The behavior of capillary pressures between two fluid phases in a porous and permeable media as a function of wetting phase saturation.

ref_capillary_pressure (M, K: ref_capillary_pressure)

The kind of capillary pressure curve, either drainage or imbibition.


rock_fluid_interaction (M, K: rock_fluid_interaction(capillary_pressure_curve))

Specifies the combination of rock and fluid for which this capillary pressure data is descriptive over a range of saturations. Each capillary_pressure_curve must characterize one rock_fluid_interaction.


nonwetting_phase (M, K: fluid_phase(nonwets_capillary_pressure_curve)) (1169)

The fluid phase that is designated as the nonwetting phase for the capillary pressure curve. Each capillary_pressure_curve must have as nonwetting one fluid_phase.


wetting_phase (M, K: fluid_phase(wets_capillary_pressure_curve)) (1169)

The fluid phase that is designated as the wetting phase for the capillary pressure curve. Each capillary_pressure_curve must have as wetting one fluid_phase.


description (O: ndt_comment)

A remark about the capillary pressure curve.


capillary_pressure_point (V: SET[0:?] capillary_pressure_point(capillary_pressure_curve))

These points are defined as being on the capillary pressure curve, but may or may not be part of the geometry of the curve defined by pty capillary pressure curve. Each capillary_pressure_curve may be characterized by one or more capillary_pressure_point.


data_collection (I, V: SET[0:?] data_collection(collection_content))

Indicates the data collections that include this instance of E and P data. Each capillary_pressure_curve may be a member of one or more data_collection. Inherited from e_and_p_data.


datum_for_ranking (I, V: SET[0:?] object_ranking(base_object))

Indicates that an object is being used as a basis for comparison with another object. Each capillary_pressure_curve may datum for ranking one or more object_ranking. Inherited from object_of_interest.


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_curve may be depicted by one or more graphical_element. Inherited from e_and_p_data.


object_of_ranking (I, V: SET[0:?] object_ranking(ranked_object))

Indicates that an object is being classified in a rank order based on its characteristics. Each capillary_pressure_curve may object of ranking one or more object_ranking. Inherited from object_of_interest.


pty_capillary_pressure_curve (V: SET[0:?] pty_capillary_pressure_curve(capillary_pressure_curve))

Each capillary_pressure_curve may have a property of one or more pty_capillary_pressure_curve.

Local rules:

Uniqueness Constraint
ref_capillary_pressure, rock_fluid_interaction, nonwetting_phase, wetting_phase
Different Related Instance
Each CAPILLARY PRESSURE CURVE must have as wetting a different instance of FLUID PHASE than the instance of FLUID PHASE it has as nonwetting.
