I think oil, whether spilled or whatever, has not been a favorite subject of SF writers. However, one of my all-time favorite books does revolve around the search for petroleum.
The original title, when it was first published in 1956, was THE DRAGON IN THE SEA, by Frank Herbert. It was re-issued in paperback in 1981 with the deceptive and deceiving title, UNDER PRESSURE. I think it may have been re-issued again more recently, with the original title.
It was THE DRAGON IN THE SEA that introduced me to Frank Herbert and led me to the original DUNE, which is a much longer and quite lyrical, but flawed novel, in my opinion. Unfortunately-- in my opinion, also, of course-- Herbert was never able to write anything to rival THE DRAGON IN THE SEA/UNDER PRESSURE.
It has been a while since I read it, but as I remember, at some future time, the US has completely depleted its petroleum reserves, and is now involved in a worldwide war. To make up for its lack of oil, the US sends out extremely powerful nuclear submarines that secretly drill into the offshore oil fields of its enemies. The stolen oil-- millions of barrels of it-- is held in enormous bags that are then towed home by the submarines.
The enemy, of course, does its best to interrupt this method of supplying petroleum, using sabotage at the subs' bases, and hunting through the ocean for subs that are stealing oil or that are towing it back to the US.
The book covers in remarkable and wonderful detail the perils encountered by the captain of one of the oil-subs beginning as the sub leaves its home base.
Although this book is not about an oil spill, it is certainly well worth reading.
