So what you're saying is that Delta T, or change in time, which has always meant more porosity the higher the value isn't neccessarily the case these days? Isn't that basically the measure of resistivity?
Or are you saying basically they won't really know what's up until they complete some test wells?
Also, as to my original question... It seems odd that this activity in Vernon Parish is centered around an old play (Austin Chalk). Is this just the start of speculators trying to get some cheap leases in hopes that the TMS or Eagle Ford is present and viable?

By delta T I assume you are talking about a sonic log or equivalent measure of porosity? That has no bearing on resistivity. Porosity is the foremost key to any productive formation, and always will be. If there isn't adequate storage space in the rock then commercial quantities of oil and or gas won't exist. Permeability can be induced through fracturing but porosity cannot be induced. Resistivity measures resistance and is used to determine if a formation is hydrocarbon bearing or water bearing, among other things. The issue currently which the Indigo wells will give some indication of is what causes the lower resistivity values in their area. It is currently unknown as to whether the older logs in their area had resistivity readings influenced by carbonate, clays, etc. in the actual rock. As to the Austin Chalk, that play looks like a money maker if oil stays above $100 a barrel in select places. Anadarko is probably the foremost player through their acquisition of Union Pacific Resources Corp. They have all the data from the failed play in the 1990's which resulted in only a few select areas with commercial wells. Chesapeake was the only survivor from a host of others playing the 1990's chalk who either went broke or got bought out. I doubt lease values will be very high for either play because they are going to be so economically challenging at this stage. No one has ever to my knowledge completed a commercial TMS well. If this changes then certainly values could rise. Good chalk wells exhibit steep decline rates and will need a good oil price in the early life of the well to justify drilling.
The geologist with the Tuscaloosa blog does a good job of explaining a lot of the current challenges and activity in his write ups.

Yeah.

Ok, I got ya. I'm interchanging log types that aren't the same.

I'm wondering what the economic pros and cons the TMS will have on the region? If the Florida Parishes have the road infrastructure, hotels, or pipelines to handle this sort of play. Where are all of these workers going to sleep? St Francisville has one hotel and a handful of bed and breakfasts. Also, in my experience, the Feliciana's are somewhat clannish and although the economic benefits are obvious, I am wondering how the citizens of these sleepy towns will tolerate the traffic and noise.
I'm trying to compile a report comparing other shale plays to the Tuscaloosa as far the positive and negative. Let me know if you have any feedback

Tuscaloosa Marine Shale
In recent quarters, a handful of independent exploration and production (E&P) outfits have touted their acreage in the Tuscaloosa Marine Shale (TMS), a formation that stretches from Texas to Louisiana and Mississippi. The field is far from a new discovery; famed Mississippi wildcatter Alfred Moore spearheaded drilling in the TMS in the 1960s.
The play’s proximity to the Haynesville Shale should make it easier for producers to redirect drilling rigs from the out-of-favor dry-gas play and limits bottlenecks associated with a lack of midstream infrastructure. Despite boasting similar geologic characteristics to the Eagle Ford, the TMS is far from a slam dunk, which explains the low prices that early movers have paid to build an acreage position.

interception, which area of evangeline parish?

Encore's last well came on at 300+ BOPD from only 3 frac stages, but declined rapidly due to what many speculated was the quick closing of the fractures.

I'm sure that's part of the potential Devon and Encana see here. They will surely experiment with different types of fracs and different proppants. What works in one play doesn't necessarily work the same in others. The key is going to be mineralogy here, as most people don't realize that the Eagleford is more of a carbonate and the Bakken is more of a dolomite. Most of the rest of the "shale" plays are more dry gas plays and it's easier to move gas molecules through these rocks than oil molecules. Encore also had a ton of drilling problems with the formation. Devon and Encana are both top notch north american shale drillers so if the play can be made into a success they are probably some of the best candidates to do so. It will be interesting to see the decline rates on the first few new wells.

This was a second hand info out of Mamou. I believe VP is going to fall into the Shale considering it's northern proximity to Mamou.

me? muscle? i have no idea who that is.

If the mineralogy of this play is a big question mark, where arent more conventional and rotary cores being obtained?
