I dont know the exact way to interpret this well's actual days of production but it appears that this vertical well drilled in union Parish in 2009 obviously produced 4300 bbls of oil sometime during Aug.10-20th 2009, an impressive amount of oil from an open hole completion in the LSBD. Took about 30 drilling days to TD.
Another thread mentioned this as THE WELL that kicked off this play.
Well, here is the Sonris report:

please add in any further infrences that can be made from the information therein

Yes, in the completion report they called it condensate. The gravity was reported as 50, as compared with the 59 gravity reported for the BML well. I'm not sure where the gravity demarcation between oil and condensate is.

I just noticed at SONRIS Lite that a DT-1 test of the WB Exxon Mobil well on 3/30/2013 (reported 5/1/2013) shows that the WB produced 324 BCPD and 449 MCFD on what appears to be an open choke (64/64). Could this be correct? If so, this would represent a large opening up of the choke from the SDM2G test of 1/2/2013 when the well produced 504 BCPD and 1019 MCFD on 10/64 choke, and would imply that the decline rate is greater than it appears.

What we really need to see is the flowing tubing pressure. As mentioned above, the choke can be opened to maintain the rate until the choke is all the way open, then the true decline rate can be determined.
Interestingly, SONRIS Lite reports a flowing pressure of 3500 for both the 3/30/2013 and 1/2/2013 tests, so something doesn't add up. Also, the reported production for the full month of April averaged 312 BCPD, down only slightly from the test of 3/30/2013. If this April production was at 64/64 choke setting, it seems the decline during the month would have been greater.
I, along with others, have speculated that WB ran into a fracture system that is feeding their well. Just like in the Austin Chalk, if natural fractures do exist, you can get some monster wells if you hit the fractures just right. If this is true, the trick is going to be determining the fracture prone areas and drilling there.
With the possible exception of the Dean vertical test, it does not look like SWN has had the luck(?) that WB had in terms of hitting fractures. They just seem to be drilling in areas where their casing is falling apart.
This well has grossed ~$5mm in six months so far...as a vertical. It is likely a 400k+ bbl EUR?
If they drill an horizontal well on this unit, it'll be huge.
If SWN or any other operator considered a horizontal here a slam dunk, I think W-B would have found them by now. Of course W-B could be asking more than a larger operator is willing to pay at this point in time. Regardless, why would any operator want to drill horizontal wells at $10-$12M per each if they thought they could get similar long term production from vertical wells at $1 - $1.5M?
Something else is at play with this W-B well proximity. If there were no barriers, the pipepline would have been in place in 2010 and there'd be dozens of verticals(despite horizontals bringing higher recoveries) all around this well.
This well is outperforming Eagleford verticals by 4X. Even the Dean 31 horizontal is performing in line with Eagleford verticals. A horizontal here by the W-B well could turn some heads, it appears, as this well had no fracks. What would a 5400' wellbore with 20 stages do in this well's rock?

AboutAs exciting as this is, we know that we have a responsibility to do this thing correctly. After all, we want the farm to remain a place where the family can gather for another 80 years and beyond. This site was born out of these desires. Before we started this site, googling "shale' brought up little information. Certainly nothing that was useful as we negotiated a lease. Read More |
