Currectly handling GOC below and WOC above the reservoir The phase pressure of water and gas is set to inf when WOC and GOC is above and below the reservoir. This make sure the minimum saturation values are picked for these cases.
Fix sign error in the specified oil pressures at at WOC and GOC
The oil pressure at the contact for the special cases:

contact	location	po(contact)
GOC 	above 	-inf
GOC 	below 	+inf
WOC 	above 	-inf
WOC 	below 	+inf
