+;'''Barrel of Oil Equivalent (BOE)'''
+:The term allows for a single value to represent the sum of all the hydrocarbon products that are forecast as resources. Typically, condensate, oil, bitumen, and synthetic crude barrels are taken to be equal (1 bbl = 1 BOE). Gas and NGL quantities are converted to an oil equivalent based on a conversion factor that is recommended to be based on a nominal heating content or calorific value equivalent to a barrel of oil.  [http://info.specommunications.org/rs/833-LLT-087/images/PRMgmtSystem_V1.01%20Nov%2027.pdf?mkt_tok=eyJpIjoiTWpZNU1XWmtZMlZtWm1ReSIsInQiOiJ3WnJLWFF2RmNXamhJbGtLdXZRYlcwVTV1WmdSMFNnNUd3UzE2QUF0bUV0bGQrOFNJMHpIM1ppMHNJSFRZOStMU09DV1pBZ0N6Y2taanlQZU0zSkR1WEpaZjdsSGV2MG5iSGlCQmloSzNGbUpHbnhueTQ3bjFpWkJMcklDTGppSSJ9 Glossary of Petroleum Resources Management System - June 2018 (revised version)]

 :Behind-pipe reserves are expected to be recovered from zones in existing wells, which will require additional completion work or future recompletion prior to the start of production. In all cases, production can be initiated or restored with relatively low expenditure compared to the cost of drilling a new well [[#PRMS_2007|Appendix A: Glossary of Terms Used in Resources Evaluations - 2007 - 2.1.3.1]].

+:Reserves that are expected to be recovered from zones in existing wells, which will require additional completion work or future re-completion before the start of production. In all cases, production can be initiated or restored with relatively low expenditure compared to the cost of drilling and completing a new well including hook-up to allow production.  [http://info.specommunications.org/rs/833-LLT-087/images/PRMgmtSystem_V1.01%20Nov%2027.pdf?mkt_tok=eyJpIjoiTWpZNU1XWmtZMlZtWm1ReSIsInQiOiJ3WnJLWFF2RmNXamhJbGtLdXZRYlcwVTV1WmdSMFNnNUd3UzE2QUF0bUV0bGQrOFNJMHpIM1ppMHNJSFRZOStMU09DV1pBZ0N6Y2taanlQZU0zSkR1WEpaZjdsSGV2MG5iSGlCQmloSzNGbUpHbnhueTQ3bjFpWkJMcklDTGppSSJ9 Glossary of Petroleum Resources Management System - June 2018 (revised version)]
 ;'''Best estimate'''
 :With respect to resource categorization, this is considered to be the best estimate of the quantity that will actually be recovered from the accumulation by the project. It is the most realistic assessment of recoverable quantities if only a single result were reported. If probabilistic methods are used, there should be at least a 50% probability (P50) that the quantities actually recovered will equal or exceed the best estimate [[#PRMS_2007|Appendix A: Glossary of Terms Used in Resources Evaluations - 2007 - 2.2.2 & 2001- 2.5]].
