Petro River Reports 175% Increase in Proved Reserves and 1,053% Increase in Production

Projects Positive Net Cash Flow for Next Quarter and Doubles Down on 2018 Development Plans

NEW YORK, NY / ACCESSWIRE / June 20, 2018 / Petro River Oil Corp. (OTC PINK: PTRC) (''Petro River'' or the ''Company''), is an independent oil and gas exploration company that utilizes 3D seismic technology to discover and develop oil & gas reserves in proven oil & gas basins. Petro River is pleased to present recent field results and its oil and gas reserves, as evaluated May 1, 2018, by independent engineering firm, Cawley, Gillespie & Associates.

Recent Corporate Highlights

• Proved reserves as of May 1, 2018 show 175% increase from the reserve report issued on May 1, 2017.

• BOE production increases 1,053% for fiscal year April 30, 2018 from April 30, 2017 period.

• In May 2018, the Company completed its initial ten well exploration and development program of the West Blackland field in Osage County, Oklahoma. The wells were drilled to a depth of approximately 2,850 feet, and their results are expected to move Petro River into positive cash flow in the quarter ended July 31, 2018. Several wells encountered a combination of both Mississippian Chat and Burgess ''pay,'' which has resulted in increased production rates.

• Before year-end 2018, the Company plans to drill 13 additional wells, which would more than double its current well count. The Company currently anticipates that projected cash flow will be sufficient to fund the drilling expenses for the pending wells.
  
  
• The 2018 drilling program will include:

• Drilling of as many as ten development wells in the new North Blackland field discovered by the Blackland #2-34 well spud on April 15, 2018, and confirmed by the successful completion of the Blackland #2-35 well spud on May 16, 2018.

• Drilling of three exploration wells to test the 2,000-acre Arsaga structure and 650-acre Section 13 structure identified by the Company's 3D seismic data. If successful, these structures could yield a repeatable and scalable drilling program of as many as 130 wells in 2019 and beyond (based on 20 acres spacing per well).

• The Company's initial exploration program achieved a success rate exceeding 78% utilizing its current 3D seismic.
