WWR increases counterparty risk, which is why I have marked oil refinery..My answer chosen was OTM with oil producer. The reasoning is such OTM put, means that we are betting on oil price go down, but our counterparty's financial and credit position is directly related to the growth of oil prices. So in case of huge price drop, we would be elegible to earn huge profits, but our counterparty might be bunkrupt by that time. Oil refinery as pointed above, benefits from price drop, so no WRR here.
