In the WSJ article entitled "Crazy Bets on $200 oil...", the article notes the large amount of open option contracts with exercise price of $100/bl. of oil. If oil prices continue to surge and go above $100/bl. then for the participants in this particular market:

Only call option buyers will see higher profits

Both call buyers and sellers will benefit and have higher profits

Only call option writers (e.g. sellers) will see increased profits

Neither buyers or sellers will benefit because option contracts are a zero sum game
