POSC Specifications: Epicentre Version 3.0 | Relational Implementation |
A description of the behavior of relative permeabilities in a two 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. If a third phase is present in the fluid-rock system, it must be immobile. Relative permeabilities are defined for both the wetting and nonwetting fluid phases, and for both the drainage or imbibition processes.
- 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_curve.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_curve.ref_two_phase_rel_perm
The kind of two phase relative permeability curve, such as nonwetting drainage or wetting imbibition.
Defines a foreign key to table r_two_phase_rel_perm.
- two_phase_rock_fl_interact_s (FSK, M: CHAR VARYING(19))
- two_phase_rel_perm_curve.two_phase_rock_fl_interact
Specifies the system of the relative permeability data.
Defines a foreign key to table two_phase_rock_fl_interact.
- 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_model (FNK, O: CHAR VARYING(80))
- two_phase_rel_perm_curve.ref_rel_perm_model
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.
Defines a foreign key to table r_rel_perm_model.
