Mechanical Properties Card Syntax (EOR-BO)

Input Data Types

Character string (e.g., van Genuchten, porosity, m^3/s, Roe Superbee)

Integer (no alpha characters, special characters, or punctuation) (e.g., 1, 32, 195634)

Real (decimal points and exponential notation allowed) (e.g., 0, 0.0, 1.e-12, 1.E+3, 2.345)

Keyword (exact formatting required) (e.g., file, ~Solution Control Card, binary file)

Card Title

~Mechanical Properties Card,

Grain Density, Porosity, Compressibility and Tortuosity Factor

Repeat

Repeat for each rock/soil type

Info

IJK, JKI, or KIJ Indexing

Expand for Syntax

If Rock/Soil Name is IJK Indexing, JKI Indexing, or KIJ Indexing then a parameter value can replaced with an external file using the following formatting for ASCII files:

...,file:file name,...

or binary files:

...,binary file:

file name

,...

The external file will contain parameter values for every grid-cell ordered according to the indexing scheme (i.e., IJK, JKI, or KIJ). Units shown in the input line will be applied to all parameters in the external file.

Rock/Soil Name, Grain Density, Porosity

Rock/Soil Name,Grain or Particle Density,Units (kg/m^3),Total Porosity,Diffusive Porosity,...

Compressibility

Choose one compressibility option

Specific Storage

...Specific Storage,Units (1/m),...

Bulk Compressibility

...Bulk Compressibility,Bulk Compressibility,Units (1/Pa),Compressibility Reference Pressure,Units (Pa),...

...Compressibility,Bulk Compressibility,Units (1/Pa),Compressibility Reference Pressure,Units (Pa),...

Pore Compressibility

...Pore Compressibility,Pore Compressibility,Units (1/Pa),Compressibility Reference Pressure,Units (Pa),...

Info

If the Compressibility Reference Pressure is defaulted (i.e., null entry) then the initial grid-cell pressure will be used as the reference pressure. Reference pressures are recorded in the restart file.
