Exxon Mobil has struck an initial agreement aimed at returning to Venezuela, paving the way for the company to potentially resume oil production in the nation.

The tentative deal brings the largest oil company in the United States a step closer to pumping crude in Venezuela once again. Exxon Mobil originally ceased its operations and left the country nearly two decades ago.

If finalized, the arrangement would mark a significant return to Venezuelan production for the American energy giant following almost twenty years away.
