There's no readily available information confirming that any university in Cyprus offers a specific undergraduate or postgraduate degree program explicitly titled "Petroleum Geosciences." Cyprus's economy and geography aren't heavily focused on petroleum exploration and production. While universities in Cyprus may offer related courses in geology, geophysics, or environmental science that touch upon petroleum-related topics, a dedicated petroleum geosciences program is unlikely.
To be certain, you would need to check the course catalogs of individual universities in Cyprus.
