BTU Factor and gallons NGL per Mcf

Can someone explain the conversion of  gallons NGL/Mcf into a BTU factor?  Or estimate a BTU factor from gallons/Mcf?  What's the math?   I can estimate the ethane/propane/iso butane/normal butane and natural gasoline percentages in a barrel if required.   Thanks.

Blu,

Back in January I left a comment on an article written by Rick Smead on RBN asking if RBN provided help with auditing the O&G companies relative to oil and gas royalties and deductions.  Rick is the Managing Director, Advisory Service, RBN Energy LLC.  Rick wrote me back privately (email) and told me that he had spoken with Rusty about my request.  Rusty said that RBN itself does not provide such a service but that "we" probably know some folks who do.  I have not heard anything back from Rick or Rusty but I'm sure that if I bug them I could get some information.

While I'm in a production unit here in Butler County, PA, my O&G company XTO just started up production in June 2013 so I'm sort of waiting for some of the big corporate landowners to start getting checks before I try to rally the troops relative to auditing.

Phil,

 I lived for a year in Gibsonia, PA. But I'm in a GPOR drilling unit in Belmont Cty, Ohio where fracking is just commencing on three wells. Our property is located between several extraordinarily large wells. Very exciting!

  I'm hoping I will not have a need for someone to audit royalty payments. Probably naive thinking.

Blu,

I live north of Gibsonia but my business was there for 37 years.

Gulfport has been hitting some big wells out there.  I'd be excited too!!  Good luck!

The royalty is determent by selling prices and deductions none of which are (currently) transparent transactions.  Even the most well meaning O&G company could make a mistake.  The landowner and the O&G company have a contract, I believe that the O&G company owes the landowner complete transparency.  Many leases even have an audit clause.  Nobody's lease says "we are not going to tell you how the prices and deductions are determined".  Since the lease is a contract, I believe you have the right to audit even without an audit clause.

Blueflame: catchy name we had a meeting room called Blueflame Hall. The gas that goes into the transmission line is what is refered  to as pipeline quality gas. Reinjection of ethane will increase BTUS. Most contracts to transmission lines will call for no more than 1100 BTS, less then 7 # per million of moisture, less than 4 parts per million of H2S. However gathering lines or not under the same regulations as interstate transmission pipelines. These numbers can be slightly different from co. to co. Methane will be about 88%

D.S.,

 In a posting a few months ago, "Bluflame" was associated with a superhero. My wife quickly quelched that thought!

I'd like to see a picture of a "pig launcher" so I'll know what to look for.  I was told by Markwest that they ran pigs twice a day in the lines to keep the liquids moving.

When Antero put in their gathering lines, one of them was ~22" black plastic and one was steel.  Maybe the plastic one is for the corrosive "wet" stuff?  What would the other be for?   Both were laid in the same ROW.

Pig launcher. More avail if you different perspectives.

Hiker,

The plastic pipe might be for fracking water.  All of the pipes I have seen here are steel.  Welded normally.  The corrosive moniker may have applied to older material or perhaps gas with some other impurities like sulfur.  These local modern pipes in this area carry C1 thru C12.

I'll get you a pig launcher picture.

In the mean time see PIG Launchers

Thanks Invictus.  Great pics, especially the third one showing the connection that would be underground.

Can some one post a picture of the actual "pig" and give some explanation of the process?   I am assuming the wetter the gas the more frequently the pigging operation needs to occur.   Also doesn't the steep terrain in much of the Marcellus/Utica area make the pigging operation more necessary and is there a temperature factor making the pigging operation more necessary in cold weather?

Searcher,

Click on PIG Launchers in my post above.  You will see lots of pigs.

lol, I did, but I am mechanically challenged and I wasn't sure if they were all the same size shape, etc.
