POSC Specifications: Epicentre Version 3.0 | Logical Data Model |
Changes in the net quantities of proved reserves. These changes describe the re-classification of proved reserves from one category to another, possibly due to a change in the recovery process being utilized.
- original_reserves (O, K: reserves(amendment))
- The proved reserves which were the original description of reserves. The reserve change describes information about this original proved reserve being changed to a new category. Each reserves_category_change may be based upon one reserves.
- result_reserves (M, K: reserves(derived_from))
- The proved reserves that are the result of the reserve change. Each reserves_category_change must support an estimate of one reserves.
- ref_reserves_change_reason (M: ref_reserves_change_reason(reserves_category_change)) (C138)
- The reason that a reserves change was made. Each reserves_category_change must made for one ref_reserves_change_reason.
- delta_gas (O: ndt_std_volume_gas)
- The change in standard volume of gas.
- delta_liquid (O: ndt_std_volume_liquid)
- The change in standard volume liquid.
- description (O, I: ndt_comment) (C117)
- A remark or comment about the instance. Inherited from e_and_p_data.
- instance_create_date (O, I: ndt_date_tod) (C126)
- This is the date that this instance was created. This date is defined by the source if imported, or is the date the instance is created if a new instance. Inherited from e_and_p_data.
- instance_creator (O, I: ndt_identifier) (C126)
- This is the person, company or application that created this instance. This identifies the party responsible for loading this instance. Inherited from e_and_p_data.
- last_updated (O, I: ndt_date_tod) (C126)
- This is the date that this instance was last updated. This value should be updated when any part of this instance is altered (except for inverse relationships). Inherited from e_and_p_data.
- last_updated_by (O, I: ndt_identifier) (C126)
- This records the person or application making the update to this instance. Inherited from e_and_p_data.
- source (O, I: ndt_identifier) (C126)
- The provider of this instance, which is usually a data provider for imported/purchased data. If this instance is provided by POSC, then this attribute must be "POSC". Inherited from e_and_p_data.
- data_collection (I, V: SET[0:?] data_collection_content(collection_part)) (C020)
- Indicates the data collections that include this instance of E and P data. Each reserves_category_change may be a member of one or more data_collection_content. Inherited from e_and_p_data.
- 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. Each reserves_category_change may be included in one or more document_information_content. Inherited from e_and_p_data.
- graphical_element (I, V: SET[0:?] graphical_element(depicted_object))
- Specifies one or more graphical elements which are depicting this data item. Each reserves_category_change may be depicted by one or more graphical_element. Inherited from e_and_p_data.
Local rules:
- Uniqueness Constraint (C056)
- original_reserves, result_reserves
- Different Related Instance
-
Each instance of RESERVES CHANGE cannot create a revised estimate of the same instance of PROVED RESERVES that the RESERVES CHANGE instance is based upon.
- Same Related Instance
-
The fluid component for the original reserves must be the same as the fluid component of the resulting reserves.
