Random Look At An Interesting Well In A Most Interesting Oil Field In The Bakken -- February 21, 2017

Disclaimer: this was the last thing I did before turning in for the night. There may be all kinds of mistakes in this post. Tomorrow morning I may regret having posted it, but for now I will take the chance. We'll sort it out later. 

Disclaimer: in a long note like this there will be typographic and factual errors. After spending a lot of time on this, I hope I didn't make a really simple mistake. But I probably did. If I did, I will find it tomorrow. Whatever. I may be seeing things that don't exist. I am inappropriately exuberant about the Bakken. I guess this is for my own use. Don't quote me on any of this. If this is important to you, go to the source.

Comment: for newbies, I think this well teaches us a lot about the Bakken. It's the kind of stuff analysts on Wall Street in NYC really don't have time for. 

Another comment: This is another one of those posts where I assume landmen and roughnecks will laugh at me. That's fine.

But I'm like a kid in a candy store when it comes to the Bakken. The Bakken never ceases to amaze me and I never get tired of looking at it or blogging about it. I do hit a wall once in awhile, but the "bad periods" only last a few days at most.

Again, for newbies, I have no background or training or experience in oil exploration and production. Nada. Nil. Zilch. I probably understand 3% of what I read about the Bakken.  But I've been blogging about the Bakken since 2007 and it never gets old.

I think operators are still learning about the Bakken. I think there are a lot of surprises left.

What is Love, A Night at The Roxbury
*********************************
So, let's get started.

Earlier tonight I was looking at a well with this production profile over the last few months:

BAKKEN8-20160000000
BAKKEN7-20160000000

The full profile is here.

For one to really understand the post, it's important to look at the full profile.

The full profile is here. (All three links take you to the same "full profile" -- but I'm serious -- you have to spend some time with the "full profile" of this well), the index well:
  • 17400, 546, Petro-Hunt, Sherven Trust 27B-2-4H, Charlson, t3/09; cum 265K 12/16; about 1 million lbs first frack; second frack and second IP later.
Okay, so you've looked at the full profile.

I did not stumble upon this well by accident. There is a method to my madness. Be that as it may.

This is an important well. It tells us much about the future of the Bakken. It brings up many, many questions. And provides a bit of insight regarding the Bakken and a bit of insight regarding unconventional plays.

I don't understand the specifics, but the short story appears to be this:

This well was originally drilled as a middle Bakken well back in 2009. For a 2009 well, it was not bad, with an IP of 546 bbls of oil and an early production profile that looked like this:

BAKKEN6-20093066236580521837608166
BAKKEN5-20093186868668705107146049893

BAKKEN9-20080000000
BAKKEN8-20080000000
BAKKEN7-20080000000
BAKKEN6-20080000000
BAKKEN5-20080000000
BAKKEN4-20080000000

Once fracked, its first month of production was a pretty decent (for that time period) 13,416 bbls/month and then the typical dreaded Bakken decline, down to less than 9,000 bbls the very next month.

Then something happened. Maybe it was being re-worked, who knows, I couldn't interpret the report, but landmen and roughnecks will understand it, but the bottom line is this: the production profile looked like this:

BAKKEN5-20160000000
BAKKEN4-20160000000
BAKKEN3-20160000000
BAKKEN2-20160000000
BAKKEN1-20160000700
BAKKEN12-20150000000
BAKKEN11-20150000000
BAKKEN10-20150000000
BAKKEN9-20150000000
BAKKEN8-20150000000
BAKKEN7-20150000000
BAKKEN6-20150000000
BAKKEN5-20150000000
BAKKEN4-20150000000
BAKKEN3-20150000000

Even if you have no background in oil exploration, I think the data above is pretty clear cut. The hint: all the zeros. For newbies, this tells us that from March, 2015, to May, 2016, this well was shut-in, not producing a thing. If this was Apollo 13, this was the "Houston, we have a problem" moment.

Again, I don't understand the lingo, so I don't know the specific cause, but suffice it to say, somehow the well was screwed up.

But this is the Charlson field and Petro-Hunt had the lease and didn't want to lose a good well. The Charlson is a very, very good field. (Teague first identified the Charlson as a great Bakken oil field, and I owe him a lot for pointing that out.)

Petro-Hunt had a gazillion options, but it appears it came down to two options: 
a) re-drill the well, drilling a new lateral and targeting the same formation, the middle Bakken; or,
b) re-drill the well, drilling lower, and targeting the Three Forks.
They chose the latter.

But you know, you know what's really cool? They didn't do the simple thing, the obvious thing. They didn't target the first bench of the Three Forks; they targeted the second bench of the Three Forks.

So, now look at the events:

First, the index well, #17400, first drilled as a middle Bakken, initial production, after that frack back in 2009:

BAKKEN5-20093186868668705107146049893
BAKKEN4-2009301241612334130015568407611282
BAKKEN3-20098331030591390162714100

Then, the dreaded Bakken decline (see full profile, linked above) until March, 2014, when production for one month surged to almost 20,000 bbls from only 6,000 bbls the month before (and it was off-line for two days):

BAKKEN2-201426566855742551735220035168

What could explain the jump from 6,000 bbls to 20,000 bbls in one month? I have no idea. LOL.

But it is interesting that a neighboring well was fracked just prior to that surge:

See the graphic below to note where #26205 is in relationship to the index well.

So, we have an index well that jumps in production from 6,000 bbls to 20,000 bbls month-over-month with no obvious explanation but a neighboring well was fracked at just that time.

Sherlock had a way to explain this. 
Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth.
****************************

Stick with me. It gets more complicated. Or at least more interesting.

Note that another neighboring well was fracked in February, 2015 (#27375) (see graphic below). One might expect something similar. But the index well was shut-in at that time, so we will never how interesting it might have been.

******************************

Fast forward to 2016. Petro-Hunt has this really cool well in a really cool field, the Charlson, but the well is messed up. Something screwed up the well. Petro-Hunt had a gazillion options, as noted above, but decided to re-drill the well and target the second bench of the Three Forks.

I find that really gutsy; really cool. Re-drilling the middle Bakken with a new lateral would have guaranteed another good well, but Petro-Hunt decided to test the second bench of the Three Forks.

Perhaps it was just something the CEO wanted to do, or perhaps the geologists saw stuff from the original work and were curious what the second bench might do. So, the re-drill targeting the second bench of the Three Forks got them this:

This is the full production profile for Petro-Hunt well #17400. It is to be used in conjunction with another post. I placed the full production profile in this eparate post because the linked post was getting way too long.
