SIOR has already secured 8230 acres of leases inn the play & have options on 15,000 additional acres at a set price (though it is rumored that they have already exercised these options)...
The crude production in this play is such that Sandridge & Chesapeake claim that it is the most economically sound play in North America... though to answer your question, I think that these wells produce both light sweet crude & light sour crude at about a 50/50 ratio... These two grades of crude are not soluble in one another - one looks like cooking oil, the other looks like black cooking oil on floats on top of the sweet crude... very easy to separate... The sour crude must be trucked off location to sell, whereas the light sweet crude can be put into the pipelines...
