(a)
Includes
the number of wells completed during the applicable year regardless of the year in which drilling was initiated. Excludes any wells where drilling operations
were continuing or were temporarily suspended as of the end of the applicable year. A dry well is a well found to be incapable of producing hydrocarbons in sufficient quantities to justify completion.
A productive well is an exploratory or development well that is not a dry well.
(b)
Indicates
wells drilled in the proved area of an oil or natural gas reservoir.
