WELLDIMS
-- Item 1: maximum number of wells in the model
-- - there are two wells in the problem; injector and producer
-- Item 2: maximum number of grid blocks connected to any one well
-- - must be one as the wells are located at specific grid blocks
-- Item 3: maximum number of groups in the model
-- - we are dealing with only one 'group'
-- Item 4: maximum number of wells in any one group
-- - there must be two wells in a group as there are two wells in total

GRID
-- The INIT keyword is used to request an .INIT file. The .INIT file
-- is written before the simulation actually starts, and contains grid
-- properties and saturation tables as inferred from the input
-- deck. There are no other keywords which can be used to configure
-- exactly what is written to the .INIT file.

PORO
-- Constant porosity of 0.3 throughout all 300 grid cells

-- The layers have perm. 500mD, 50mD and 200mD, respectively.

PERMY

PERMZ
-- Cannot find perm. in z-direction in Odeh's paper
-- For the time being, we will assume PERMZ equal to PERMX and PERMY:

-- Using values from Norne:
-- In METRIC units:
-- 859.5 1033.0 0.854 /
-- In FIELD units:

PVDG
-- Column 1: gas phase pressure (psia)
-- Column 2: gas formation volume factor (rb per Mscf)
-- - in Odeh's paper the units are said to be given in rb per bbl,
-- but this is assumed to be a mistake: FVF-values in Odeh's paper
-- are given in rb per scf, not rb per bbl. This will be in
-- agreement with conventions
-- Column 3: gas viscosity (cP)
-- Using values from lower right table in Odeh's table 2:
