CALGARY, Feb. 25, 2013 /CNW/ - SilverWillow Energy Corporation ("SilverWillow" or the "Corporation") is pleased to announce an increase to its estimate of Discovered Petroleum Initially-In-Place and the assignment of Contingent Resources following an independent evaluation of the bitumen resources attributable to its oil sands property, the Audet Lands, located approximately 110 km northeast of Fort McMurray, Alberta.

"We are pleased to advise that the estimate of Discovered Petroleum Initially-In-Place has increased from 1,689.6 million barrels to 1,845.9 million barrels following Sproule's review of the results from the 2012 drilling program", announced Howard Lutley, President and Chief Executive Officer of SilverWillow.  "Furthermore, of the above Discovered Resources, Sproule has assigned a best estimate of Contingent Resources to the Audet Lands of 68.4 million barrels of recoverable bitumen in place.  This independent confirmation of the potential within the Audet Lands gives us added confidence as we advance the project."

Sproule Unconventional Limited ("Sproule") prepared the independent evaluation of the bitumen resources of the Audet Lands in the Athabasca Oil Sands region of Alberta for SilverWillow effective December 31, 2012.  Sproule's work on the Audet Lands included a geological evaluation and an engineering review of the work conducted by SilverWillow's independent consultants with respect to caprock integrity tests and reservoir simulation studies to determine the potential for production of bitumen using Steam Assisted Gravity Drainage ("SAGD") methods.

SilverWillow is currently engaged in the engineering design of a pilot and a commercial project. It is, therefore, premature to evaluate the economic viability of the project at this time, and the economic status of the contingent resources assigned to SilverWillow's Audet Lands is undetermined.

In early 2012 SilverBirch Energy Corporation ("SilverBirch"), the prior holder of the Audet Lands, completed an exploration drilling program consisting of 38 core holes, 2D seismic, mini-frac tests and geo-mechanical testing.  The 2012 program was a follow-up to the 34 core holes drilled on the Audet Lands in 2011 by SilverBirch. These leases, which are now owned 100% by SilverWillow, are located 110 km northeast of Fort McMurray, and approximately 40 km north of Cenovus Energy Inc.'s proposed Telephone Lake project.

During 2012, SilverWillow engaged geo-mechanical engineering and reservoir engineering consultants to assist the Corporation in the assessment of the Audet Lands for the production of bitumen by SAGD methods.  The results of the technical work by the consultants indicate that the reservoir and caprock properties will allow production by SAGD methods at appropriate pressures without compromising the integrity of the caprock.  Additional studies will be undertaken to properly assess the areal extent of the caprock properties and the requirement for a small-scale pilot to demonstrate the integrity of the caprock under operating conditions.  SilverWillow will acquire additional caprock data in its 2013 exploration program and is in the process of determining the cost of a small caprock pilot test for the Audet Lands. This will provide important field data regarding performance of the caprock, and will assist in the design of SilverWillow's proposed 12,000 barrel per day SAGD development project.

1The term "contingent resources" is taken from the Canadian Oil and Gas Evaluation Handbook ("COGEH") as published by the Society of Petroleum Evaluation Engineers (Calgary Chapter).  The volumes listed in the chart above entitled, "Contingent Bitumen Resources" refer to potentially recoverable volumes of bitumen resources. The volumes of contingent bitumen resources in the above chart are presented in millions of barrels at stock tank conditions.  There is no certainty that it will be commercially viable to produce any portion of the contingent bitumen resources.

SilverWillow has updated its investor presentation to reflect this announcement.  The presentation is posted on SilverWillow's website at www.swenergy.ca.

Methodology

The preparation and disclosure of the reported resource estimates are the responsibility of SilverWillow's management and require approval by the Corporation's Reserves and HSE Committee and Board of Directors.  Sproule's responsibility is to express an opinion on the contingent bitumen resources based on the data provided by management.  Sproule carried out the evaluation and review in accordance with standards established by National Instrument 51-101 Standards of Disclosure for Oil and Gas Activities.  These standards require that the contingent resources estimates be prepared in accordance with COGEH.

Discovered Petroleum Initially-In-Place (equivalent to Discovered Resources) is defined in COGEH as that quantity of petroleum that is estimated, as of a given date, to be contained in known accumulations prior to production. The recoverable portion of discovered petroleum initially-in-place includes production, reserves, and contingent resources; the remainder is unrecoverable.

Contingent Resources are defined in COGEH as 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 project stage.

With respect to the Contingent Resources associated with SilverWillow's Audet Lands, the contingencies which prevent the classification of these resources as reserves are as follows: the need for a pilot to verify the effectiveness of the McMurray Formation shales as caprock for steam containment during the SAGD operation; the absence of regulatory approvals for future commercial development; the absence of a firm commercial development plan; and the uncertainty of funding approval for commercial developments.

Contingent Resources do not constitute and should not be confused with reserves.  There is no certainty that it will be commercially viable to produce any portion of the contingent resources on any of the above mentioned properties.
