Are there any Horizontal wells drilled in the Hosston (aka in East Texas--Travis Peak)

formations-- if Not Why?

adubu, that's above my pay grade.  In general, horizontal drilling is utilized in "tight" formations where insufficient permeability exists for hydrocarbons to flow to a well bore.
OK-- Some one may jump in with the answer-- Les B--you have thoughts about Austin Chalk?

Adubu, I do not have information concerning the formation parameters in the older, oil producing region of the Giddings Field so not familiar with the type of wells and completion designs utilized.  I would assume most would have been vertical unfrac'ed completions.  Of course they may have utilized acid jobs to improve productivity. 

 

In some cases horizontal wells have been used in reasonably productive oil plays just to enhance the economics over vertical wells.

Les B-- my understanding from years ago was told the Vertical drilled well in the Chalk had to hit one of the natural frac that ran vertical themself  to make a well worth anything therefore they drilled horizontal to hit as many of the frac as possible to flow into well bore.  The Austin chalk H wells came on line with high IP but then got long in the tooth very rapid like in  few months in most wells and did not payout very well.
aduba,  you are right about this. The laterals are drilled perpindicalar to the strike of the joints (fractures) in the chalk. This can very greatly increas production rates.

Adubu,

 

There's one horizontal Austin Chalk well about 10 miles NW of our place here in Washington County which must have hit the motherload of all natural fracs.

 

The Neumann Unit #1 was originally drilled by Union Pacific Resources in July of '96.

 

Dry Gas only, but an IP of just under 80 mmcfd.    To date, the well has sent a staggering 32.335 Billion CF of NG to sales.   

 

Peak month was in Oct '96 with just under 1.8 BCF produced in that month alone.  

 

Chesapeake also had another monster AC well in the county in '99,  with their Tiemann 1H.

 

That one has also produced 32.329 BCF to date and is set to surpass the Neumann well as the county's top producer once the production numbers for April/May 2011 get updated.

 

We should all be so lucky to see a monster like one of these come in.

DJG-- WOW that up there with some of the "Pinnacle Wells" Love to have minerals in that unit.
Also..Horizontal wells in what has been coined as "resource plays" which are large deposits  of oil/gas with large areal extent

Skip, back in the late 40's or early 50's, I was working as a "roughneck" for my Dad , we were drilling in the Waskom area, in the 3000 to 3500 feet range, Fredrickburg I think. As I remember, Halliburton set up and fracked there wells with oil and sand, taking a long time for the process, the exhaust on the engines would turn red from heat. I am 76 years old and could be wrong in my memory. Does anyone know or remember this? These wells would come in making 40/50 barells a day and would end up in the 10/12 per day. I studed Geology but ended up in sales.

Thanks for all your in info, still love everything about the oil patch. Leased to Chesapeake, small lot in 15 17 15 .

Gale, I have reviewed wells that were completed in the early-1960's that were fraced in the Caddo Pine Island field.  I suspect that early types of fracture stimulation were commonly employed in that decade, if not earlier.  I have not run across any information on the pressure pumping equipment utilized in those early fracs.  I also find the history and the evolution of drilling technology of great interest.
PJ, fracture stimulation of deeper horizons (ie Haynesville Shale) would have no direct impact on shallower oil fields in the area.  Initially the new Haynesville Shale production may have caused capacity issues with the existing gas gathering systems but eventually new gathering networks were installed specifically for the Haynesville Shale production.
Don't want to want to beat a dead horse here, but...today  in far west-- Ft. Worth a university lab will start tests on water wells in areas where fract'n is going on with Chesapeake. By now in the oil [bidness W. texas for business] it seems incredible that if there exists a connection, it has not been noted. If there is not a connection, why wouldn't we have scientific data or a report from whatever they call the ongoing geologist reports in a drill process?
