Python module for relative permeability/SCAL support in reservoir simulation

• http://equinor.github.io/pyscal

• API to create relative permeability curves through correlations or tables

• Similar for capillary pressure.

• Consistency checks for three-phase setups, makes your oil-water tables and gas-oil tables compatible

• Support for handling uncertainty, doing book-keeping for low, base and high cases, and the possiblity to interpolate between these cases using a number from -1 to +1.

There will eventually be some end-user scripts for this module

• create_relperm.py - will read configation from Excel worksheets with parameters, and produce Eclipse include files

• interpolate_relperm.py - reads low-base-high Eclipse include files, and interpolates between them

Illustrative example of how to produce a SWOF include file for Eclipse with a Corey relative permeability curve

from pyscal import WaterOil

wo = WaterOil(h=0.1, sorw=0.05, swl=0.1)
wo.add_corey_water(nw=2)
wo.add_corey_oil(now=3)
print(wo.SWOF())

which will produce the string

SWOF
--
-- Sw Krw Krow Pc
-- swirr=0 swl=0.1 swcr=0.1 sorw=0.05
-- Corey krw, nw=2, krwend=1, krwmax=1
-- Corey krow, now=3, kroend=1, kromax=1
-- krw = krow @ sw=0.46670
-- Zero capillary pressure
