Trump announced a deal for 65 billion barrels of Venezuelan oil. How much of that is actually investable?

Trump said Friday the US has majority control of more than 65 billion barrels of Venezuela’s proven reserves through a partnership with private business. He says it more than doubles US reserves and "will cut gas prices" and Rubio put private investment around $100 billion. For me the biggest question is, how many years of capex and field work would it take before this shows up in production, crude prices, or stocks? The size of the headline is not the same as the size of the trade cos as much as Venezuela sits on the world’s largest proven reserves, it only produces about 1.25 million barrels a day. The contract, the fields, and the operators still have not been published and i saw some reports describe a joint venture and long-term offtake... not a simple purchase. Chevron (CVX) is the US major already operating there and was reported to be in talks to add fields. Halliburton (HAL) has been mentioned on the services side. Exxon (XOM) and Conoco (COP) are the other names people will watch if this turns into real workovers and new wells. Reserves on a slide are not barrels at the pump.
