Energy stocks ran up sharply following word of OPEC production cuts, but Jim Cramer says investors should wait for a pullback to buy. Cramer says he's top three energy stocks to buy on a dip are: Schlumberger (SLB) - Get Report , Apache (APA) - Get Report and EOG (EOG) - Get Report . Cramer says he can't recommend buying a stock on the day prices are surging. OPEC agreed to its first production cut since 2008 on Wednesday, sending oil prices up as much as 8% at midday. OPEC will reduce production by about 4.5 percent, or 32.5 million barrels a day.
