According to conjectures, the reservoir might have a potential deposit of one trillion cubic feet; however, PPL has not announced the actual size of the hydrocarbon potential. A PPL official said that the estimate of hydrocarbon reserve could not be guessed until the drilling reached the targeted depth and more tests were conducted.
