POSC Specifications: Epicentre Version 3.0 | Logical Data Model |
A description of the behavior of relative permeabilities in a two phase fluid rock system. Relative permeability is the ratio of effective permeability for a fluid phase to the absolute permeability of the fluid body containing it. If a third phase is present in the fluid-rock system, it must be immobile. Relative permeabilities are defined for both the wetting and nonwetting fluid phases, and for both the drainage or imbibition processes.
- ref_rel_perm_orientation (M, K: ref_rel_perm_orientation(two_phase_rel_perm_curve)) (C112, C138)
- The orientation of the relative permeability curve within the porous medium. Examples are isotropic, vertical, horizontal, along bedding plane, normal to bedding plane, x direction, y direction, z direction, etc. Each two_phase_rel_perm_curve must have one ref_rel_perm_orientation.
- ref_two_phase_rel_perm (M, K: ref_two_phase_rel_perm(two_phase_rel_perm_curve)) (C138)
- The kind of two phase relative permeability curve, such as nonwetting drainage or wetting imbibition. Each two_phase_rel_perm_curve must be a kind of one ref_two_phase_rel_perm.
- two_phase_rock_fl_interact (M, K: two_phase_rock_fl_interact(two_phase_rel_perm_curve)) (C112)
- Specifies the system of the relative permeability data. Each two_phase_rel_perm_curve must characterize one two_phase_rock_fl_interact.
- 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 two_phase_rel_perm_curve may be a member of one or more data_collection_content. Inherited from e_and_p_data.
- 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 two_phase_rel_perm_curve 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. Each two_phase_rel_perm_curve 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 two_phase_rel_perm_curve may be depicted by one or more graphical_element. Inherited from e_and_p_data.
- involving_activity (I, V: SET[0:?] object_activity_involvement(involved_object)) (C056)
- This are the activity involvements which affect the object. Each two_phase_rel_perm_curve may have involvements with one or more object_activity_involvement. Inherited from object_of_interest.
- pty_two_phase_rel_perm_curve (V: SET[0:?] pty_two_phase_rel_perm_curve(two_phase_rel_perm_curve))
- Each two_phase_rel_perm_curve may have a property of one or more pty_two_phase_rel_perm_curve.
- ref_rel_perm_model (O: ref_rel_perm_model(two_phase_rel_perm_curve)) (C112, C138)
- The model used to define this relative permeability curve. This concerns information about the construction of the curves and methods of interpretation, including hysteresis behavior. Each two_phase_rel_perm_curve may represent one ref_rel_perm_model.
- two_phase_rel_perm_point (V: SET[0:?] two_phase_rel_perm_point(two_phase_rel_perm_curve))
- These are the points that are defined to be part of this relative permeability curve. Each two_phase_rel_perm_curve may be characterized by one or more two_phase_rel_perm_point.
