How can you compare CVN to SSN? Its like comparing Durian to Toffee Apples!
Different country, differnet geology, differnet drilling techniques, differnet stage of exploration & production (not getting into that one!!), completely different overheads re managment, drill contractoes, ownershio vs lease of rigs, frac crews etc etc
Only common link is they are both listed on ASX.
All IMO
Maddoc
