Organization, Consolidation and Presentation of Financial Statements [Abstract]
Going Concern and Management’s Plan:	The accompanying condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. As of January 31, 2015, the Company had a stockholders’ deficiency of $15,185,307. The Company has not generated any significant revenues from ongoing operations and incurred net losses since inception. These matters raise substantial doubt about the Company’s ability to continue as a going concern. The condensed consolidated financial statements do not include any adjustments relating to the recoverability and classification of asset amounts or the classification of liabilities that might be necessary should the Company be unable to continue as a going concern. The Company’s primary source of operating funds since inception has been equity financings. The Company is currently focused on developing its core position in the Mississippi Lime, specifically in the Pearsonia West Concession in Osage County recently acquired during the Bandolier Acquisition and Bandolier’s acquisition of Spyglass. Management’s current plans in the Mississippi Lime play are focused on Pearsonia West, but Petro River also owns additional Mississippi Lime acreage in Kansas. Over the last 12 months the Company has continued to build out its leadership and technical team with individuals with extensive experience in the Mississippi Lime play. Additionally, the Company has been in discussions with industry partners to capitalize and develop additional acreage in the Mississippi Lime. The Company continues to seek out joint venture partners and acquisition targets. The Company continues to evaluate its non-core projects related to its legacy heavy oil reservoirs. While still in technical review, the Company is engaged in a series of pilot tests related to certain theories, technologies and processes on the Missouri heavy oil assets. In Missouri, the Company has continued to analyze reservoir data and testing results to determine if any of these technologies or processes may lead to a viable and economic development plan for the understanding and test phases to develop an economic heavy oil production reserve base. The Company is leveraging executive vice president Luis Vierma’s experience in heavy oil, which he acquired during his time as Vice President of Exploration and Production at Petrуleos de Venezuela, S.A. Management’s principal objective is to maximize shareholder value by, among other things, increasing production by developing its acreage, increasing profit margins by evaluating and optimizing its production, and executing its business plan to increase property values, prove its reserves, and expand its asset base. In addition, management is focused on developing Petro Spring, its technology focused business, which recently acquired Havelide Assets and Coalthane Assets. While management currently has no plans to discontinue or revise its business plan, recent volatility and decrease in crude oil prices may cause management to cut back on its development or acquisition plans, or otherwise revisit its business and/or its capital expenditure plan. Continued volatility and decreases in crude oil prices may accelerate such cut back or revisions. To combat price volatility in crude oil process and further diversify the business, management has increased its focus on the development of Petro Spring. At January 31, 2015, the Company had working capital of approximately $1.1 million. As a result of the utilization of cash in its operating activities, and the development of its assets, the Company has incurred losses since it commenced operations. In addition, Petro has a limited operating history prior to acquisition of Bandolier. At January 31, 2015, the Company had cash and cash equivalents of approximately $1.5 million. While management believes that the current level of working capital is sufficient to maintain current operations in Kansas, Oklahoma and Missouri as well as the planned added operations for the next twelve months, additional capital will be necessary for management to execute its business plan, develop the Havelide and Coalthane Assets, and to further expand the Company’s exploration and development programs beyond such period. To address the Company’s working capital requirements and execute its business plan, management intends to continue to raise capital through the issuance of debt and equity securities. In addition, and to address the recent volatility and decreases in crude oil prices, the Company has initiated cost-cutting measures commencing November 1, 2014. No assurances can be provided that the Company will be successful in its efforts to raise additional required capital, which efforts may be more difficult given the recent volatility and decrease in the price of crude oil. Furthermore, inability to maintain capital may damage the Company’s reputation and credibility with industry participants. The Company’s inability to raise additional funds when required may have a negative impact on its consolidated results of operations and financial condition.
