I don't think ERHE gets a share of the entire 65 percent and 60 percent respectively. I think ERHE gives up a piece of their sig bonus free portion (25 percent and 30 percent) for a carry to oil. The carrying company(PXD or NBL) gets a portion of ERHE's sig bonus free rights in return for carrying ERHE to oil AND the rest of the portion of the block that the consortium won. JMO. Regardless, the math does not work out as presented in the article.
