In this particular area there are surface indicators that show exactly where the shelf is and where the major regional faults are.
Are you familiar with the book - The Geology of Baton Rouge, I think that is the name of it? I looked for my copy a few months ago and cannot find it. It shows and discusses the basic geology of this area from South of BR to the Zachary area. If you follow the surface indicators that he walks the reader through in BR and along the BR fault and you then use those indicators to interpret the geology of the area North through Zachary. The surface indicators become very visible all the way to the shelf and beyond.
I think there is a lot of guessing being done about the possible phases of the EF or TMS. Until we get drilling data in this area none of these comments mean anything. All it does is cloud the issue and really works against the land/mineral owner. Why speculate? That's not where we need to be focusing. Again, why are you or anyone else bringing information from the EF in TX into this area? The EF and its phases has NOTHING to do with the "real" geology that we are looking at here. If you don't know or have the facts don't post it.
That being said, I do follow the leasing and lease prices in the EF. I think that there is enough similarity to warrant watching the leasing in that area and apply some of the tactics to this area.
Kirk's map is correct.
I don't know where these other maps are coming from other than a mapping service out of TX. This is not the first time I've seen this. They are simply not correct and I hate for anyone to be mislead by incorrect information. There is enough "bum steering" by the industry and landmen that we don't need anyone posting information that would put someone in a situation where they were taken advantage of because they got wrong info.
Again, as I posted earlier, there in no reason to post info that is pure speculation. That's what I'm seeing and it does no one any good. Until there is drilling data from THIS area; we have nothing but guessing. I don't see where that accomplishes anything. I'm here for knowledge and facts and I think a lot of other people are to.
