This Subtopic addresses supplemental disclosure requirements for oil and gas operations. Required disclosures include: 1. a [Proved oil and gas reserve](https://asc.understandingaccounting.org/glossary/p/#proved-oil-and-gas-reserves "Proved oil and gas reserves are those quantities of oil and gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulation before the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether the estimate is a deterministic estimate or probabilistic estimate. The project to extract the hydrocarbons must have commenced, or the operator must be reasonably certain that it will commence the project, within a reasonable time.The area of the reservoir considered as proved includes all of the following: The area identified by drilling and limited by fluid contacts, if any Adjacent undrilled portions of the reservoir that can, with reasonable certainty, be judged to be continuous with it and to contain economically producible oil or gas on the basis of available geoscience and engineering data. In the absence of data on fluid contacts, proved quantities in a reservoir are limited by the lowest known hydrocarbons as seen in a well penetration unless geoscience, engineering, or performance data and reliable technology establish a lower contact with reasonable certainty.Where direct observation from well penetrations has defined a highest known oil elevation and the potential exists for an associated gas cap, proved oil reserves may be assigned in the structurally higher portions of the reservoir only if geoscience, engineering, or performance data and reliable technology establish the higher contact with reasonable certainty.Reserves that can be produced economically through application of improved recovery techniques (including, but not limited to, fluid injection) are included in the proved classification when both of the following occur: Successful testing by a pilot project in an area of the reservoir with properties no more favorable than in the reservoir as a whole, the operation of an installed program in the reservoir or an analogous reservoir, or other evidence using reliable technology establishes the reasonable certainty of the engineering analysis on which the project or program was based. The project has been approved for development by all necessary parties and entities, including governmental entities. Existing economic conditions include prices and costs at which economic producibility from a reservoir is to be determined. The price shall be the average price during the 12-month period before the ending date of the period covered by the report, determined as an unweighted arithmetic average of the first-day-of-the-month price for each month within such period, unless prices are defined by contractual arrangements, excluding escalations based upon future conditions.") quantities (see paragraphs [932-235-50-3 through 50-11B](https://asc.understandingaccounting.org/asc/235/932/#235-932-50-3) ) 2. b Capitalized costs relating to oil- and gas-producing activities (see paragraphs [932-235-50-12 through 50-15](https://asc.understandingaccounting.org/asc/235/932/#235-932-50-12) ) 3. c Continued capitalization of [exploratory well](https://asc.understandingaccounting.org/glossary/e/#exploratory-well "An exploratory well is a well drilled to find a new field or to find a new reservoir in a field previously found to be productive of oil or gas in another reservoir. Generally, an exploratory well is any well that is not a development well, a service well , or a stratigraphic test well.") costs (see paragraphs [932-235-50-1A through 50-1B](https://asc.understandingaccounting.org/asc/235/932/#235-932-50-1A) ) 4. d Costs incurred for property acquisition, [exploration](https://asc.understandingaccounting.org/glossary/e/#exploration "Exploration involves both of the following: Identifying areas that may warrant examination Examining specific areas that are considered to have prospects of containing oil and gas reserves, including drilling exploratory wells and exploratory-type stratigraphic test wells."), and development (see paragraphs [932-235-50-17 through 50-20](https://asc.understandingaccounting.org/asc/235/932/#235-932-50-17) ) 5. e Results of operations of oil- and gas-producing activities (see paragraphs [932-235-50-21 through 50-28](https://asc.understandingaccounting.org/asc/235/932/#235-932-50-21) ) 6. f A standardized measure of discounted future net cash flows related to proved oil and gas reserve quantities (see paragraphs [932-235-50-29 through 50-33](https://asc.understandingaccounting.org/asc/235/932/#235-932-50-29) )
