  1. For all geographic areas other than North America, includes stratigraphic wells that have been plugged and abandoned, and excludes exploration wells that are currently suspended and awaiting completion or abandonment.
  2. A productive oil or gas well is an exploratory, development or extension well that is not a dry well.
  3. A dry well (hole) is an exploratory, development or extension well found to be incapable of producing either oil or gas in sufficient quantities to justify completion as an oil or gas well. The term ‘‘completion’’ refers to the installation of permanent equipment for the production of oil and gas, or, in the case of a dry hole, to reporting of abandonment to the appropriate agency or authority.
  4. North Africa includes Algeria and Tunisia.
