Wonder if the oil company execs, boards and shareholders are convinced by the sudden change in rhetoric. I am certainly not. The Chavistas quite literally ran Venezuela’s oil production and infrastructure into the ground before, and Rystadt Energy has calculated that it will take 10-15 years and tens of billions of USD in renewed investments to just get back to 1990-2000s level of production numbers, aka 3 million bpd. That might be an overtly negative assesment but the point still stands. Chavistas have expropriated US companies (Exxon and Conico still have tabs standing out), mismanaged and undermaintained the oil sector and infrastructure and staffed the PVSDA with regime loyalists instead of experts whilst inviting foreign state owned companies before, they are in no shape or form reliable or suitable partners.
There is more though, oil sector prefers working in a environment of political stability and quiet and deregulated business climate. Like Guyana next door, won't be surprised if the US oil sector just goes for Guyana whilst paying lip service to Trump and the Venezuelan Project whilst quietly sidestepping it. Venezuela is not like Guyana and won't be like Guyana. Instead the removal of Maduro, continued naval embargo and emerging factionalism within Chavismo signal the beginning of a new era of political unrest.
