Experts deliver another round of Eagle Ford bullishness {South Texas oil/gas}

The Eagle Ford produced 30.5 million barrels of oil in 2011, up from 4.4 million barrels in 2010, Texas Railroad Commission figures show. Natural gas production rose to 243 billion cubic feet in 2011, compared with 108 billion cubic feet in 2010.

.......truly stunning! Is there any way to guess what kind of time frame a play like this will keep producing in a meaningful way?

The nation faces a glut of natural gas...Natural gas is a victim of its own success

Strategic Forecasting, doesn’t expect the price of natural gas to exceed $6 per million British thermal units over the next decade...the U.S. is headed toward an energy renaissance.

There you go. We have NG, we have NG pipelines, we have CNG vehicles and conversion kits.

Now all we need are lots and lots of CNG filling stations.

Japan’s Kyodo news agency reported that the U.S. will ask other countries to release spare oil reserves when the Group of Eight meets this Friday.***********

This jackleg in the WH doesn’t give a crap about energy security. Crude is down to about $93 and he wants international reserves released just to help his floundering campaign.

I hope the other countries tell him to go pi** up a rope.

I think it is too early to give reasonable numbers of duration projections.

They are still finding new areas the formation reaches with economically recoverable reserves.

Tight formations like the Bakken and Eagle Ford do drop off quickly for production rates per well. But the number of wells being drilled continues to grow offsetting the per well decline.

This is good news but don't worry, the WH will find a way to screw it up.
Taxes, regulations, environment, some underground protected sand worm, give the rights and control to China, Brazil or UN...
No way are they going to stand by idly and let the US of A benefit from it.

One of the problems facing Eagle Ford development right now is market. Since the nation is awash in natural gas, and storage is full, there is no demand for all the Eagle Ford gas. Even the liquids-rich portion of the Eagle Ford produces less than 100 BO/mmcfg, and you can’t produce the oil without producing the gas. No one wants to flare the gas, the formation is too tite to re-inject, so you must find a market for gas to sell oil.

This is a really good reason to push the LNG export projects. Once a stable/better market for gas is established, it becomes more feasible to drill wells at a faster rate.

Even the liquids-rich portion of the Eagle Ford produces less than 100 BO/mmcfg.

Where did you get that number, it cannot be correct.

In 2011, the entire Eagle Ford formation produced 243 billion cubic feet of gas and 30,453,253 barrels of oil.

So the entire field, dry gas to liquid rich, averages 125 barrels of oil for each million cubic feet.

Also note the natural gas liquid production is about 84 barrels NGL per mmscf on top of the oil.

My reading shows that the EF is going to last quite long. Indications, early, show that the wells if choked back initially, will drop only 50% in the first five years then slowly decrease over the next 20 years.

Is there even a 5 year old well in the Eagle Ford?

[Sea Parrot]

LNG exports will take care of the excess, If the Obamanites refuse to allow LNG port facilities to be built for LNG ships, I am sure Mexico will be glad to let them be built there

Thanks for that link.

In that blog post:

See graph below which is based on data from old wells. (Note that no information was provided as to where these vertical Eagle Ford shale wells were located and what completion methods were used.)

If those “old” wells are from before 2008, they are not from the Eagle Ford.

Eagle Ford was first drilled by Petrohawk (now owned by BPH Billiton) in 2008.

Sorry, I meant to include this in the previous post.

In that same blog post:

One Eagle Ford shale decline rate chart can be found here: Eagle Ford Well Decline Curve It shows EOG Resources wells (mostly in the oil window) peaking at around 350 BOE/D, and flattening out pretty fast after eight months to less than 100 BOE/D.

This is a rather quick drop down in rate, less than a 1/3 after less than 1 year.

Thank you for providing better figures on the GOR’s. The problem of gas market remains. But twice the liquids production makes a big difference.

[thackney]

Yes, but South Texas has a decent existing infrastructure for Natural Gas pipelines already.

This map should be clearer to read.
