While it would bring development to Guyana, the presence/location of oil is not a new initiative.
There have been other searched with similar indications when issues were not as good between the US_of_A and Venezuela.
Situation now is the same as before, hence the major push for oil search and production in Guyana.
As soon as conditions normalize between US_of_A and Venezuela, efforts for the search of oil in Guyana, unfortunately, will gradually cease.
