Petro River Oil Provides Update on Woodburn Forest-1 Well in Larne Basin, Northern Ireland

NEW YORK, NY --(Marketwired - June 17, 2016) - Petro River Oil Corp (OTCBB: PTRC) ("Petro River" or the "Company") announced today that drilling has been completed at the Woodburn Forest-1 well in Larne Basin, Northern Ireland.

The well was drilled to a depth of 2,000 meters and encountered two conventional, porous sandstone reservoir intervals, the Triassic Sherwood and the Permian Collyhurst. As previously disclosed, our original objective was to reach the Carboniferous source rock at this depth, however the Permian section thickened considerably and the Carboniferous was not reached. A majority of the well participants supported drilling deeper, however several of the other well participants declined, and the decision was made to plug and abandon the well. Although our joint venture partners decided not to drill to the Carboniferous, we are encouraged by findings of thermogenic gas in the Collyhurst section. The presence of thermogenic gas supports our original assessment of the existence of hydrocarbon source rock in the Carboniferous and a viable petroleum system.

The Company will now work with our partners to incorporate the data from the Woodburn Forest-1 well into our basinal interpretation and focus on our next phase of development. Jamie Rector, Petro River's Chief Geological Advisor, stated, "The Woodburn Forest-1 well confirmed a primary objective of showing the presence of thermogenic gas. Structural complexity, the absence of well control and modern seismic did not allow us to optimize the well location. Our next steps include reprocessing the existing 2D seismic in the offshore block and acquiring new seismic."

"We made an incremental step in the right direction," said Petro River president Stephen Brunner. "While we were unable to drill the well to the original target of the Carboniferous, the discovery of thermogenic gas is promising. We are encouraged and are moving forward in our efforts to explore the Larne Basin."
