Hi Bubba, Thanks for the conversation and status trust. I’ll send info - but it was found via google most likely, and it’s stored on my laptop which I don’t have with me today. At any rate, my main source of my understanding of the Smithwick formation is the University of Texas, Bureau of Economic Geology (BEG) website. Their list of publications and maps and other references are the best, and I bet you’re already dialed in there. Their digital map of oil plays for Texas (Dutton, et al.) is great - it’s been awhile, but I believe the Fort Worth Basin and Smithwick Formation and Bend Formation is very informative - much if it historical - hope this is helpful!
Kind Regards, Ralpr
