, Antrim and Marcellus shales, the paper proposed “a road map for effective completion practices for shale stimulation.”
The paper lists factors that it says operators should consider when planning a well in a shale formation. The first three (of nine) are:• Each shale play is unique, and therefore the completion design
evolves during the reservoir cycle.• Each shale play is heterogeneous, so a normal variation in
reservoir quality and production outcome will exist even in a closely-spaced area.

best choice• Hydrocarbon storage and production mechanisms are unconven-
tional and not well understood; therefore, the completion strategy and outcome are complicated.Principles like these certainly appear to be in line with the thinking
of some petroleum engineers and frac specialists. “The Barnett is the most well-known shale play, and quoted around
the world. It was the first time that shale showed real potential. Where the industry has run into problems is in adopting a factory approach, in effect dumbing down the [existing] technical competence,” says Dan Themig, a petroleum engineer and chief executive officer of Calgary-based Packers Plus Energy Services Inc.
Minimizing the number of technical people on frac jobs, along with a one-size-fits-all approach, resulted in horizontal fracking prac-tices that were inefficient and ineffective on some completions in the Barnett, Haynesville and other shale plays, he says.
Themig has advanced the view that high-density, open-hole (OH) fracturing systems that “allow more than 20 fracture treatments in a single, seamless operation” can address some of these problems, as well as cut costs and improve recovery.
There are two main methods for multistage fracking. The more traditional one involves first cementing the casing in the horizontal wellbore and then running a “plug-and-perf” stimulation for the desired number of stimulations.
Themig says that one of the problems with this is that to really make sure the perforation, and therefore the frac, is optimally placed in the wellbore, “sophisticated log data for where to per-forate” is usually required. This, he notes, is costly, but is locating
perforations based on assumptions, or according to a one-size-fits-all approach.
The open-hole multistage (OHMS) method, which was first used in 2001, doesn’t
involve cementing the casing, but instead uses external
packers that can create
a seal between the casing and the wellbore, with two or more packers along the casing isolating sections of the annulus for fracturing.
OHMS might obviate some of the need for costly, sophisticated log data, and the thinking on how far apart to space the packers has been evolving as a result.
In the early days of multistage fracs in the Bakken play, Themig says, “people said you must frac a small area [at a time], have the packers close together and force the frac out into a narrow area. But then people found that a frac on a wider area, with packers, say, 100 metres apart, not 10 metres…fracs did better. The pressure found the weakest rock, the sweet spot.”
oHms frackingIn the Bakken, Packers Plus has provided equipment and frac services for some very long laterals, including one in North Dakota that was 12,500 feet long with 47 frac stages.
Fracs in the Bakken, whether in North Dakota or Saskatchewan, have been more successful than was expected five years ago. But some gas shales have not delivered as expected, prompting operators in the Barnett, Haynesville, Marcellus and Montney to switch to OHMS fracking, which Themig believes will improve their production.
A paper by Themig published in the May 2010 Journal of Petroleum Technology included a comparison of three-year cumulative pro-duction data from two direct offset wells in the Barnett shale: one was cased cement, the other OH. According to one of the charts in the paper, recovery over a three-year period was about 50 per cent greater for the well that had used the open-hole method.
“In part, the differences in ultimate recoveries are due to the prefer-ential increase in productivity in OH versus cased-hole completions. In addition to this, however, a return to good fracturing practices that the industry had accepted 10 years ago may also be responsible for the stark contrast in ultimate recovery data,” Themig wrote.
For some operators, the tide of debate around the best completion methods for shale plays is turning in favour of OHMS. In the Anadarko Basin’s Granite Wash formation, a tight gas reservoir that has shown excellent rates of return, the best way to complete wells there has also been a subject of some debate, according to Jason Edwards, the comple-
tions manager for Jones Energy Ltd.Located in the northern Texas Panhandle and
western Oklahoma, the Granite Wash’s tight sand gas reservoir occurs in thick, stacked sequences of sand separated by shale. It is

in several zones at depths from 9,000 to 12,500 feet, with productive intervals of up to 400 feet in some areas. Gas from the Granite Wash has been successfully produced with both vertical and horizontal wells, but Edwards and his colleagues at Jones Energy have analyzed 25 wells, all drilled horizontally over the last three years, with about half of them cement-cased and the other half open-hole. Some high-rate wells in the Stiles Ranch area are producing in the 20 million cubic feet per day range, while elsewhere, initial production rates range from a few million cubic feet per day to 10 million cubic feet per day. “Economically, these wells compete head-to-head with those in the big shale plays,” says Edwards.
The Jones Energy study found that OHMS had a big cost advantage over plug-and-perf with a cemented liner. A frac completion with OHMS cost on average US$1.12 million, compared with US$1.58 mil-lion for plug-and-perf.
“Most of the difference in cost is made up from the time involved with plug-and-perf,” Edwards says. “It takes three to five days on 10 stages, with three perforation clusters per stage for a total of 30 fracs. But with ball-drop OHMS, 20 fracs can be done in 24-36 hours.”
The study suggests that up-front costs are higher using OHMS, but are offset by reduced costs associated with the amount of time saved and by the prospects of increased production performance, based
“in part, the differences in ultimate recoveries are due to the preferential increase in productivity in open-hole versus cased-hole completions.”

on cumulative production for the first year, rather than on expected ultimate recovery.
According to the study, the OHMS completion method outperformed the plug-and-perf method by 33 per cent over 12 months of production.”
Adding reservesMultistage horizontal fracking (MSHF) looks set to bring much more exploration and production activity to the fringe areas of the Cardium formation, a somewhat-neglected horizon in the conventional oil sector, which is now attracting interest.
The Cardium has an estimated 10 billion barrels of original oil in place (OOIP), of which about 1.75 billion barrels have been produced since the start of production in 1957. Until recently, production has been with primary, secondary and tertiary recovery from vertical wells.
Since late 2008, however, MSHF has been hugely successful in opening up parts of the Cardium that were previously considered to be uneconomic to develop with vertical wells, according to a recent Society of Petroleum Engineers (SPE) paper.
“The thickness in the fringe areas is from one to 10 metres. The pay zone in the main pool has about the same thickness range, but the fringe areas are mostly at the low end, with less permeability, but fairly good porosity, although not as good as the main area. But horizontals can make the fringe areas economic,” says Ese Omatsone, a petroleum engineer at Sproule Associates Limited, and principal author of the SPE paper.
The fringe areas hold an estimated one-to-three billion barrels of OOIP. “This is above the 10 billion OOIP of Cardium. Assuming 1.5 billion OOIP, developing 70 per cent of that would produce 126 mil-lion barrels, based on 12 per cent recovery,” she says.
In this, as in many of the shale plays, there is an ongoing need for stra-tegic data gathering and information, and it is possible that costs could rise in the Cardium, as they have in the Bakken shale-oil plays. When Cirque first drilled the Bakken in 2008, it cost about US$4 million to drill and complete a well. Today, it can be as much as US$5.5 million.

Horizontal drilling and multistage fracs have opened up new shale and tight gas plays, like this one in northeastern British Columbia.

Rigging upPrecision Drilling confident of future,
launches plans for another 16 new rigsBy James Mahony
Canada’s largest contract-driller will add 16 more rigs to its fleet, raising capital spending 54 per cent in the process.
At its annual meeting in Calgary in mid-May, Precision Drilling Corporation executives said the company would expand its new-build program for 2011 to 28 Super Series drilling rigs from the 12 rigs announced ear-lier. At the same time, the contractor will boost this year’s capital spending to $790 million from the $514 million previously announced.
Of the 16 new rigs in May, three are Super Singles destined for Canada, and 13 will be Super Triples headed for the United States.
In the broader group of 28 new rigs planned, 17 are contracted while the company has “firm commitments” for most of the other 11 rigs.
Higher spending on rig iron is under-pinned by Precision’s optimism about the near-term strength of the North American onshore drilling market.
Precision Drilling is building three new Super Singles like this one for its Canadian fleet, and 13 Super Triples that will go to work in the United States.
“We expect summer activity to look very good,” Kevin Neveu, Precision’s president and chief executive officer, told shareholders, adding that he expects this summer’s drilling season to be the busiest in several years.
“I am particularly pleased to see strong market demand for the Super Triple rig in the Bakken and Eagle Ford plays, with 13 of [the] announced new builds slated for those oil and natural gas liquids-rich plays,” he said.
South of the border, rig counts are near his-toric highs, with many producers targeting oil, he said. As recently as 2006, three-quarters of Precision’s drilling rigs were targeting natural gas, while just over half were pursuing gas in 2009. About 80 per cent of the company’s rigs drill horizontal or directional wells today.
This year’s capital spending, which includes $121 million for sustaining and infrastructure spending, is based on currently expected activity levels for 2011. Another
$458 million is slated for expansion capital for new-build rig programs.
This year’s total capital expenditures also include the cost of upgrading eight to 12 rigs and the purchase of long lead-time items for future rigs or upgrades at an expected cost of $211 million. Certain rig upgrades will depend upon the completion of term con-tracts before incurring planned spending.
Precision expects most of the $790 mil-lion total expenditures will go to its contract drilling division, while $72 million will be directed to its completion and production services division.
To complete its 2011 new-build rig program and the planned upgrades, Precision expects there will also be an additional $152 million of capital expenditures incurred in 2012.

Description of incident:➤ During a rig move, a truck and trailer unit was positioned to lift and
load a drilling rig pipe tub using a winch, cable and sling system.➤ After a swamper put the cable sling around the lifting points of
the pipe tub, the truck and trailer driver activated the winch and lifted the pipe tub onto the trailer.
➤ The pipe tub came into contact with a guide pin on the passen-ger side of the trailer. This indicated that the load and trailer were misaligned.
➤ It was then decided to lower the load back on the ground and to “walk the load over.” The practice of “walking the load over” aims at repositioning a misaligned load by shifting it a few centimetres in the desired direction.
➤ “Walking the load over” consists of unrolling the winch cable and sling to obtain some slack and then push or pull the slings over the live roll in a direction to reposition them. Pulling is done using hands and pushing may involve either hands or feet.
➤ Once the sling is repositioned, the winch is activated to take out the winch cable slack and a side pressure is applied on the sling using hands or feet. This will cause the sling to be positioned in the desired location on the trailer live roll.
➤ The shift in the sling position over the trailer live roll causes a slight shift of the load as it lifts off the ground.
➤ As the winch cable and sling tightened, the swamper quickly removed his right hand from the sling but his left hand was caught between the sling and the trailer live roll. The swamper’s left hand was crushed and the wrist sustained a fracture.
What Caused it:➤ A swamper was standing between the pipe tub and the back of the
trailer trying to re-position the sling. The worker was holding a section of the sling beneath the trailer live roll with his left hand.
The worker lifted his right arm and grabbed the upper section of the sling to help him pull more cable out of the winch.
➤ As the driver saw the swamper’s hand motion, he understood this to be an instruction to lift. The driver activated the winch to lift the load.
Corrective Actions:➤ Workers must always stay away from loads and lifting gear. The
practice of “walking the load over” is hazardous to the swamper.The following alternatives may be used in case of load misalignment:➤ The truck shall pull forward and manoeuvre, while reversing, so
that the trailer can be better aligned with the load. Workers shall use extended hooks to adjust the position of the sling on the live roll and apply needed pressure when the load begins lifting.
➤ During lifting operations, one competent person shall be clearly designated as a “signaler,” and workers involved in the job must be made aware. The signaler is to be the only person to direct the movement of equipment. The only signal that can be given by any other worker is the “STOP” signal when a situation arises.
➤ The signaler shall always wear high-visibility clothing for ease of identification.
➤ When an unplanned event occurs during a job, the team must stop the job to reassess the hazards and define a plan forward.
