Whose wells produce best?

I have looked around a bit and haven't seen much related to this question. Forgive me if I missed something.

Of course a lot of factors affect productivity at each well, but how much does the lease holder effect that? I mean, all things being equal, do some companies' wells produce more on average than their competitors? Common sense says that a company with a lot of resources like Shell will have more money to invest in talent, data gathering, contractors, etc. than a smaller company like, say, Chief. But does anyone know if that's true in practice?

that's a good question...hope someone with some knowledge about that will answer your post soon.  btw...how did you get a gomarcellusshale name like 'mud'?  surely there is a story there also. Imagine...'how's mud doing today?" also btw...welcome to gomarcellusshale 'mud'. (just having some fun)

Thanks VG. Mud?...That was my moonshiner handle and I just like it. haha

I appreciate that, Homer. It was late and I didn't word the question very well. It should have read something more like: If 2 companies each had the same location and they each did their thing how would their respective yields from that unit stack up? Will Shell (or SWN, or CHK) on average produce the most gas possible from a given unit?

There was a stray comment in the forum here about smaller drillers being less efficient and leaving more gas in the ground. it makes sense that some would be better at what they do. But is there evidence or is impossible to compare? Largely it doesn't matter since landowners don't choose who drills anyway. Just curious.

I understand the basics of the technique and appreciate your help. But what I'm asking isn't a technical question. I'm asking if some of the companies are better at their task.

You are a petroleum engineer, right? Surely you've seen the discrepancy between what you design and what actually happens at times. I've seen it in my line of work lots. :) 

 

Seems like one would have to crunch the production numbers to see a trend of some sort. I'd be willing but am unsure how.

the question really is this:

What company is able to recover the most oil/gas from a well?

Say CHK   is at 5%

SAY XTO is at 6%

As a landowner, all this being equal, we would want the driller that is

more efficient in the extraction to be the operator of the well(s) drilled in our drilling unit.....giving us the most royalties.

Yes. Thank you, sir.

The PA DEP website has well production data available. It would be easy enough to find a simple daily or monthly average production per well per company and graph it but the age of the well is going to have to be compensated for. That's going to be tricky considering the rapid decline in the first 2 years. 

 

Once it's done (if it gets done-I have 3 young kids, a beautiful wife and a full time job) I'll post up the results and how I got them for critique.

Hmmm...Any idea what a more accurate rate would be? I can search around, too. That sort of info might be on the forum already.

Right now, it's not estimation it is guesstimation.

Assume the worst possible decline curve, and hope that you will be pleasantly surprised.

The answer to our questions/concerns will only be evident at some indeterminate time in the future - as we look in the rear view mirror.

To complicate matters, techniques and technology are evolving as I type.

Right now, a fortune teller might be our best bet, as they peer into their crystal ball.

 

All in my humble opinion.

One size fits a few.

I believe the thickness of the shale  has something to do with how long it will produce?

Thickness of the shale will be one of many factors that will determine longevity of production.

I only have one word in response to "one of the first wells I did over 2 1/2 yrs ago has remained at a constant 2.5 to 3 million a day for over two years"

WOW!
