STONE1EX

Recognised by the OPM Flow parserPROPS

This keyword defines the exponent used in Stone’s250 Stone, H. L. “Probability Model for Estimating Three-Phase Relative Permeability,” paper SPE 2116, Journal of Canadian Petroleum Technology (1973) 22, No. 2, 214-218. first three phase oil relative permeability model as modified by Aziz and Settari251 Aziz, K. and Settari, A. Petroleum Reservoir Simulation, London, UK, Applied Science Publishers (1979), page 398.. The STONE1EX keyword should only be used in three phase runs containing the oil, gas and water phases and when the STONE1 keyword in the PROPS section has been used to activate Stone’s first three phase oil relative permeability model.

Notes:

The keyword is followed by NTSFUN records as declared on the TABDIMS keyword in the RUNSPEC section.

Each record must contain only one value and is terminated by a “/”

There is no “/” terminator for the keyword.

If the STONE, STONE1 and STONE2 keywords are not present in the input deck then the default three phase oil relative permeability model is employed.
