Idle Rambling On The Bakken, My Second Favorite Subject -- October 3, 2019

I'm going through every well that was permitted / drilled / completed back in the 2008 time period, by permit, the 16XXX series. I do this periodically, from time to time, take a specific series of permits and go through them. For example, I am doing the 16XXX series this week; maybe next week I will do the 17XXX series. And so on.

I literally go through every well -- it will take several days. But it is really amazing. Sure, there are a lot of wells that have not done particularly well, but they are still in production. But in general, I find it amazing how many wells show a jump in production, again for any number of reasons.

As I go through the list -- remember, these are the 16XXX wells -- one thousand of them -- 99% of them Bakken --and "we" have just begun the 37XXX series wells (October, 2019) -- that's (37000 - 16000 = 21,000 Bakken wells). I was saying: as I go through the list, the 16XXX wells drilled back in 2008 or thereabouts, all I see are scores (or hundreds) of wells that need to be re-fracked. It is absolutely amazing.

The problem for the operators is not whether to drill or not, whether to re-frack or not, the problem is what to prioritize? The operators are simply limited by resources: money, people, time, etc. I'm convinced Harold Hamm thinks about this 24/7.

I don't think anyone has any idea how much work needs to be done in the Bakken, just with the wells that are already drilled. It is simply amazing.

Here's another one.

Jack Pennington,  #16778.

16778, 354, MRO, Jack Pennington 21-28H, Reunion Bay, t8/08; cum 567K 10/19; off line 10/19; remains off line 4/20;

Test date: back on August 14, 2008. An IP of 354 in Reunion Bay. Ridiculous. Piss-poor as they say. Today, one would expect the IP in a Reunion Bay well to be 2,000 to 3,000. Maybe more.

This well's initial production in 2008 was pretty unremarkable, maybe even lousy: see the first six months of production below. If this well cost $10 million to drill / complete at the time, and at $50/bbl, this well produced 25,000 bbls x $50 = $1.25 million in the first six months. Not very good. In fact, lousy. A lot of folks would have called it "uneconomic."

Ten million dollars to drill/complete and only a million dollars to show for it after six months. (These days, these same wells might pay for themselves in the first six months). First six months production for this wells back in late 2008. The best it ever did at that time, a lousy 6,000 bbls/month.

BAKKEN8-200827609258282573266802668

By 2014, six years later, this well had declined to 1,400 bbls/month -- the dreaded Bakken decline rate:

BAKKEN3-201431129112542181165479363

If a conventional well, it was likely ready to be abandoned, at worse; or, at best, sold as a stripper well. A stripper well: 10 - 15 bbls/day.

But then look what happened in August, 2014:

BAKKEN8-201419129941295843901151134646519

Just like that, magic! In those nine months: 130,464 bbls of oil produced. At $50/bbl, $6.5 million in less than a year. And that doesn't include natural gas, etc.

Then, by August, 2016, it was back down to 5,000 bbls/month -- very, very respectable, and no one was complaining, but then look what happened in May, 2017. Another jump. More magic:

BAKKEN12-20162844864532136661495040467

Another 83,000 bbls in eight months, between May, 2017, and the end of the year (2017).

The well is still producing a very, very respectable 4,000 bbls/month, and my hunch is that we will see another jump in production in the next couple of years.

And I can find example after example after example of these wells. Absolutely amazing. Something I don't think we see in conventional wells and something no one seems to be talking about even when it's staring them in the face here in the Bakken.

Remember: Hubbert's theory applies to individual wells as well as fields and basins. 

Disclaimer: I am inappropriately exuberant about the Bakken. I may see things that don't exist. I will make typographical and factual errors. If this is important to you, go to the source.

Another One

These are not hard wells to find. They simply keep popping up

I could have used MRO's Bill Connolly 21-25H well as an example also, but I think I've discussed it a couple of times already.

But it's another great example.

Completed back in early 2008; a pretty average well for that time period:
