Spearfish Formation: Sweet or Sour

I posted this earlier today -- in fact, it was my first post of the day, but it may have been overlooked: there seems to be confusion over whether Spearfish oil is light oil or sour oil. Link here. Or maybe I'm misreading / confusing something.

Update: see comments below.

This is very basic stuff but I simply missed it. Sweet/sour has to do with sulfur content. Heavy/light has to do with viscosity.

  1. No confusion. Spearfish crude is both light (specific gravity) and sour (sulpher content)
