with russian contractors backing Maduro for safety, and heavy Chinese and Russian  loans, I think Maduro and Petro is not yet gone, my only concern is that in the location of the supposed Oil plant, there is nothing more than hungry/angry people and no oils plants yet  supposed to back Petro token.

Also venezuelan oil is heavy oil mean specific technics are require to make gazoline, and those rafineries  are in united states, also the oil venezuela production fall from 3 millions barrells to 1.4- 0.7 million, as venezuela exchange trade balance is 90% dependant on oil sells, the situation is not going to change without external help.

Finaly even if the oil is there, It will require years to build oil facilities, and who's gonna supply materials ? who's money ?
