POSC Specifications: Epicentre Version 3.0 | Relational Implementation |
The ratio of effective permeability to absolute permeability for a fluid phase in a porous and permeable media in the presence of a second immiscible phase at a saturation condition. 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 medium is 100% saturated with the fluid phase. In practice, a third phase may be present but must at all times be immobile. In this case, the relative permeability values are always less than one. Relative permeabilities are expressed for the wetting and nonwetting phases as a function of wetting phase saturation.
- instance_s (PK, M: CHAR VARYING(19))
- Surrogate key of the table.
- instance_create_date (O: TIMESTAMP)
- e_and_p_data.instance_create_date
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.
- last_updated (O: TIMESTAMP)
- e_and_p_data.last_updated
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).
- r_rel_perm_orientation (FNK, M: CHAR VARYING(80))
- two_phase_rel_perm_point.ref_rel_perm_orientation
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.
Defines a foreign key to table r_rel_perm_orientation.
- r_two_phase_rel_perm (FNK, M: CHAR VARYING(80))
- two_phase_rel_perm_point.ref_two_phase_rel_perm
The kind of two phase relative permeability, such as nonwetting drainage or wetting imbibition.
Defines a foreign key to table r_two_phase_rel_perm.
- description (O: CHAR VARYING(2000))
- e_and_p_data.description
A remark or comment about the instance.
- instance_creator (O: CHAR VARYING(80))
- e_and_p_data.instance_creator
This is the person, company or application that created this instance. This identifies the party responsible for loading this instance.
- last_updated_by (O: CHAR VARYING(80))
- e_and_p_data.last_updated_by
This records the person or application making the update to this instance.
- source (O: CHAR VARYING(80))
- e_and_p_data.source
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".
- r_rel_perm_usage (FNK, O: CHAR VARYING(80))
- two_phase_rel_perm_point.ref_rel_perm_usage
The description of the intended meaning of the relative permeability value, usually based on the wetting phase saturation, such as residual, critical, connate, maximum or endpoint.
Defines a foreign key to table r_rel_perm_usage.
- two_phase_rel_perm_curve_s (FSK, O: CHAR VARYING(19))
- two_phase_rel_perm_point.two_phase_rel_perm_curve
This is the relative permeability curve that this point is defined as part of.
Defines a foreign key to table two_phase_rel_perm_curve.
- two_phase_rock_fl_interact_s (FSK, O: CHAR VARYING(19))
- two_phase_rel_perm_point.two_phase_rock_fl_interact
Specifies the system which has this relative permeability data.
Defines a foreign key to table two_phase_rock_fl_interact.
