Found in the Midland Basin of the Permian, the Spraberry trend was discovered back in 1948.

While the rest of the top Permian fields continue their long-term decline, output in the Spraberry increased 200% within just four years!

And this story gets even better...

Directly beneath the Spraberry lie even more pay zones that companies will soon exploit, one of which is the Wolfcamp Shale. Keep this name tucked away somewhere safe, because it's going to shape future headlines in the oil industry...

Unlike the Spraberry Formation, which has been drilled for more than 70 years, the Wolfcamp was only recently opened up after drillers combined horizontal drilling techniques with hydraulic fracturing.

It's actually one of the few places left in the U.S. that's more active than the Eagle Ford Shale.>>>>
