Return to status quo.
Oil reserves were nationalized decades before Chavéz so they're not getting privatized.
America remained the main buyer of oil even under Chavéz, and this only changed very recently with some sanctions. Oil exports would once again flow to America, with China, Turkey and other markets getting less.
PDVSA was staffed with cronies whose mismanagement drove production to the ground. A change in power may bring in a normal leadership which will slowly repair the damage.
Because Venezuela is nearly a Somalia-level failed state, mining of gold and other minerals has grown to resemble the Congo. Paramilitaries and criminal gangs now share control of this sector of the economy (see https://www.caracaschronicles.com/2019/04/21/inside-ciudad-guayanas-illegal-gold-retail/). If the power vacuum is filled and normal governance returns, those mafias will act more discreetly and at least superficially mining will once again be a normal and legal activity.
