Undiscovered/untested basin – little or no exploratory drilling.
Undeveloped basin – oil has been found, but large areas remain unproduced.
Untapped resources – known to contain hydrocarbons, but not yet commercially exploited.
Among petroleum geologists, one of the strongest candidates for the world's largest largely unexplored oil province is the East Antarctic Sedimentary Basins. Geological studies suggest enormous sedimentary basins beneath Antarctica, but drilling for oil is prohibited under international treaties, so their hydrocarbon potential remains unknown rather than proven.
If you're asking about known oil-bearing basins with vast resources that remain only lightly drilled, common candidates include:
Orinoco Belt – the largest known accumulation of extra-heavy oil on Earth, with over a trillion barrels of oil in place, though much is difficult and expensive to produce.
Santos Basin – a giant offshore basin where major discoveries continue to be made and large areas remain underexplored.
Guyana–Suriname Basin – one of the most successful recent exploration frontiers, with large areas still undrilled.
Orange Basin – a major new frontier where several billion-barrel discoveries have been made in just the last few years.
If by "largest oil basin" you mean the largest petroleum basin overall, the West Siberian Basin is generally regarded as the world's largest hydrocarbon basin by area and resources, but it is certainly not undrilled—it has been extensively explored and developed.
Could you clarify whether you mean:
largest completely unexplored basin, or
largest known oil-bearing basin that is still largely undeveloped?
