littleasy,

It looks to me like this is either a test of the well or a well in production with gas being flared. The column to the left in the first photo is a heater/treater. It separates Oil and water. The 6 tanks are probably 500 barrel tanks which would allow 3000 bbls per day production. The portable tanks are probably for salt water storage from production. I don't think this is a frack job. The chalk is fractured and to my knowledge no one to date is doing any fracking or gravel/sand packing and you would not have a flare burning during a frack or a gravel/sand pack. Also, they don't appear to have any pumpers on site. You would need them for a gravel/sand pack. Wish the photos were better but it was a good try.

Looks like every frack job that I have ever seen going on.

Thanks Joe

I went to the sight because I was hearing rumors of a collapsed hole. I did not know what I was looking for but this did look like a well going into production because of the tanks. I did not see any pumpers. The only thing that I did notice that looked different to me was a large number of green pick up trucks. I did not see a company name but my guess ia Anadarko since their sign was green. I hung around the area for a while looking for tankers moving oil but did not see any. If you open the jpgs that I posted earlier you can zoom in closer. Thanks again.

Injection maybe Joe? Craig's rumor of a collapsed hole is close to what I have been hearing although not that drastic. They may be trying to open it back up like Deshotel and Dominique. Both injection jobs on those were successful. I was thinking frack too at first glance but Lacour43 is an AC well and I don't see any pumpers either sp it wouldn't make sense.

If this ain't a frack then they must be expecting a lot of water?

Two Dogs, 43 was already producing 600 bowd and, correct me if I'm wrong, when they hit it with nitrogen injection it cleans out the hole really, really well. Wouldn't that require the tanks?

Watt, you got me, I was just looking at pictures that looked like a frack job to me in the first posts. I haven't kept up with what is going on down in that neck of the woods. They could be shooting anything down hole and I wouldn't know about it cause I am snowed under buying leases in different parts of the play for the the past 2 months.

Joe and other members,

I have heard locally that they may inject gas into the well.  There is also talk of a pumper unit.  Take a look at Kirk Barrell's two most recent posts on his Tusc Trend blog (Austin Chalk - Yield; Production Decline Rates).  The AC-West and AC-East as defined by yield (bbl/mmcf) may be instructive as to the performance of LaCour 43.   "Recent discoveries in both regions have yields that align with the ranges.  One might not necessarily be better than the other.  These complex, fractured, carbonate reservoirs might respond better to more or less gas.  Time will tell." - Kirk Barrell

Well said littleasy. Even if you get the big hit on an AC well it will fall drastically for the first eight to ten months before the decline slows. Then it'll hold for a number of years. Historically they've gone back in at year two and injected it, opened it back up and got another serious eight months. Decline rates are really severe in the AC. I've yet to see one hold the gaudy numbers they get when they originally hit but for some reason the O&G companies aren't able to capture that first lick yet. Just about all of those old 90s wells are still producing, albeit only 500-700 bopm.

I still think its a well in test or production. If you have followed some of my posts in the past one of the things that has and will plague the AC is formation collapse. One way that a mentor of mine and I discussed years ago was the need to do a gravel/sand pack in the Austin Chalk. Its a process where sand/gravel are pumped into the formation to hold it open but not to the point of fracking it. This should be considered especially in high production wells where the formation is very naturally fractured and prone to collapse. As far as the injection of nitrogen in the Deshotels is concerned it appears they are using it to break up mud that was pumped into the formation while drilling. If that works then great. One thing I don't understand is why they shut the Deshotels well in after the injection and are considering putting a pumping unit in the well. With the pressures quoted in the IP that would be another mistake.

Joe,

If there is collapse after the IP data was reported, would that not explain the need for some form of remediation?

How was Belco so successful in the AC back in the 90s Joe? Turner 22-1 was a short dual much like what Atinum has been doing. I don't remember them packing any of those wells though.
