According to CoinMeta, ExxonMobil ( XOM ) stated on Monday that it has signed a memorandum of understanding with Venezuela's state-owned oil company PDVSA with the aim of exploring potential upstream business opportunities in Venezuela. ExxonMobil did not disclose the specific projects or oil fields it is evaluating. If this American oil giant ultimately proceeds with the development projects, it would mark ExxonMobil's return to the country nearly twenty years after its withdrawal.
