The Mississippian Carbonate Play is much bigger than you imagined. I would like to expand the formation to include Pre-Cambrian formations further north in the United States. This blog will consist almost entirely of figures and diagrams and one hyperlink to a interesting USGS article. If I used words, there would not be enough space, plus the diagrams and figures and the referenced article convey the information better than I ever could by written words in this given format.
The Mid-continent rift system is correlated with the carbonate shelf, and the other geologic formations in this system of interest are much older because they are Precambrian in age. The point is that the same general trend extends Northerly for many miles for both the Mississippian Carbonate Play and the Precambrian formations referenced in the USGS paper at the bottom of this blog via hyperlink. Yes, Precambrian formations can produce fossil fuels! The best examples are in Mongolia and Russia - where the Precambrian oil and gas formations and speculation have been in the news.
i'm trying to learn something about this, but not sure exactly what yet. I guess it's the meaning/usage of the word 'carbonate'. -- I'm monitoring pretty closely 2 counties in N.N/E Oklahoma, Pawnee and Noble, which are just N/W of the orange colored area labeled 'Fatetteville and Caney Fms' in illustration 2. Those two counties aren't colored. There's quite a bit of drilling activity in Noble now, has been some in Pawnee and will be more again soon, all in the Mississippian depths. Is that NOT Mississippian carbonate?
Hi Larry,
Thanks for the question. Carbonate is the technical term for limestone essentially. The other main type of carbonate/limestone is dolomite - this is limestone with a large ratio of magnesium in it. So, if that is play they are aiming for then it should be what you ate hoping for. I know the term “Chat” is used a lot in describing the drilling targets, but “Chat” is a way of describing or including Chert (also known as Flint, like used on old guns or in arrowheads) - and from what I have read companies are generally trying to get away from calling it Chat - the limestone (or Carbonate like I’ve been saying). Hope this helps!
Though I am able to destinguish the location on the county chart where exactly Logan County OK is located, I still find it general disturbing that nearly all of these charts leave non-petroleum educated people pretty much in the dark. I like to skip around this site, seeing what is going on, what might come to be, and especially how people in general are reacting to it all. I am very dissappointed that we are on the outskirts of what is probably the biggest oil boom in the history of our nation, but people are so downbeat about it all. There is a serious lack of enthusiasm, there is no motovation, everybody is saying "not in my back yard..." and "It ain't gonna happen because it never has been done..." stuff like that. I own a measly 1.6548333 acres on a gross of 160. and I am still tremendously excited about our nations coming wealth. Hip hip Hoorah!!! for the Oil magnates and executives. Let's get it on and have the fun doing it for all of our great and wonderful nation.
Hi Mr. Von Wilson,
It appears there are many in Logan County, OK that can steer you in the directions you want to go! Thanks for your comments. The more specific maps for play are proprietary mostly. But these plays are so vast that one can know a lot.
