I've been working in the drilling industry, from the 'crown to the ground', for 40 years. A hole without issues is very rare. Considering that horizontal, and fracs are just out of their infancy, issues can be expected. These first wells are really a learning experience, and things will improve with every well drilled. If the engineers and geologists didn't think it wouldn't, the oil companies would have cut out before now. It's all about economics. Just because the third grade is hard, doesn't mean you can skip it, and go to the fourth. Good times are ahead. I tend to look at the glass half full, and it's worked for me for over 60 years.

yes, good times ARE ahead.  My questions revolve around just how good and how far ahead.

My wife keeps telling me to be patient, I want to tell her something else altogether, but she owns the lease, so I'll keep my mouth shut!

Good post Mr. Henson and thank you for it.

An old oil man assured me when I was young that there are almost always problems drilling an oil well and getting it on production; and that the worst one was that it is a dry hole.

There aren't going to be any of those in the Tuscaloosa---at least not in the way that awful word  "dry" is customarily used in the business.

I'm waiting for the first dual completion frac job. I think there will be such an animal, and don't think it will be too far in the distant future.

dual completion frac job

What is that?

I believe it is called a zipper frac and was tried in the Ash Wells.

There have been three "dual" zipper fracks, all by EnCana.

The Weyerhaeuser 60H 1 and 2 in St. Helena Parish...screwed up by trying 750,000#s of proppant per stage.

The Ash 1 and 2 in Amite County.  One well here was screwed up when drilling out the plugs...the other wasn't very good because of either 1 million #s per stage or 750,000 #'s per stage.

The final "dual" were the Anderson 17-2 and 17-3 wells, which were completed mostly using the believed to be best known way to drill and complete...with a few exceptions. 

These wells were drilled in the same direction side-by-side, while the Weyerhaeuser and Ash were drilled north and south of each other.

The 17-2 is an okay well, but was a bit short...about 5000'.  I think it was drilled under the "Rubble" Zone. 

The Anderson 17-3 has been a disappointment.  It was a 7000'+ lateral, but isn't doing as well as the 17-2.  Neither well seem to be as good as the Crosby or even the previous two Anderson wells.

The IP rates were lower than expected on 17-2 and 17-3 but there is still an outside chance, since the decline rates have leveled off on both wells at a decent rate (in the high 200-300 boepd range),that they could rival the 17-1 and 18-1 in ultimate recovery if they stay at these levels for a long time - this is a possibility with the new pumps. My theory is that they may have opened the chokes too rapidly on these wells and silted up some of the fractures, in addition to the laterals being shorter - just a WAG.

The good news is that almost all of the problems have been mechanical and not formation related - especially since Goodrich found they could stay above the rubble zone and still produce sufficient quantities of oil. When everything goes smoothly on the drilling and completion end, the oil cometh forth consistently. The Huff well delays are supposedly minor equipment issues. An experienced driller is running that rig but he may be babysitting an inexperienced crew and a rig on its last leg in a drilling environment that requires everything/everyone to be hitting on all cylinders all the time. I believe they have the TMS largely figured out now and will make it work.

Not to change the subject but, has a figure been projected on bbl. @ acre production, production curve, and finally, gravity of the crude in Wilkinson/Amite wells drilled so far by both Goodrich, and Encana? I hope I've asked my question correctly.

 Gravities are in the 40s. Estimated Ultimate Recoveries range from 400k barrels to above 800k barrels(Crosby) depending on the well. Barrels per acre, I am not sure how that would be calculated or if it is calculated that way? The Goodrich web site has presentations that may answer some of your questions such as cumulative production curve by well. Here is an example:    http://www.goodrichpetroleum.com/presentations/MgmtCurrent.pdf
