The scale that is used for gravity indexing is showing approx. a $30 price per barrel decline for March as compared to February yet the oil prices per barrel have been higher. Has anyone been to the ConocoPhilips site to check this out? Our minerals are in Fallon County which is bordering ND and we are under the central montana index gravity rating of "g". I have contacted Conoco and have gotten no reply. Also, does anyone know if we can take a loss on our income because of the adjustment for transporting?
