Will the horizontal Spraberry rival the Wolfcamp?

Report summary

The Permian-aged Spraberry is one the of earliest targeted formations in West Texas but more than seven decades of vertical drilling and EOR activity have only yielded modest production growth. Now, a select set of operators, who are able to identify and target favourable geologic zones, are revisiting the complex formation with horizontal wells and modern fracturing techniques to generate production growth that rivals their Wolfcamp positions. Permian pure players are not the only companies promoting the potential of the Spraberry. ExxonMobil has been steadily increasing its position in west Texas and specifically cited strong Lower Spraberry results as one of the drivers for recently acquiring an additional 48,000 Midland Basin acres in August 2015.
