if each of the 7 zones fail commercial flow, then each one will be tested,
then you will get exactly that happening

you cannot easily produce from a well with many varied pressure zones, you produce one at a time unless engineering allows otherwise..

but lets assume this lowest one flows commercially, then that section will be put on production, none of the others will be tested or produced until many years from now in this particular well

there is some data from the wirelines, so you could assume (in the case of just this zone being produced) that the wirelines will give indications of the other sandstones being equally potentially as good if not better.. so more wells will be drilled, to test those regions, and there are many options available to the jvp in terms of how to complete this well still..

early days.. and imho the last announcement is very positive. if porosity and permeability factors are good then we may just see our first commercial zone
