POSC Specifications: Epicentre Version 3.0 | Logical Data Model |
A description of the behavior of relative permeabilities in a three 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. Relative permeabilities are defined for wetting, intermediate wetting, and nonwetting phases, and for both the drainage and imbibition processes.
- ref_rel_perm_orientation (M, K: ref_rel_perm_orientation(three_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 three_phase_rel_perm_curve must have one ref_rel_perm_orientation.
- ref_three_phase_rel_perm (M, K: ref_three_phase_rel_perm(three_phase_rel_perm_curve)) (C138)
- The kind of three phase relative permeability behavior, such as intermediate drainage or imbibition. Each three_phase_rel_perm_curve must be a kind of one ref_three_phase_rel_perm.
- three_phase_rock_fl_interact (M, K: three_phase_rock_fl_interact(three_phase_rel_perm_curve)) (C112)
- Specifies the system which has this relative permeability data. Each three_phase_rel_perm_curve must characterize one three_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 three_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 three_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 three_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 three_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 three_phase_rel_perm_curve may have involvements with one or more object_activity_involvement. Inherited from object_of_interest.
- pty_three_phase_rel_perm_curve (V: SET[0:?] pty_three_phase_rel_perm_curve(three_phase_rel_perm_curve))
- Each three_phase_rel_perm_curve may have a property of one or more pty_three_phase_rel_perm_curve.
- pty_two_phase_rel_perm_curve (V: SET[0:?] pty_two_phase_rel_perm_curve(three_phase_rel_perm_curve))
- Each three_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(three_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 three_phase_rel_perm_curve may have one ref_rel_perm_model.
- three_phase_rel_perm_point (V: SET[0:?] three_phase_rel_perm_point(three_phase_rel_perm_curve))
- These are the points that are defined as part of this relative permeability curve. Each three_phase_rel_perm_curve may be characterized by one or more three_phase_rel_perm_point.
