What's this article actually about - the journal or the subject?

edit

The title and sole reference of this article suggest that it is about the academic journal Petroleum Geoscience - also implied by the categories and wikiprojects. However, the introductory paragraph, and most of the rest of the article excluding the final three sentences, seem to be about petroleum geoscience as a subject (seemingly because of copied content from the Petroleum geology article?). What is the intended topic of this article? I'm happy to be involved in editing but would like advice on the direction to head. Pierre Tack (talk) 15:14, 30 May 2017 (UTC)Reply
