Company And Summary Of Significant Accounting Policies Policies
Oil and Gas Properties	The Company follows the successful efforts method of accounting for its oil and natural gas properties. Oil and gas properties are periodically assessed to determine whether they have been impaired. Any impairment in value of unproved properties is charged to exploration expense. The costs of unproved properties, which are determined to be productive, are transferred to prove oil and gas properties and amortized on an equivalent unit-of-production basis. Exploratory expenses, including geological and geophysical expenses and delay rentals for unevaluated oil and gas properties, are charged to expense as incurred. Exploratory drilling costs are initially capitalized as unproved property but charged to expense if and when the well is determined not to have found proved oil and gas reserves. In accordance with ASC No. 935, exploratory drilling costs are evaluated within a one-year period after the completion of drilling. For proved properties, we compare expected undiscounted future cash flows at a producing field level to the unamortized capitalized cost of the asset. If the future undiscounted cash flows, based on our estimate of future natural gas and crude oil prices, operating costs, anticipated production from proved reserves and other relevant date, are lower than the unamortized capitalized cost, the capitalized cost is reduced to fair value. Fair value is calculated by discounting the future cash flows at an appropriate risk-adjusted discount rate. During the six months ended April 30, 2015 and 2014, the Company impaired its oil and gas properties by $269,906 and $2,219,813, which is reflected in the consolidated statement of operations. The Company recorded income in the six months ended April 30, 2014 of $1,760,392 in connection with the transfer of some of the Company’s interest in three wells to PIE Holdings, LP. This income is included in the income statements as other income.
Going Concern	As shown in the accompanying consolidated financial statements, the Company has incurred an accumulated deficit of $36,264,801 through April 30, 2015. In addition, the Company had a working capital deficit of $5,191,782 and cash and cash equivalents of $222,779 at April 30, 2015. The current rate of cash usage raises substantial doubt about the Company’s ability to continue as a going concern, absent the raising of additional capital, restructuring or extending the terms on its current debt and/or additional significant revenues from new oil production. The Company’s financial statements do not include any adjustments relating to the recoverability and classification of recorded assets, or the amounts and classification of liabilities that might be necessary in the event that the Company cannot continue in existence.

Disclosure of accounting policy for reporting when there is a substantial doubt about an entity's ability to continue as a going concern for a reasonable period of time (generally a year from the balance sheet date). Disclose: (a) pertinent conditions and events giving rise to the assessment of substantial doubt about the entity's ability to continue as a going concern for a reasonable period of time, (b) the possible effects of such conditions and events, (c) management's evaluation of the significance of those conditions and events and any mitigating factors, (d) possible discontinuance of operations, (e) management's plans (including relevant prospective financial information), and (f) information about the recoverability or classification of recorded asset amounts or the amounts or classification of liabilities. If management's plans alleviate the substantial doubt about the entity's ability to continue as a going concern, disclosure of the principal conditions and events that initially raised the substantial doubt about the entity's ability to continue as a going concern would be expected to be considered. Disclose whether operations for the current or prior years generated sufficient cash to cover current obligations, whether waivers were obtained from creditors relating to the company's default under the provisions of debt agreements and possible effects of such conditions and events, such as: whether there is a possible need to obtain additional financing (debt or equity) or to liquidate certain holdings to offset future cash flow deficiencies. Disclose appropriate parent company information when parent is dependent upon remittances from subsidiaries to satisfy its obligations.
