RE: QEC gas in Lowlands!So I guess that despite the reality of sedimentationa prerequisite for oil (such sediments can continue for great depths and strangeley enough can in certain instances be overlain with basaltic rock...) with further consideration for the assumption that most oil deposits uncovered are from the Jurassic to the Silurian (with an absence of deposits from teh cambrien to precambrien-when life started..(uh !)- it is certainly wiser to gain in depth knowledge of the age of the rocks being investigated ! Mind you that despite having a casula interest in the matter, I'm far from being knowledgeable enough to give more concrete descriptions once dealing with geology. Although I'm aware (like most other people) that sedimentation of organic material is a prerequisite to creat an oil field ! As for michigan, despite teh complete faulting indicating techtonic activity accountable for it , it is apparent that despite the potential seepage resulting from such faulting , if there is proof of sedimentation, the possibility of a compatible environment for oil deposits makes the area worthy of consideration. Mind you that by what I heard , there has been drilling undertaken in most compatible areas of the continental US including places like Alabama and Tenessee (in relative proximity to the Misssissipi an example being the properties owned by Montello resources https://www.montello.com/s/Home.asp ) without forgetting places in the north west like wyoming such as with Derek oil https://www.derekoilandgas.com/s/Home.asp .
Thus the understanding is that it is apparent that despite the obvious with regards to land based deposits, there is still some renewed exploration even if the continental shelves themselves most probably represent the best bet to uncover major oil deposits in North America...
