Actually the wiki leans to yes. Presuming the wiki information is correct, then they have found oil/gas off shore. If I recall the definition of a continent is much more than just the physical land above water. It extends well into the oceans as well. Hence off-shore is very likely still on-continent.
Oh, I forgot to add the disclosure to my prior response: "I am not a geologist, nor do I play one on tv or broadway".
