$this->bbcode_second_pass_quote('', 'B')erman extracts his data from shale company's own SEC 10-K filings.

I seriously doubt that unless he is Houdini, 10 K reports reserves, production and financial information on a consolidated basis. It does not speak to individual well performance. That information would have been available to the third party auditors but it is not something you can access from SEC. I actually sat in a presentation that Berman made to the executive team at a company I worked at before retirement. His claim was the data came from state production data filled by companies.

In his study, only horizontal wells were evaluated. His methods are robust:Berman clearly shows that the impression of long tails from company data as you have presented are a consequence of both 'survivorship bias', the increasing influence on the average well production over time by the survival of fewer and better performing wells and refracting, re-stimulation that require additional capital investment. It is clear from the both data and the nature of fractured shale source material (there is no natural drive beyond that immediately surround the fractures structure) that hopes for long production are misplaced. Rather than a "long tail" of steady profitable production of years, these shales plays can be expected to display exponential (weak to moderate hyperbolic) declines into the ground.[/quote]

If you look at the plots I show they are both individual wells and type curves which are a fit to a number of individual wells. They are not grouped numbers of wells which Berman is showing. His arguement about the flat portion of the curve being due to survivorship doesn't hold water as far as this data is concerned. This is individual wells showing this type of decline. There is still a lot of argument about what the proper decline analysis is to use in calculating EUR. It is recognized that two stage exponential decline makes no sense in a rock mechanics/fluid flow concept but it is also realized that a strict application of hyperbolic decline in the latter stages can result in a tendency for infinite looking reserve profiles. That is why when using decline analysis a formula is used by which the hyperbolic portion of the curve can be truncated.

The sense check here is if Berman was correct then all the companies drilling for shale resources would not be seeing profits....but, funny they do. A simple look at Cheseapeake or EOG 10K (you can find financial information there) shows they are quite profitable. Companies would not be investing billions of dollars in this industry based on decline models if it was as doomed as you suggest based on Bermans analysis. Berman once stated that the Haynesville shale would never be economic and it not too long after that became the most prolific economic gas producer in the country. So he has been wrong at least once in a big way.

This Peak Oil stuff is all so cool; there are so many smart and thoughtful people that participate on this site I learn something from every post, a little bit from everybody, all the time. Thanks y'all.

For the last time, I promise, at the risk of being obnoxiously repetitive, I want my industry to tell the truth about tight oil and tight gas resources. I don't see any way around 80,000 stinkin' liquid shale wells either; Lord knows we're going to need everyone of them even if all 80,000 of the little darlings only make a half million barrels of oil per day. But the cost of developing that resource is going to be staggering. Mind boggling. From a financial standpoint but also from the standpoint of how many other resources it is going to drain from our way of life. I thought they use to grow corn and wheat in N. Dakota, now it seems all they want to grow is shale wells.

All this horse pucky about 50 billion barrels of recoverable reserves from the Bakken, of the giant Monterrey, the prolific Cline (BTW, what happen to all the beef in the Utica?), of surpassing Saudi production, of the US being able to tell the world to stick its oil, that is all BS. If you are the CEO of Shale R US and tell the American people that shale is a game changer, that peak oil production rate fears are ridiculous, I am embarrassed for you. How can we ever get the American public to trust the oil and gas industry unless they know the truth about the future, the best we can estimate anyway? We owe them the truth.

If I may, a perfect example of tight oil BS (thank you Rockdoc); gas to oil equivalents, one of my pet peevies:

Gary Swindell's SPE paper is very much worth reading and I urge everyone to do so. Thru October of 2012 Mr. Swindell studied many wells in the EFS and determined the average EUR of those wells studied based on decline curve methodology to be 206,800 BOE using, as Mr. Rockdoc says, a 20:1 gas to oil ratio formula. I think it probably takes 165-185,000 BO to pay a typical EFS well out, but that's a different story. Mr. Swindell is absolutely correct to use product value for gas to oil equivalents, IMO; the entire tight oil industry hangs by a thread on well economics and the ability to raise more capital to stay on the drilling treadmill. When it publishes EUR's in BOE it should do so in an honorable way, in a way that American's will understand. Dollar for dollar, apples to apples. In 2013, with LLS postings for shale oil above 100 dollars a barrel, the gas to oil ratio should actually now be about 30:1. If you produce a million a day of associated gas with your liquids that should equate to 33 BOEPD.

The shale industry however likes to use BTU equivalents for gas to oil conversions. That's historically 6:1. That's fudging the numbers to me, especially in N. Dakota where 75% of that gas gets burned off to the air and all them perrdy "BTU's" go up in smoke anyway. So, at 6:1 gas to oil equivalent rates a million a day of associated gas equates to 166 BOEPD. The Pinky Toe No. 14H, that makes 350 BOPD, now gets reported as 516 BOEPD in the press release. If you look hard that press release might say 74% of that is liquids, in real fine print, but whatzup with that? Why not just say the stinkin' well makes 350 BOPD and go to the house? Because bigger numbers means bigger EUR's, more booked reserves, the big cheese in the front office looks better...Wall Street likey and grandma likey so much she calls Merrill Lynch and buys more shares of Shale R Us.

$this->bbcode_second_pass_quote('rockdoc123', 'O')f course there is still the issue regarding sweet spots within the shales. The Swindell study addresses this for the Eagle Ford by looking at EUR on a county by county basis. Interestingly enough if you correct his BOE conversion calculation (he uses 20:1 as he believes it reflects price but the industry uses 6:1 as its standard unrelated to price) the EURs across the play are not all that much different, averaging out close to 400 MBOE/well.


Respectfully, Rockdoc, there is no "correction" to be made to Mr. Swindell's paper, IMO. I don't personally want to convert gas to oil your, or the shale industry's way. It does not give me the information I need to determine if this shale stuff is going to last 80,000 wells. I can dig out the right poop but most Americans won't. That kind of reporting BS is about as transparent to the American public as 9.8 drilling mud and an example of the lack of truth in tight oil advertising.

Thanks again, y'all. Its been fun.

The realization of the truth throughout the population will be a disaster since it will collapse consumer confidence and cause hoarding. Leading to massive joblosses and unrest. Which in turn leads to government intervention and oppression.

The global society today is like a horde of dominoes.. The truth will tip the first domino.

Right now we are barely keeping the skin on our noses and this is with massive propaganda. The useless consumption is unsteadily trotting along - with only "minor" hordes of unemployed and disgruntled workers.

As the surplus of nature and energy lessens we are increasingly living in a more fragile system with more pollution - none of these trends can be reversed without destroying the middle class and helping a lot of people to meet god ahead of schedule.

Perhaps you will use compartmentalization? I.e. destroy the consumption in other parts of the world and since the havoc is so far away and not seen as much its A-Okay?

Well first off Swindell is not correct to use that conversion for anything other than to look at a current snapshot of economic recoverable EUR. It is otherwise meaningless. And it is not just the shale industry , as you suggest, that uses the 6:1 conversion…it is a standard used by all oil companies in reporting to the SEC, OSC and it is employed by every large consulting firm I know about and by every financial banking firm that covers oil and gas. It is a standard so that you always know you can compare apples to apples. Why not use a price correction instead?…simply because price is always changing. A few years ago when natural gas was selling at $14/Mcf on the spot and oil was around $80/bbl you would have had to use a much lower conversion than 6:1 and Swindells EUR number would have been even higher than the 400 Mbbl that is present in the liquids richest part. You can be absolutely sure that in a few years time oil and gas prices will be different than they are now, hence a conversion based on price is pretty useless as a standard conversion. The Eagle Ford activity has shifted to the liquids richest part, many of the wells produce mostly oil with associated gas rather than gas with liquids. Using a different conversion factor muddies the waters here given the entire industry uses the 6:1 conversion. As a consequence someone who doesn’t understand what BOE really means and isn’t aware that Swindell is using a different conversion factor would wrongfully argue that….Oh look Cheseapeake is lying about their reserves because they say they have average EUR of around 500 MBoe and Swindell says it is only 200 MBoe when in reality given CHK is in the best part of the play (thicker and overpressured) when you use the standard conversion factor their numbers are almost identical to what Swindell came up with. The use of the 6:1 conversion has nothing to do with “bigger numbers” being published. If you bother to look at 10K’s from any company the production and reserves are reported both in barrels and MCF as well as BOE equivalent. In most press releases companies report using both BOE and bbl/MCF terminology. Here is an example from EOG which illustrates that:

$this->bbcode_second_pass_quote('', 'E')OG made strides in increasing the amount of crude oil recoverable from both its Eagle Ford and Bakken resources by testing various drilling densities and further refining completion practices. In the Eagle Ford, EOG increased the estimated recoverable potential reserves by 38 percent from 1.6 billion barrels of oil equivalent (BnBoe) to 2.2 BnBoe, net to EOG. Numerous spacing pilots across EOG's 569,000 net acres in the crude oil window point to optimal resource development on 40-acre well spacing in the east and 65 acres in the west. At current activity levels, EOG has a 12-year Eagle Ford drilling inventory.
The revised Eagle Ford reserve potential is indicative of an estimated 8 percent recovery of the estimated 26.4 net BnBoe in place on EOG's acreage. Since discovering the Eagle Ford in 2010, EOG has raised the overall estimated captured reserve potential from 900 MMBoe (million barrels of oil equivalent) to 2.2 BnBoe, net to EOG.
EOG's best Eagle Ford well to date is the Burrow Unit #2H, which had an initial production rate of 6,330 barrels of oil per day (Bopd) with 713 barrels per day (Bpd) of natural gas liquids (NGLs) and 4.1 million cubic feet per day (MMcfd) of natural gas. Offsetting the Burrow Unit #2H, the Burrow Unit #1H was completed to sales at a maximum rate of 5,424 Bopd with 600 Bpd of NGLs and 3.5 MMcfd of natural gas. Two other prolific wells, the Boothe Unit #1H and #2H, began initial production at 5,380 and 3,810 Bopd with 625 and 525 Bpd of NGLs and 3.6 and 3.0 MMcfd of natural gas, respectively. EOG has 100 percent working interest in these Gonzales County wells.
In McMullen County, southwest of EOG's Gonzales County sweet spot, the Naylor Jones Unit 59 East #1H and West #4H had initial peak production rates of 1,670 and 1,150 Bopd with 225 and 138 Bpd of NGLs and 1.3 and 0.8 MMcfd of natural gas, respectively. EOG has 100 percent working interest in these wells that were completed in early January 2013.

Exactly. Thank you.

The tight oil industry should go to great lengths to insure that Americans do understand what BOE means. It conveniently does not, in my mind. In Swindell's example you have DOUBLED the EUR's of a typical EFS shale wells in his study by a simple slight of hand in the gas to oil conversions. A typical American is going to look at your hypothetical CHK well with 500K BOE EUR and think, wow, that well is going make 50 million dollars gross in its lifetime when in reality it is actually going to be lucky to make half that money. You state that Mr. Swindell's study should be corrected and I think that is brazen of you, sir. In reality I have a far better grasp on the economics of a typical shale well he studied because of his conversion ratios and perhaps that was exactly his intent. That hardly makes him wrong and of need of being "corrected."

Show me the money!! Mr. Swindell showed me the money. That works plenty fine for me. And it does I bet for most Americans.

Look, I respect that you are an engineer very much... because I am not; I can only debate with you up to a point and then have to humbly withdraw. I know some about standardization in reserve reporting, SEC requirements and all that and you of course are correct. All I can tell you is that I graduated in the top 10 of my high school class (never mind there was only 16 of us altogether) and in an effort to defend the shale oil industry you are completely ignoring my point regarding truth in advertising.

Not all of us our engineers. I want Americans to be able to understand that they should indeed just about take everything the shale oil industry is spoon feeding them and divide it by half. Thanks for your help with that. The company you used as an example of submitting industry acceptable press releases, by the way, is the poster child for tight oil hoopla.

Oily - Just a small sidebar: did y'all touch on "equivalent how?" Obviously it depends: dollar equivalent (@ what ratio) - Btu equivalent - volume equivalent which only reservoir engineers would care about. And then it gets even sketchier if you think of the equivalent effect on a pubco's value: oil reserves could mean a different market valuation than an equivalent dollar value in NG reserves: a greater anticipation in the up/down movement in the price of oil/NG. I know folks who pay a higher price for a NG rich pubco now than one with mostly oil reserves.

Oily – Others have touched upon it. Some use a ratio of 6 mcf = 1 bbl of oil. Rather common in some quarters. What use is that: so 6 mcf at $4/mcf ($24) = 1 bbl at $90/bbl ($90). So $24 = $90? Anyone here want to swap my $24 for their $90? I didn’t think so. LOL.

So let’s make them equivalent on a monetary basis. So at $4/mcf one $90 bbl = 22.5 mcf. Great: so my 1,000,000 mcf of NG is equivalent to about 45k bo. OK but a couple of years ago when I was selling my NG for $2/mcf my I bcf was equal to only about 22k bo. But if NG goes to $6/mcf in a couple of years my 1 bcf is equal to 67k bo.

And what, pray tell, does all that crap mean? LOL. Now let’s look at the real world. Two pubco: one with all oil reserves and one with all NG reserves. Both have a current values of $500 million. All other metrics equal. So which one might you invest in? The one whose assets have had a constant value and which has seen the greatest increase in production rate in US history? Or the one who asset price has doubled in a couple of years and which looks to be on an upward trend? Both have the same “equivalent” value today, after all.

And now the obvious: when your grilling outside tomorrow and your propane bottle runs dry are you going to syphon some gasoline out of your car and toss it on the barbie? LOL. Or when your car runs dry are you to run a very long hose from your space heater to your gas tank?

Simply from the dictionary: Equivalent –

a. Equal, as in value, force, or meaning.
b. Having similar or identical effects.

So when is a volume of NG always going to be equal in value to a volume of oil? Never since their values will never be constant.

When can the force derived from burning NG always be equal to the force derived from burning oil? I can drive a car using NG or the product of refined oil so now do I have to determine the equivalence? In mpg?

When will mcf mean barrel?

When will a gaseous hydrocarbon have the same effect as a liquid hydrocarbon? When they are both used to create the same energy. So now we have to resort to thermodynamics and mechanical efficiency to come up with BOE?

IMHO “BOE” is one of the most misunderstood and misused terms in the oil patch. And thus one of the most useless. Especially since it’s often used without defining the basis for the equivalence even when that basis makes little sense.

How do I use BOE in my economic analysis? I don’t: I use the individual volumes and price values for the oil and NG involved in the project. Just as I’ve seen every other company do during my entire career. IMHO the BOE calculation was created just for its use in press releases from the pubcos. Every pubco wants the public to relate to them as an oil producer these days even if the company doesn’t produce 1 bbl of oil.


LLS VS. WTI VS. BRENT:

Actually the entire WTI/LLS/Brent pricing dynamic as a lot of folks confused…including the Rockman. Eventually you might assume when an extra 3 million bopd are making its way from Cushing to the Gulf Coast in the next couple of years the LLS/WTI spread will decrease. But right now from:

http://www.rbnenergy.com/are-they-never ... ther-again

“Before LLS suddenly moved higher than Brent in the past two weeks, analysts generally believed that the WTI discount to LLS would narrow as and when the WTI discount to Brent did. In fact as the WTI discount to Brent narrowed this month the WTI discount to LLS hardly moved. LLS is therefore showing unexpected strength right now. As new supplies of light sweet crude from US domestic production in the Bakken, Eagle Ford and Permian basin begin to arrive at the Gulf Coast, the WTI discount to LLS was expected to narrow because these new supplies would compete with LLS and push out higher priced light sweet crude imports. The fact that LLS prices have strengthened suggests that either the volume of new domestic crude attracted to the Gulf Coast is not yet sufficient to compete with LLS or that quality issues with the new light crudes are impacting their price versus LLS.”

The spread shows LLS trading at almost $8/bbl and appears to be increasing with WTI decreasing its difference to Brent by the same amount. Some speculation that the feds may do another SPR release to nock some of the wind out of the LLS. They did that a while ago but only worked briefly.

And in my economic analysis neither do I, Rockman. When and if I sell a deal, I am going to be honest and upfront about every component of it, right down to how much pipe dope we might have to use in a pipe trip. Why? Its not because I can get away with SEC stuff, or that's the industry standards; its not because everyone else does it. Its because telling the truth is the right thing to do. I'd rather live under a bridge in a cardboard box than not be honest with people and have them disappointed in a deal I sold them. They likely will be anyway, that's the oil business, but it will not because I sold them a bill of goods. So from me you will hear the upside, but then we will focus on the downside.

If you BS people, you don't get to stay in the oil and gas business. You and I have been doing this a long time for one reason and one reason only.

So people will trust us. So we can sleep at night.

Goodnight.

Re: What is the Point?

Unread postby rockdoc123 » Mon 27 May 2013, 12:48:19

let me clarify with respect to BOE and how it is used in reporting by oil and gas companies:
Back in 2001 the SPE first pass at the resource/reserves definitions stated:

$this->bbcode_second_pass_quote('', 'C')onverting gas volumes to the oil equivalent is customarily done on the basis of the heating content or calorific value of the fuel. There are a number of methodologies in common use.
Before aggregating, the gas volumes first must be converted to the same temperature and pressure.
Common industry gas conversion factors usually range between 1 barrel of oil equivalent (boe) = 5.8 thousand standard cubic feet of gas (mscf) to 1 boe = 6.0 mscf.


Currently the directions as outlined here by the TSX.v with regard to National Instrument 51-101 for reserve reporting are:

$this->bbcode_second_pass_quote('', 'I')f disclosure is made in BOEs, using a gas to oil conversion ratio, Section 5.14 of NI 51-101 currently requires that RIs do the conversion using a ratio of six thousand cubic feet (Mcf) to one barrel (bbl) of oil. Section 5.14 also prescribes the use of a cautionary statement as follows:
“BOEs [or ‘McfGEs’ or other applicable units of equivalency] may be misleading, particularly if used in isolation. A BOE conversion ratio of 6 Mcf: 1 bbl [or ‘An McfGE conversion ratio of 1 bbl: 6 Mcf’] is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead.”


As a consequence you find such statements in various press releases by oil and gas companies:
Here is an example from TAG oil out of a 5K submission to the SEC:

$this->bbcode_second_pass_quote('', 'C')ertain natural gas volumes have been converted to boe on the basis of six Mcf to one bbl. Disclosure provided herein in respect of boe may be misleading, particularly if used in isolation. A boe conversion ratio of 6 Mcf: 1 bbl is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead. Given that the value ratio based on the current price of crude oil as compared to natural gas is significantly different from the energy equivalency of 6:1, utilizing a conversion on a 6:1 basis may be misleading as an indication of value.


One from PetroBakken to the TSX:
$this->bbcode_second_pass_quote('', 'B')OE’s (or ‘McfGE’s’ or other applicable units of equivalency) may be misleading, particularly if used in isolation. A BOE conversion ratio of 6 Mcf:1bbl (or ‘An McfGE conversion ratio of 1 bbl:6 Mcf’) is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead.


Yes you can actually calculate BOE on several basis (heating value, wellhead price, market value or take what was used many years ago as a 10:1 ratio) but you must report by heating value conversion to either the SEC, TSX and the internal revenue service. As a consequence a public company cannot issue press releases that aren't SEC/TSX compliant. In Canada almost all companies use the disclosure statement in their press releases, in the US it isn't universal simply because they state they are compliant with the SEC requirements and have made the statement regarding BOE conversion in their 10K, 6K etc.
So when you see a press release from a company using BOE they are using the 6:1 conversion ration unless they specify that they have done something different for a particular reason (for example they might have wanted to be more accurate with respect to energy equivalent conversion based on actual BTU heat content of their liquid fraction) in which case they will make it very clear what conversion they have used and why and will also have reported the actual bbls and mcf reserves separately (otherwise the SEC would be down their throats).
