Should You Invest In Sandridge And Other Mississippian Lime Players?
So, is the Mississippian the “New Bakken?” Perhaps not, but it does seem to be a very profitable for companies such as SandRidge which were in early. Some Seeking Alpha authors have written about a massive price decline in oil. Others are bullish and see an imminent rise in oil’s price. If you are persuaded by the bulls, now may be a good time to invest. If you like the bears argument, wait until oil declines and then maybe consider investing in these companies.
In any case, with large international oil companies such as Repsol (REPYY.PK) initiating joint shale/carbonate ventures, the migration to horizontal fracking seems well entrenched going forward.
