I assume that is the blackbrush well northeast of cheneyville.  serial number 250723.

WJ Energy having some big problems here.

After tripping into hole with mud motor (directional equipment) on 2/20/18 to try to re-enter the original southern lateral (which I assume started at about 13,107'), they stick drill pipe (DP) on 2/25/18 after getting the bit to 18,123' (somewhere in the original lateral that they re-entered). They are stuck @ 14,228' - they appear to be trying to back off the fish (what is stuck in the hole) at 13,014' - meaning that they are looking to leave over 5000' of drill pipe and bottom hole assembly in the lateral.

Assuming that they can back off the fish, they have not trashed the southern lateral unless they can figure a way to unstick the fish and pull it out of the hole.

Odds on doing this are unlikely IMO. This could end up being a total failure

Hope things go better for Torrent as they have 3 wells permitted to Re-enter!!!  thanks for input RM

Who is WJ Energy ?  Ditto for Blackrush ?

Thanks!

Blackbrush (the well in question was drilled by them "x" years ago) is an established operator who has mostly done business in Texas over the years. Lot of horizontal and frac'ing experience - including the AC play in Karnes County.

WJ Energy (the company re-entering the old well) is a mystery for the most part - no website and I have never heard of them. Permit says that they are located on Audubon Street.

My bet is that they are a "front" operator for another company and not the primary group paying the bills and calling the shots here. Basically a contract operator.

And they have a train wreck on their hands based on the reports from December

BlackBrush extending the pad last few days, what is your opinion?

In reply to Doug Cox's comment about extending pad - which pad for what well location?

Rock man that would be serial number 250723. The one that is having the problem with the stuck drill pipe

OK, the W&J well. 

First question to people on the ground - is rig still on location here? Last report on SONRIS was Feb 25th. And if rig is there, can anyone comment on what is going on? e.g. appears to be drilling / rotating? Picking up casing? Pump trucks on locations? Anything?

Eyes on the ground is HUGE on this well right now (include pictures).

Assuming rig is still there and they are extending location, this may just be them making more room for equipment for drilling operation (things too tight right now). Or they may be making room for tanks / other completion equipment.

Bottom line - the reason for this could be tied to a lot of things / all dependent on what is happening as to the whole re-entry process

Doug Cox our excellent scout might can provide that info concerning whether or not the rig is still there and some pictures

Re: More Info on EOG well

Did some digging on the SONRIS site and found some tidbits of info that I am sure will be of interest to viewers on this site.

As you know, the report IP (flowing) for the Eagles Ranch well (as of 9/11/2017 report date) was 1120 BO, 1157 MCF & 2947 BW per day on a 64/64" choke with 1506# casing pressure (CP) - assume that this is flowing pressure up casing with no tubing in the hole.

This is from perforations between 16,275' and 20,550' MD.

SONRIS is showing two more tests in the "well tests" section down the page.

The DM-1R test (potential test) dated 9/22/2017 (and reported 11/1/2017) shows 2016 BO, 1837 MCF & 8373 BW per day with a flowing pressure of 3195# on a 46/64" choke.

A better test than the reported IP - looking like well cleaned up and improved a lot from that first test report. The total volume (almost 10,389 total bbsl of fluid ) is massive. But very high flowing pressure. This is 432 bbls fluid per hour.

This is also assuming that this is data for a 24 hour test - sometimes potential tests are reported for longer periods and you have to scale them down to per day rates.

All that being said, the more important test data is the next one - test on 10/29/20117 and reported on same day.

Assuming per day rates, test of 629 BO with 574 MCF and 1585 BW per day on an open (64/64) choke with only 288# flowing pressure.

This falls in line with the overall decrease in rate over time as this well flows back - in this case, a 69% oil volume decrease from 9/22 to 10/29. And a 90% decrease in pressure (from 46'64" choke to 1" choke). 

But totally logical and to be expected considering the well is flowing on its own. But the high water cuts are interesting (and a concern) / over 70% water cut 6-7 weeks after initial test reported.

Is there a chance that EOG frac'ed into water? Or that the AC has more bound water (that is now liberated) than expected? A percentage of this water is frac fluid for sure - but something to watch over time (if we are lucky to see more water test info).

SWD will be a big issue here (as in all frac plays of this type). 

Artificial lift is coming - probably either gas lift or ESP (electrical submersible pump).

Surprised no body noticed this on SONRIS before now.
