"... CONSOL Energy's Gas Division produced a record 40.4 Bcf for the quarter, or nearly 13% more than the 35.8 Bcf produced in the year-earlier quarter. The Gas Division also achieved peak production of 39.4 MMcf per day from the first five wells on a new 10-well pad in the Marcellus Shale ..."
The "choked down" average Cubic Feet per Day over a 12 month period will be much lower than PEAK. So maybe, these 5 choked wells would pay for the initial costs and "Break-Even" in 3 years (+/-). And in those first 3 years the well might release only 20% of the total gases?
Possibly, a profitable well assuming just Dry Nat Gas?
Wet Gas and Oil are a bonus!
You ask a good question. Just guessing I think your asking how do they bend bend the steel pipe used .
Steel and a lot of other materials have a property of what is called tinsel strength ductility Malleability and tensile strength. For a example steel can be hardened to a point to where it becomes hard like glass and can shatter, example tool steel. Steel can also be somewhat soft as well a example plain old black iron gas pipe used in home plumbing.
Tool steel if you try to bend it it will shatter but if you take a 10' section of say 1/2 black iron pipe and try to use it as a pry bar it will bend.
The radius of the bend is what allows the horizontal well to use this relative softness of the metal used.
Here is a list of videos that might help. https://www.google.com/search?rlz=1C1GPEA_enUS464US464&sugexp=c...
Yes it was about the 'bend'. You answered my question - the mechanical properties of the material.
It's just AMAZING...and I believe only the beginning.
You can actually see the drill pipe bend / arch when they are racking the pipe on a triple rig. A Triple Rig can pull "trip" three sections of pipe ( about 100' ) out at one time and rack them. The pipe is way more flexible than I ever expected, especially when three sections are connected together. There is no problem getting 700' or more of pipe to go around a gentle arch from vertical to horizontal.
Utica - The triple rig must be of the tallest we see? How tall? The largest I have seen were in Washington County in summer 2010 near Hickory and in Bradford County this April. And then I have seen a rig about 20-30' drilling a conventional well in McKean County. What a difference the shale play makes! -deb
The drill pipe and/or casing/liner has threaded connections, which also flex to be able to turn corners. The boreholes are intentionally drilled with smooth curvatures, and any " dog legs" are reamed out to ensure smooth passage of the drill pipe/casing/liner. Some liner systems can be rotated to aid in passage through tight spots, and the drilling fluid systems are often engineered to reduce friction to allow smooth passage of steel. It is not uncommon to perform "wiper" or short trips to simulate running conditions for steel pipe; and there are many computer models available to assist in the design, installation, and life cycles of the steel, includind frac stress, depletion stress, etc. I've experienced instances where stuck drill pipe was cemented in place to become the production liner. There are loads of clever people in the business whose days revolve around issues like you've described.
Brian - This is REALLY helpful. OK. What is a liner? What is a "dog leg"? -deb
The online oil and gas term glossary link that I attach will be useful to you and other readers of this post and site:
Gee Wiz , gonna guess all of the coal miners in that area are thrilled with that production !
The EPA has made Coal Fired Electric Generation way too expensive. The conversion to Nat Gas has already begun. The low price of Nat Gas is just speeding up the process.
Again, the gov't has "picked" a winner and a loser.
Nobody's a better venture capitalist than the US government.
Maybe, the coal industry needs to find an inexpensive process that can turn the coal into a liquid and/or gaseous type petroleum product?
What's happened to the coal industry is already happening to the oil/gas industry. Radical environmentalists, Obama, and the EPA have all but shut down the coal industry and caused what is left of it to increase coal costs due to all the petty regulations. They are already starting on the gas industry with the trumped up concerns over fracking, emissions from rigs and taxing everyone involved.
