EnCana has reported several months of production from the first of their long lateral hz. wells in San Augustine County. I thought I'd share some comps. (with shorter laterals) so you can see the improvements... and judge for yourselves. Keep in mind that there have probably been other (than lateral length) changes such as # of perfs, # of stages, frac design (I started to say “recipe” but decided that would be really too “girl-ie”… ish) etc… .
ECA drilled their first well in the county back in 2010. It was the Black Stone Minerals A43 Unit #1H (405-30307) which came on @ a reported 32.000 MMcfd on a 28/64 choke with a 5659# flowing pressure (13 frac stages). By December it was producing an average of 2.131 MMcfd from a ~4400’ lateral. Here are the 2010 monthly numbers:
May – 397,411 mcf
Jun – 474,540 mcf
Jul – 293,300 mcf
Aug – 232,185 mcf
Sep – 168,306 mcf
Oct – 134,040 mcf
Nov – 103,238 mcf
Dec - 66,072 mcf Total (8 months) : 1,869,092 mcf
Cum. to date (51 months) 2,912,745 mcf
Black Stone A-398 Unit #1H (405-30335) was the next to come on, in August 2010, @ 23.424 MMcfd from a ~4,000’ lateral (18 frac stages) … a very strong well with a 9097# flowing pressure on a 27/64 choke. This has been a better producer than the first well which had a larger IP, a longer lateral and a steeper decline. Here are the numbers from 2010/2011:
Aug – 456,444 mcf
Sep – 463,548 mcf
Oct – 398,242 mcf
Nov – 350,209 mcf
Dec – 274,467 mcf
Jan - 215,532 mcf
Feb – 154,138 mcf
Mar – 136,338 mcf Total (8 months): 2,448,918 mcf
Cum. to date (48 months) 3,669,194 mcf
I am not going to include the A43 #2H (405-30369) because I think it was (most likely) a Bossier completion. I am also not going to use what I am calling the “Norwood, East” wells because I think (by my amateur analysis) they are finding different and/or thinner rock over there… so the well results are different. I will stick to just the “Norwood, West” wells for this exercise.
That brings us to the BSI Unit A47 wells. #1H (405-30414) and #2H (405-30445) both had a lateral length of ~7,500’ (both wells had 30 frac stages on completion reports). A47 #1H came on in Nov. 2011 (partial month).
Nov – 139,179 mcf
Dec – 415,211 mcf
Jan - 499,980 mcf
Feb – 452,522 mcf
Mar – 474,811 mcf
Apr - 238,836 mcf
May- 137,437 mcf
Jun- 169,052 mcf Total (8 months): 2,527,028 mcf
Cum. to date (33 months) 6,714,9896 mcf
A47 #2H came on in Dec. 2011 (partial month).
Dec – 428,947 mcf
Jan – 503,917 mcf
Feb – 481,450 mcf
Mar – 493,196 mcf
Apr - 235,660 mcf
May- 207,470 mcf
Jun- 163,640 mcf
July- 207,445 mcf Total (8 months): 2,721,725 mcf
Cum. to date (32 months) 6,925,986
This is not enough time to really compare these two new wells (to the others) but they are looking good, so far, and I will come back and add the production until we have eight months from all of the wells. The decline appears to be fairly flat (I’d do charts but I’m not an accomplished “chartist”… sorry) on both and they look set to eclipse (by far) the shorter wells at eight months in. This will give us something to while away our summer with… while we wait for the NG price to improve.
With over thirty months of production from the A47 wells it is now apparent that the longer laterals (~7500' vs.~4000') are far out-producing the shorter wells. What is not apparent are the differences in the later wells compared to earlier ones regarding number of stages, number of perforations per stage and frac design.
To give you another exemplar of a still later well in the area, to show that these are all evolving aspects of a horizontal well, the XTO - Banana Slugs DU #1H has an effective lateral length of 6,538' & was frac'd with 8,612,980# of sand. (Sorry, no data available on number of stages... but I will make a WAG that it is upwards of 28-30).
Banana Slugs DU #1H came on in May of 2013 (partial month) @ 15.332 MMcfd on a 17/64 choke with 8342# flowing pressure. It has exhibited gentle decline in fifteen (15) months of production and turned in 401,014 mcf in July, 2014:
May- 243,593 mcf
Jun- 463,670 mcf
Jul- 448,927 mcf
Aug- 461,712 mcf
Sep- 391,040 mcf
Oct- 431,454 mcf
Nov- 440,797 mcf
Dec- 472,418 mcf Total (8 months): 3,353,611 mcf
Cum. to date (15 months): 6,198,746 mcf
Banana Slugs DU #1H is on track to eclipse the A47 wells in just a few months as the A47 wells continue to decline.
T those permits in Z. Redmond Survey all expired but they have a nice big pad on the south side of 103 just west of the 147 intersection. Hopefully someone will drill when the gas price improves.
XTO filed a new permit in Z. Redmon: BSI Hawks DU #H 1 with 8799' lateral drilling north from the pad where the EnCana permits expired.
Updated 1-02-14 to add the cumulative production totals to all wells. It appears to me that the BSI A43 Unit wells were choked back after about four or five months but you can see that they have far and away beat the production from the earlier wells with much shorter laterals.
These two wells were the top producers in the East Texas "Shelby Extension" of the Haynesville Shale... until... EOG brought on the Sarge Unit #1H in north Angelina County (first production in March 2012 just a couple of miles due west of the A43 Unit) which has grossed 6,801,964,mcf in 21 months making the EOG-Sarge Unit #1H the top producing well in the East Texas Haynesville Shale... ever... and from a 5,100' lateral. The Sarge is also the deepest Haynesville horizontal completed in Texas to date with a TVD of 15,828'. On the IP test it flowed 16.190 MMcfd, had a 9,915# flowing pressure on a 19/64 choke and a 12,015# shut in pressure, which makes it the highest pressure recorded to date, and a bottom hole temp. of 416 deg. F (yes, another record).
jffree1 , it appears to me that the EOG Sarge #1H is as much as 20 miles or more west of the EnCana A-43 Unit, which would place it more than a "couple miles" due west of the A 43 Unit. Am I missing something?
You are closer to correct than I am. Google Earth puts it at 18.3 miles as the crow flies (and I should have looked). I was thinking "just across the river" which it is... but I was thinking of the wrong river (Attoyac instead of Anglina). Sorry about that. Post in haste, repent at leisure, etc...
I would just add that all of that territory in between is probably good rock, don't you think? And probably getting a bit better as you go west. The unknown now is how far south and west, I think. Time will tell.
With the exception of a couple Goodrich wells, which I think may have had some mechanical issues, and several Exco wells in the J. Walker, A-57 survey,there is a lot of undeveloped acreage between the EnCana A-43 and the EOG Sarge 1H Unit. I cant think of any reason why the acreage wouldn't be developed by someone eventually. As you say, it should be good rock. I'd love to have an interest in a few wells like the Sarge 1H.
As you may remember, we are less than 2 miles due west of A-43. I actually had an Independent Landman email me late December wanting to shop our land around if we weren't leased. I updated our non-leased status & told them to get to work.
Look for activity by XTO. They permitted the BSI/USFS Unit F6 #1H in late January. It is a location on which EnCana allowed their permits to expire.
Speaking of XTO... Banana Slugs DU #1H, Lease ID #269459, has produced 3,353,611 mcf in 8 months from a ~6900' lateral. That unit is just north of you.
Thanks for the info! I haven't checked GHS in a while. We're still leasing dormant but time is our friend. NG in the $4.80 range & holding. The huge Freeport LNG export facility has been permitted & construction will start next year! Another Freeport plant going in to convert dry gas to exportable LNG slated to start soon. Life is GOOD....
I recently leased a small amount of minerals in the Morgan Berry, A-59, just east of A. Spear, A-43 to XTO. Their intention is to drill a well in the not too distant future. Jffree1 mentioned the Banana Slugs #1H well, in which I also have a small interest. Thru 11 months the Banana Slugs has now produced 4,471,327 mcf, which may very well be the 2nd best Haynesville well in the play including the Louisiana Haynesville, I acknowlege that it does have a 6,900' lateral, which is longer that virtually all the Louisiana wells. In March, 2014, after 11 months, it was still producing 12 million cu ft a day. It is a big well and is second only to the Sarge 1 H .
I scaled the distance on GIS Map Viewer from bottom of Banana Slugs #1H lateral to our northern most boundary. (1-3/4 miles)
Walkers in Nac Co to the west (2-3 miles), BS-A43 /F16's to the east (1-3/4 miles), & now Banana Slugs just north. Surely we'll see some action as NG demand increases.
The anticipation is starting to build again. Thanks for the info...
XTO is operator now on the EnCana wells in San Augustine. Just an FYI.
