POSC Specifications: Epicentre Version 3.0 | Logical Data Model |
The interfacial tension between two phases in a porous medium divided by the mean radius of curvature of the enclosing pore volume. This describes the pressure change at a immiscible fluid phase interface in a porous system at a single condition of saturation.
- ref_capillary_pressure (M, K: ref_capillary_pressure(capillary_pressure_point)) (C138)
- The kind of capillary pressure point, either drainage or imbibition. Each capillary_pressure_point must be a kind of one ref_capillary_pressure.
- ref_capillary_pressure_usage (O, K: ref_capillary_pressure_usage(capillary_pressure_point)) (C138)
- The description of the intended meaning of the capillary pressure value, such as threshold, irreducible, or critical. Each capillary_pressure_point may represent a meaning of one ref_capillary_pressure_usage.
- capillary_pressure_curve (O, K: capillary_pressure_curve(capillary_pressure_point))
- This is the capillary pressure curve that this point is defined as being part of. The rock fluid feature being characterized is described by the capillary pressure curve. Each capillary_pressure_point may characterize one capillary_pressure_curve.
- rock_fluid_interaction (O, K: rock_fluid_interaction(capillary_pressure_point))
- Specifies the rock and fluid combination for which this capillary pressure is descriptive. Each capillary_pressure_point may characterize one rock_fluid_interaction.
- nonwetting_phase (M, K: fluid_phase(nonwets_capillary_pres_point))
- The fluid phase that is designated as the nonwetting phase for the capillary pressure point. Each capillary_pressure_point must have as nonwetting one fluid_phase.
- wetting_phase (M, K: fluid_phase(wets_capillary_pressure_point))
- The fluid phase that is designated as the wetting phase for the capillary pressure point. Each capillary_pressure_point must have as wetting one fluid_phase.
- 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 capillary_pressure_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 capillary_pressure_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 capillary_pressure_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 capillary_pressure_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 capillary_pressure_point may have involvements with one or more object_activity_involvement. Inherited from object_of_interest.
- pty_capillary_pressure_point (V: SET[0:?] pty_capillary_pressure_point(capillary_pressure_point))
- Each capillary_pressure_point may have a property of one or more pty_capillary_pressure_point.
Local rules:
- Uniqueness Constraint
- ref_capillary_pressure, ref_capillary_pressure_usage, capillary_pressure_curve, rock_fluid_interaction, nonwetting_phase, wetting_phase
- Different Related Instance
-
Each CAPILLARY PRESSURE POINT must have as wetting a different instance of FLUID PHASE than the instance of FLUID PHASE that it has as nonwetting.
- Mandatory Relationship Set
-
Each capillary_pressure_point must either characterize a capillary_pressure_curv e or a rock_fluid_interaction.
