Bull Moose 1X-15: A Vertical Well Producing Since 1981 -- 556,000 Bbls of Oil and Still Counting -- Bull Moose 23-43X -- 1.3 Million Bbls -- North Dakota,USA

In yesterday's daily activity report, the following permit was noted:

• 21290, 1,068, BR, Red Wing 16-1H, Wildcat, t5/12; cum 12K 12/12;

It's unimportant why I was curious about this well, but something about it piqued my interest. I found the location on the NDIC GIS map server, though it has not yet been placed there on the map.

This Burlington Resources permit is out in the middle of nowhere. When I see that, it's always interesting to find the nearest well and see if there is any information that might be interesting to others.

In this case, Bull Moose 1X-15 (#7944), a conventional, vertical well, spud in 1981, is located one mile to the east from that new BR permitted location.

Bull Moose was spudded in 1980, and the Red River formation was targeted and tested. The IP was 437 and it turned out to be a good well, but finally petered out in 1999. The well was shut in from 1999 to 2002 when it was re-entered/re-spud. This time the target was the Madison, with an IP of 32.

How has the well done?

• From the Red River, that well produced 501,902 bbls of oil (now PNA).
• From the Madison, the well has produced 68,406 bbls (through December, 2012) and is still pumping about 300 bbls/month. 
• Note: when they re-entered the Madison in 2002, they also tested the Birdbear, but that was DRY.

Again, just an exciting story in the North Dakota oil patch. This well has been producing since 1981 -- 30 years and is still pumping. Of course, the original formation was shut in back in 1999. It should be noted that the well was still pumping around 1,500 bbls/month from the Red River when it was shut in.

One understands why folks are talking about Red River and Madison EOR.

I swear on a stack of Bibles that I did not check this out ahead of time. I was truly curious about the wells noted above, and then just for the fun of it, thought I would look at one more well (and I might look at a couple more) in the same little field, the Bull Moose field.

One-half mile south of #7944, Bull Moose 1X-15 is:

• 6718, Bull Moose 22-32F

This well has the following history:

• Madison, spud/tested 3/30/1979 with an IP of 123
• Red River, spud/tested 3/10/1981 with an IP of 486
• Birdbear, spud/tested 4/25/2000 with an IP of 200

So, how has this well done?

• From the Madison: 43,000 bbls
• From the Red River: 1.3 million bbls (yup, million)
• From the Birdbear: 136,000 bbls

It is now producing from the Birdbear, but it was still producing 1,200 bbls from the Madison, when they switched to the Red River. The Red River was still producing about 400 bbls when they switched to the Birdbear.

From the Birdbear, on a pump, starting in the year, 2000, it pumped 136,000 bbls of oil until 2008. The well has not been abandoned.

It looks like Sequel Energy, LLC, is going to see if there is some life still left in this old little field.

• 19765, 55/19, Sequel, Bull Moose 22Y-32, Bull Moose field, Duperow/Red River; t9/11 and t10/11; cum 5K 12/12; and 290 bbls 12/12; (no typo)

The Winnepeg pool is as deep as you go in the Williston Basin. The Winnipeg formation is below the Red River formation, the deepest formation, as far as I know.
