NUMBER
Eff_Length_Thickness_Ratio double No_Unit

The height and kh terms should either both be net or both be gross. (POSC Epicentre Version 3.0) No

For linear aquifers, this parameter is defined as: (Linear_Penetration)/ (0.001127 (height) (width)).

Fluid_Diffusivity double Area_Per_Time

The characteristic of a rock-fluid system that describes the relationship of pressure change in time to pressure gradient. Also called hydraulic diffusivity, this term is mathematically defined as permeability divided by the product of porosity, fluid viscosity and fluid compressibility. (POSC Epicentre Version 3.0) No
NUMBER
GOC double Depth
m
The depth of the bounding surface in a reservoir above which predominantly gas occurs and below which predominantly oil occurs.Gas Oil Contact (GOC). No
NUMBER
GUID STRING128 NA
Globally Unique IDentifier for an instance of a class. USAGE NOTES: There are two cases: 1) GUID is not populated or used; and 2) it is populated with a value that is globally unique. If the GUID is populated there are two means of doing so for a given project: 2a) Seabed automatically generates and populates the GUID when an instance is created (valid only on Oracle based systems); and 2b) the GUID is generated and populated by an application (other than Seabed) on instance creation. Whether Seabed automatically generates GUIDs for a project is determined by the Auto_GUID flag in SDS_Account. Note that techniques 2a and 2b can coexist in the same project. When GUIDs are automatically generated an application can override the automatically generated GUID with its own GUID by simply supplying the GUID value. Applications that generate their own GUIDs and populate the GUID column will function correctly on projects which have automatic GUID generation turned on. No
