POSC Specifications: Epicentre Version 3.0 | Logical Data Model |
The ratio of effective permeability to absolute permeability to a fluid phase in a porous and permeable media in the presence of two other immiscible phases at a condition of saturation. The relative permeability of a fluid phase is a number between zero and one (inclusive), and the relative permeability is one only when the porous media is 100% saturated with the fluid phase. Three phase relative permeabilities are expressed as a function of the wetting and nonwetting phase saturations.
- ref_rel_perm_orientation (M, K: ref_rel_perm_orientation(three_phase_rel_perm_point)) (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_point must have one ref_rel_perm_orientation.
- ref_rel_perm_usage (O, K: ref_rel_perm_usage(three_phase_rel_perm_point)) (C112, C138)
- The description of the intended meaning of the relative permeability value, such as residual, critical, connate, maximum or endpoint. Each three_phase_rel_perm_point may represent one ref_rel_perm_usage.
- ref_three_phase_rel_perm (M, K: ref_three_phase_rel_perm(three_phase_rel_perm_point)) (C138)
- The kind of three phase relative permeability, such as wetting drainage or intermediate imbibition. Each three_phase_rel_perm_point must be a kind of one ref_three_phase_rel_perm.
- three_phase_rock_fl_interact (O, K: three_phase_rock_fl_interact(three_phase_rel_perm_point)) (C112)
- Specifies the system which has this relative permeability data. Each three_phase_rel_perm_point may characterize one three_phase_rock_fl_interact.
- three_phase_rel_perm_curve (O, K: three_phase_rel_perm_curve(three_phase_rel_perm_point))
- This is the relative permeability curve that this point is defined as being a part of. Each three_phase_rel_perm_point may characterize one three_phase_rel_perm_curve.
- 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_point 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_point 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_point 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_point 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_point may have involvements with one or more object_activity_involvement. Inherited from object_of_interest.
- pty_three_phase_rel_perm_point (V: SET[0:?] pty_three_phase_rel_perm_point(three_phase_rel_perm_point))
- Each three_phase_rel_perm_point may have a property of one or more pty_three_phase_rel_perm_point.
- pty_two_phase_rel_perm_point (V: SET[0:?] pty_two_phase_rel_perm_point(three_phase_rel_perm_point))
- Each three_phase_rel_perm_point may have a property of one or more pty_two_phase_rel_perm_point.
