HOUSTON, TEXAS - December 4, 2012 (Investorideas.com energy newswire) EFL Overseas Inc. (OTCBB:EFLO) is pleased to announce the acquisition of additional working interests in the Kotaneelee gas property and the results of independent reserves and resources evaluations (NI-51-101 compliant).

SUMMARY OF RESOURCES

The following reports certain pro forma resource information, based on an independent assessment by AJM dated effective June 30, 2012 using forecast prices and costs (the "EFLO AJM Resource Report"). The EFLO AJM Resource Report was prepared in accordance with definitions, standards and procedures contained in the COGE Handbook and NI 51-101.

 

The AJM Resource report evanuated the resources on EFLO acreage on gross terms and did not consider working interest. AJM evaluated the lands to assess the resource potential for the Middle Devonian Shales designated as Lower Black Shale (Muskwa/Evie), Middle Shale (Fort Simpson), and Upper Shale (Kotcho/Exshaw) as well as the potential for expansion of resource for the Nahanni on the producing East Flank. The results are summarized as follows, adjusted by management to reflect EFLO's 53.65% interest in the evaluated lands after giving effect to the Devon and Nahanni acquisitions.

Disclosure in this document of reserves and resources is presented in accordance with Canadian securities laws. The United States Securities and Exchange Commission (the "SEC") generally permits U.S. reporting oil and gas companies, in their filings with the SEC, to disclose only proved, probable and possible reserves and production, net of royalties and interests of others. The Company uses certain terms in this document, such as resources or contingent resources that the SEC's rules would prohibit a U.S. company from including in filings with the SEC. The SEC generally does not permit U.S. companies to disclose net present value of future net revenue from reserves based on forecast prices and costs. Canadian securities laws permit, among other things, the presentation of certain categories of resources and the disclosure of production on a gross basis before deducting royalties. Unless noted otherwise, all disclosures of reserves and resources in this document are made on a gross basis using forecast price and cost assumptions.

In this news release:

"gross" means:

(a) in relation to the Company's interest in production or reserves, its working interest share before deduction of royalties;

(b) in relation to wells, the total number of wells in which the Company has an interest; and

(c) in relation to properties, the total area of properties in which the Company has an interest.

"net" means:

(a) in relation to the Company's interest in production or reserves, its working interest share after deduction of royalty obligations;

(b) in relation to the Company's interest in wells, the number of wells obtained by aggregating the Company's working interest in each of its gross wells; and

(c) in relation to the Company's interest in a property, the total area of properties in which the Company has an interest multiplied by the working interest owned by the Company.

All evaluations of future revenue are after the deduction of royalties, development costs, production costs and well abandonment costs but before consideration of indirect costs such as administrative, overhead and other miscellaneous expenses.

Disclosure of Reserves

The reserves estimates and related estimates of net present values presented in this document were prepared to comply with Canadian reserves disclosure standards and reserves definitions as set out in NI 51-101 and the COGE Handbook prepared jointly by The Society of Petroleum Evaluation Engineers (Calgary Chapter) and the Canadian Institute of Mining, Metallurgy & Petroleum (Petroleum Society).

Reserves are estimated remaining quantities of oil and natural gas and related substances anticipated to be recoverable from known accumulations, from a given date forward, based on:

    analysis of drilling, geological, geophysical and engineering data;

    the use of established technology; and

    specified economic conditions, which are generally accepted as being reasonable.

Reserves are classified according to the degree of certainty associated with the estimates:

Disclosure of Resources

In this news release, the Company also refers to estimates of "contingent resources". These estimates represent the best estimate of the contingent resources attributed to the Company's interest, are not classified or recognized as reserves, and are in addition to the Company's disclosed reserve volumes.

Contingent resources are those quantities of petroleum estimated, as of a given date, to be potentially recoverable from known accumulations using established technology or technology under development, but which are not currently considered to be commercially recoverable due to one or more contingencies. Contingencies may include factors such as economic, legal, environmental, political, and regulatory matters, or a lack of markets. It is also appropriate to classify as contingent resources the estimated discovered recoverable quantities associated with a project in the early evaluation stage. There is no certainty that it will be commercially viable to produce any portion of the contingent resources and the estimated future net revenues do not necessarily represent the fair market value of such contingent resources.

The Company's resources classified as contingent resources, rather than as reserves, are so classified pending the need for further facility design, preparation of firm development plans and regulatory applications (including associated reservoir studies and delineation drilling) and corporate approvals to proceed with development.

When evaluating contingent resources, the following mutually exclusive categories are recommended in the COGE Handbook:

    Low Estimate: This is considered to be a conservative estimate of the quantity that will actually be recovered. It is likely that the actual remaining quantities recovered will exceed the low estimate. If probabilistic methods are used, there should be at least 90 percent probability that the quantities actually recovered will equal or exceed the low estimate.

    Best Estimate: This is considered to be the best estimate of the quantity that will actually be recovered. It is equally likely that the actual remaining quantities recovered will be greater or less than the best estimate. If probabilistic methods are used, there should be at least a 50 percent probability that the quantity actually recovered will equal or exceed the best estimate.

    High Estimate: This is considered to be an optimistic estimate of the quantity that will actually be recovered. It is unlikely that the actual remaining quantities recovered will exceed the high estimate. If probabilistic methods are used, there should be at least a 10 percent probability that the quantities actually recovered will equal or exceed the high estimate.

FORWARD-LOOKING STATEMENTS

This news release includes forward-looking statements, including but not limited to estimates of reserves and resources and the present value of revenues associated with such reserves and resources. Statements in this news release relating to reserves and resources involve the implied assessment, based on certain estimates and assumptions, that the described reserves and resources, as the case may be, exist in the quantities predicted or estimated, and can be profitably produced in the future. There is no assurance that the forecast price and cost assumptions contained in the AJM reports will be realized and variances could be material. Other assumptions and qualifications relating to project schedules, costs and other matters are inherent in these estimates.

In addition, all statements other than statements of historical facts, included in this news release that address activities, events, or developments that the Company believes or anticipates will or may occur in the future are forward-looking statements, including but not limited to the Company's intent to pursue the acquisition of additional interest in the Kotaneelee property, the Company's planned exploration activities and the existence of potential opportunities in the Pacific Rim, North America and the Yukon. Such forward-looking statements involve known and unknown risks, uncertainties and other factors, which may cause the actual results, performance or achievements expressed or implied by such forward-looking statements. Such factors include general economic and business conditions, the ability to acquire and develop specific projects and reach commercially acceptable terms with counterparties, the ability to secure government and other third party approval, potential third party claims, the ability to fund operations, and other factors over which the Company has little or no control. The Company does not intend to update publicly any forward-looking statements, except as may be required by law. There can be no assurance that EFLO will be successful in completing the acquisition of additional interest(s) in the Kotaneelee properties or executing its planned exploration and development activities.

The contents of this news release should be considered in conjunction with the warnings and cautionary statement contained in the Company's public filings, which are accessible on SEDAR at www.sedar.com.
