$GLND Here are the biggest oil discoveries of all time by oil and gas companies.
GLND could top them all off as I have provided evidence that we could have over 86+ billion barrels of oil.
If we just go by the 13 billion estimates, that would still be the biggest oil discovery in the past 60+ years.
(Note, Prudhoe Bay Alaska's discovery was around 6 billion, but later produced over 13 billion barrels of oil to date)
