Before publishing the article The Most Prolific Oil Well in Alberta, I asked many friends in the industry if they could guess the size (in terms of cumulative oil production) of the largest oil well in Alberta. I heard estimates as low as 3 and as high as 10 million barrels. Many were shocked to hear that 100/09-22-051-27W4 has produced 39.7 million barrels. This brought up another interesting question, how many other wells produced 10 million barrels or more?
To date, there are 41 wells that have produced more than 10 million barrels of oil in Alberta. Close to half of the wells on the list are Leduc wells from Central Alberta. In fact, 9 of the top 10 wells are Leduc (D-3) wells. The other formations on the list are: Keg River, Nisku and Swan Hills.
Geologists and reservoir engineers may note that these are all Devonian aged carbonate reefs with active water drives and high pool recoveries (Leduc has a recovery factor of 64% [1]). While these reservoirs are world class, the major operators of the day deserve credit for creating optimized depletion plans and implementing enhanced oil recovery (EOR) schemes, such as miscible floods. These high recoveries are unlikely to have been achieved had proper reservoir management not been a priority.
All 41 wells can be viewed by clicking on this Petro Ninja Maps list and a summary table for the top 15 wells can be found below.
Oil production from the top 10 wells from 1962 onward can be viewed in the interactive chart below. Compare wells by clicking on the well LSD in the legend to show/hide data.
The discovery of Leduc oil in 1947 was the start of the conventional oil boom and you can see in the table above that most of the prolific Canadian oil wells were drilled within the two decades that followed. The Rainbow Lake discovery well 102/03-10-109-08W6/00 was drilled in 1965 and depending on who you talk to, it could be considered to be the last great conventional oil discovery in Alberta.
That said, with our rich reserves of unconventional oil in the form of oil sands and shale, there’s still a lot to get excited about. While we may never see a vertical well as prolific as 100/09-22-051-27W4 again, there are still conventional opportunities on a smaller scale. Look no further than Whitecap’s Elnora field, which was discovered in 2011.
In less than 4 years, one of the deviated wells in the pool, 102/15-17-035-22W4, has produced more than 800,000 barrels and is still producing at a rate of 1,400 bbl/d. No long horizontal leg required, no multi-stage fracture treatment, just 3 meters of perforations. Surely, this can’t be the only conventional pool that was missed in the 1950s and 1960s!
A valid question might be how many wells drilled in the 70s,80s, and 90s are on track to reach 10 million barrels? Yes, there will be other conventional wells to join the 10 million barrels club, but not many. Production from oil wells declines exponentially or hyperbolically, with the bulk of their production volume recovered in the early years. 100/09-22-051-27W4 produced 10 million barrels between 1949 and 1965 and it was under production rate control.
After the rate control was lifted, it produced another 10 million barrels in the 3 years between 1965 and 1968! Most of the wells in the 10 million barrels club produced the bulk of their production within the first 20 years. The wells in this club do not owe their membership due to their longer time frame to produce. There are 13 conventional wells that have produced between 9 and 10 million barrels, and only 100/10-29-67-10W5 is still active.
If we neglect its decline rate, and assume it maintains a rate of approximately 70bbl/d, it would be able to join the club in about 10 years. Admittance to the 10 million barrels club is no easy feat.

And the best thing about sucking up all that Alberta cancer juice is it all came consequence free right?
Warmer planet = more evaporation = more moisture in atmosphere = AGW jacked rain bombs and flooding.
Province boosts cost of Alberta floods to $6 billion
“Major areas of flood-related spending for the province so far include compensation for homeowners moved from floodways, business support programs and property tax relief for affected municipalities.
But the largest component of the province’s spending is its disaster relief program — which makes direct payments to individuals, organizations and small businesses for uninsured losses. A significant portion of those expenditures will ultimately be reimbursed by the federal government and Alberta has already asked for a $500-million advance from Ottawa.”

Fort McMurray wildfire costliest insured disaster in Canadian history
Insurance Bureau of Canada estimates fire in Alberta city in May will cost insurers about $3.58B
“The massive Fort McMurray, Alta., wildfire that forced more than 80,000 people from their homes in May is the costliest disaster for insurers in Canadian history.”
“In all, about 2,400 homes and buildings burned in the fire, which breached city limits on May 3 and torched entire neighbourhoods in the oilsands community.
Hundreds of buildings spared from the flames were left heavily damaged or even uninhabitable from smoke damage.”
http://www.cbc.ca/news/canada/edmonton/fort-mcmurray-wildfire-costliest-insured-disaster-in-canadian-history-at-nearly-3-6b-1.3668602
3.6 billion is just the insurance. There are many more costs. Hell the donation money alone came to $300 million.
Now here is a perfect example of Denial Canadian style. Canadian style is lots of fines and punishment. Canda likes rules and punishment and scapegoats.
Fines of up to $1 million included in proposed wildfire bill
http://www.fortmcmurraytoday.com/2016/10/31/fines-of-up-to-1-million-included-in-proposed-wildfire-bill
Since the spark/ignition for the fire was deemed to come from a human and not lighting it provides them with a perfect opportunity to scapegoat individuals now and in the future and ignore the fact that fire season is over 2 months longer than in the 1980’s and everything is dried out, even in winter. What we have here is legislated denial. See? Canadian cancer monkeys are just as much in denial as merican redneck conservatives – they just go about it in their own cultural fashion. Humans.

BTW, that fire is still burning.
The Beast is alive: How the fire that tried to destroy Fort McMurray is still burning near the Saskatchewan border
http://news.nationalpost.com/news/canada/the-beast-is-alive-how-the-fire-that-tried-to-destroy-fort-mcmurray-is-still-burning-near-the-albertasaskatchewan-border
Here’s what the science really says about Fort McMurray and climate change
“In terms of the total areas destroyed by fires, there’s an unmistakable escalation, they say.”
“As temperatures warm, they say, the likelihood is greater that more out of control infernos will consume more trees and human infrastructure.
“Climate change is here,” Flannigan says. “And we’re seeing more fires and arguably more intense fires because of it. Our area burned in Canada has doubled since the seventies. I, and others, say that this increase in area burned is related to temperature, which is related to human caused climate change.”
“Government assessment shows increased forest fire activity in last 40 years”
“It was so powerful it created its own weather, fierce and powerful winds and lightning emerged from the monster-sized blaze.
Flannigan has seen cases where forest fires generated their own thunderstorms, but he’s never heard about a fire generating its own lightning that sparked a new blaze to grow and spread. That’s a first, and he knows what he’s talking about.
The prolific researcher has degrees in physics, atmospheric science and plant sciences, and he has published more than 100 research papers in peer-reviewed journals, including 30 papers related to forests and climate change.”
http://www.nationalobserver.com/2016/06/03/analysis/heres-what-science-really-says-about-fort-mcmurray-and-climate-change
So what Canada has done in regards to “fighting” climate change is basically fuck all. Lip service and meaningless carbon tax that does nothing to slow the cancer. Plenty of pretend feel good shit though. Like the US and pretty much everywhere else there are many new fossil fuel projects in the works here. Canadian cancer monkey’s want more. That’s the priority. Is it any Wonder that I don’t hold out any hope for the humans?

“…there are still conventional opportunities on a smaller scale. Look no further than Whitecap’s Elnora field, which was discovered in 2011.”
First, I don’t recall anyone saying there weren’t many thousands of wells left to drill in conventional reservoirs. And perhaps some relatively rare big one but typically much, much smaller the ones he goes on endlessly about. And that big Whitecap discovery? Apparently not big enough for even the company to individually brag about on its website. Though it claims this field is one of the largest to be discovered in the trend for the last 20 years it doesn’t give reserve estimate.
The entire company’s reserve base of its 12 field and not just the Elnora Field: “Recently increased total proved reserves to 155 million bbls.”

Climate Change will impact all of us and future generations.
It is time to reduce fossil fuel use and transition to safer, cleaner and cheaper alternative energy sources.
