My advice to you is that if you are taking Accutane, stop it right now. If you are considering taking Accutane, dont do it. It is simply too dangerous.

Here is a partial list of the side effects: dry skin, dandruff, headaches, hair loss, liver damage, bleeding from the nose, decreased night vision, birth defects and even arthritis or complete loss of vision, The list goes on.

Now i dont know why your skin got oily... but Accutane is poison, you should stop taking it.
