I apologise for not reading the wiki link sooner.
1. The link talks about an exploratory platform. _Presumably_ this would involve lower volumes of material, and at lower pressure.
2. Even if the leaks were identical, it would be possible for the required assets to be differently dispersed. They might also be differently organised. By which I mean differently owned, but also differently regulated under law, requiring (probably) more detailed negotiation of use wrt indemnity.
