POSC Specifications: Epicentre Version 3.0 | Logical Data Model |
Estimated volumes of crude oil, condensate, natural gas, natural gas liquids, and associated substances anticipated to be commercially recoverable from known accumulations from a given date forward, under existing economic conditions, by established operating practices, and under current government regulations. Reserves estimates are based on interpretations of geologic and/or engineering data available at the time of the estimate. Reserves do not include volumes of crude oil, condensate, natural gas, or natural gas liquids being held in inventory. If required for financial reporting or other special purposes, reserves may be reduced for on-site usage and/or processing losses.
- pfnu (M, K: pfnu(reserves)) (C112)
- Indicates the facility for which reserves are estimated. Each reserves must be attributed to one pfnu.

- reserves_category (M, K: reserves_class(reserves)) (C108)
- This is the definitive classification of reserves that defines its fundamental meaning. This always points to a reserves_class defined within a formal hierarchy, usually be a governmental agency or standards organization. Additional reserves_classifications are intended to provide additional characterizations without changing this fundamental meaning. Each reserves must be defined by one reserves_class.

- amendment (V: SET[0:?] reserves_category_change(original_reserves))

For example, this may be the contract designations that define the specific interest ownership fractions of the business object as it is bought and sold. Each reserves may be subject to one or more contract_object_designation. Inherited from business_object.
- data_collection (I, V: SET[0:?] data_collection_content(collection_part)) (C020)

- derived_from (V: SET[0:1] reserves_category_change(result_reserves)) (C151)
- This designates the reserve change that created this instance of reserves. For example, the producing proved reserves of the ABBEY field were derived from the behind pipe proved reserves. Each reserves may be derived from one reserves_category_change.
- derived_interest (I, V: SET[0:?] derived_interest_makeup(interest_for)) (C071, C122)
- These are the ownership fractions for business associates of this object. Each reserves may be referenced by one or more derived_interest_makeup. Inherited from object_of_interest.
- document_information_content (I, V: SET[0:?] document_information_content(e_and_p_data)) (C136)
- These are the document specification parts that include this data value and define its meaning within a document specification. Each use may define a different meaning, and many uses are allowed.
