I am of the opinion that there were contradictions as to how wealthy Blake was. In the first episode, Krystal's friend quotes Blake's wealth as being equal to $200 million dollars. We also learned that Blake owned 70% of Denver-Carrington. Even if Blake's entire net worth was tied up in the company and he had no debts, that placed the value of the company at $285 million or $200 million divided by .70.
However, we know that Blake owned the house, his football team, and other holdings. So, let's say that he had 70% of his assets tied up in Denver-Carrington. That would reduce the value of the company to $200MM with Blake owning 70%, or $140MM in company stock and having $60M in net worth else where, assuming that he was debt free. Even in 1980, though, $200MM would have been small potatoes for a major oil company.
However, I think it's safe to assume that Blake had a lot of debts. It seemed like his company ran on a high level of debt because his Middle East losses almost crippled him financially. His debt service on these lost holdings left him scrambling. For example, maybe Denver Carrington was a billion dollar company with Blake owning 70%, or $700MM, but having $500MM in debts. That would explain his net worth of $200M, but also explain why the Middle East crisis left Blake in such a bind.
However, consider this too: With Blake on the verge of going bankrupt, a $9MM loan from Cecil kept him from losing everything. Blake also told Steven that he wanted a job on a rig, that he had 22 of them. 22 oil rigs is not that much for a multinational oil empire. Also, he must have been leveraged to the hilt if he was worth $200MM but a $9MM loan saved him from the poorhouse. It seems like Blake could have raised $9MM pretty easily if he needed too unless every dollar was already spoken for.
