After a strong first half of the year, oil just posted its worst month since July 2015.
Despite fears that the commodity could retest the mid-$30 range, one closely-followed oil watcher is especially bullish on where energy is heading in the coming months and years—and investors should not get comfortable with currently low prices.
"It may get a little uglier with some European refinery shutdowns," admitted Tom Kloza recently on CNBC's "Futures Now" when discussing the potential for a near-term slowdown in the U.S. "But this is very seasonal."
The global head of energy analysis for the Oil Price Information Service (OPIS) explained that, while he expects to see a $39 handle for oil in the coming weeks, prices will see significant gains in the long-term.

"I'm pretty comfortable in predicting that crude oil prices will be much higher one year from now, two years from now, and three years from now with prices perhaps in the $50 to $75 range," Kloza told CNBC.
"But, like the New York Yankees, we may have to waddle through a long period of mediocrity and pain until things turn around," he added.
Crude oil hit a 2016 high of $51.67 on June 9, but has since fallen nearly to 20 percent.
