SOLUTION

-- no CO2 present in the reservoir initially
SWAT
	5*0.0
/

-- every block in the grid starts out water-filled
SOIL
	5*1.0
/

-- no pressure gradient in the reservoir

SCHEDULE

-- injector is at (1,1,1..1) and will be injecting CO2,
-- producer is at (5,1,1..1) initially giving water,
-- both wells is at 1000m depth and have a radius of 0.2m
