      Company was incorporated in October 2003 in the State of&#xd;
      Nevada and has established its corporate offices in Shawnee,&#xd;
      Oklahoma.&amp;#160;&amp;#160;On February&amp;#160;27, 2006, the Company&#xd;
      changed its name from Ingenium Capital Corp. to Nitro&#xd;
      Petroleum Incorporated.&amp;#160;&amp;#160;The Company is engaged&#xd;
      primarily in the acquisition, development, production,&#xd;
      exploration for, and the sale of oil, gas and natural gas&#xd;
      liquids.&amp;#160;&amp;#160;All business activities are conducted in&#xd;
      Texas and Oklahoma and the Company sells its oil and gas to a&#xd;
      limited number of domestic purchasers.&lt;/font&gt;&#xd;

      financial statements have been prepared in accordance with&#xd;
      generally accepted accounting principles applicable to a&#xd;
      going concern, which assumes that the Company will be able to&#xd;
      meet its obligations and continue its operations for its next&#xd;
      twelve months.&amp;#160;&amp;#160;Realization values may be&#xd;

      these financial statements do not give effect to adjustments&#xd;
      that would be necessary to the carrying values and&#xd;
      classification of assets and liabilities should the Company&#xd;
      be unable to continue as a going concern.&amp;#160;&amp;#160;As of&#xd;
      April 30, 2013, the Company has not achieved profitable&#xd;
      operations. The Company has accumulated losses of $6,536,314&#xd;
      since its inception, has a working capital deficiency of&#xd;
      $480,591 and expects to incur further losses in the&#xd;
      development of its business, all of which casts substantial&#xd;
      doubt about the Company&amp;#8217;s ability to continue as a&#xd;
      going concern.&amp;#160;&amp;#160;The Company&amp;#8217;s ability to&#xd;
      continue as a going concern is dependent upon its ability to&#xd;
      generate future profitable operations and/or to obtain the&#xd;
      necessary financing to meet its obligations and repay its&#xd;
      liabilities arising from normal business operations when they&#xd;
      come due.&amp;#160;&amp;#160;Management has no formal plan in place&#xd;
      to address this concern but considers that the Company will&#xd;
      be able to obtain additional funds by equity financing and/or&#xd;
      related-party advances; however there is no assurance of&#xd;
      additional funding being available.&lt;/font&gt;&#xd;
