Athabasca Oil Corporation reports a significant increase in bitumen contingent resources and light oil reserves, and assigns 51 million barrels of proved reserves at Hangingstone

CALGARY, March 28, 2013 /CNW/ - Athabasca Oil Corporation (TSX: ATH) announces that it has filed its Annual Information Form dated March 28, 2013, which can be retrieved electronically from the Company's website (www.atha.com) or from SEDAR (www.sedar.com).

Athabasca is also pleased to report the highlights of an independent reserves and resources evaluation, conducted by GLJ Petroleum Consultants Ltd. and DeGolyer MacNaughton Canada Limited, of the Company's thermal and light oil assets, at December 31, 2012.

Highlights include:

• Reclassification of 51 million barrels ("bbl") of Hangingstone's probable bitumen reserves to the proved reserve category, based upon receipt of regulatory approvals and project sanctioning by the Company's Board of Directors;
  
  
• Contingent bitumen resources (best estimate) increased, year-over-year, by approximately eight percent to 10.6 billion bbl of bitumen;
  
  
• Proved plus probable bitumen reserves increased over the previous year's estimate of 339 million bbl of bitumen (net of the disposition of the MacKay River Joint Venture), to an estimated 342 million bbl; and
  
  
• Light oil reserves increased by approximately 139 percent, year-over-year, from 9.2 million barrels of oil equivalent ("boe") of proved plus probable reserves to 22.0 million boe proved of plus probable reserves.
  
  

Thermal Oil Division

In 2012, Athabasca received regulatory approvals to construct the Hangingstone Project 1, a 12,000 bbl/d SAGD project. The Company's Board of Directors subsequently sanctioned the Hangingstone Project 1, triggering the reclassification of 51 million bbl of Hangingstone's probable reserves to the proved reserve category, effective December 31, 2012.

The Hangingstone project area is comprised of 136,000 acres of oil sands leases which, based upon an independent engineering estimate, at December 31, 2012, contain 51 million bbl of proved reserves, 66 million bbl of probable reserves and 0.9 billion bbl of contingent resources (best estimate).

Year-over-year additions to the Thermal Oil Division's reserves and resources reflect the successful results of the 2011-2012 Winter Drilling and Seismic Program which further delineated the bitumen deposits.

In March 2012, Athabasca closed the sale of its remaining 40-percent interest in the MacKay River Joint Venture to Cretaceous Oilsands Holdings Limited, which subsequently amalgamated with Phoenix Energy Holdings Limited, a wholly-owned subsidiary of PetroChina Company International Limited. The sale resulted in the divestiture of a combined 114 million bbl of proved plus probable reserves and 573 million bbl (best estimate) of contingent resources.

At Dover West, Athabasca acquired oil sands leases which contained approximately 1.0 billion bbl of contingent resources (best estimate), at December 31, 2012.

Light Oil Division

At December 31, 2012, the Light Oil Division's reserves increased, year-over-year, from 9.2 million boe of proved plus probable ("2P") reserves to 22.0 million boe proved plus probable reserves. This 139-percent, year-over-year increase in Athabasca's 2P reserves reflects a successful drilling and completion program in 2012 which targeted stacked (or multi-zone) unconventional reservoirs in the Duvernay and Montney formations.

At year-end, the Light Oil Division had established production from 33 horizontal wells in the Fox Creek area (Kaybob East, Kaybob West and Saxon/Placid). Production facilities were commissioned in late 2012, limiting the reporting period for well production histories. Artificial lift has now been installed on the majority of the new wells, which is expected to stabilize production rates.

As production trends and type curves are established in 2013, the Company expects to prove reservoir recoveries and additional 2P reserves. Additional wells were drilled in late 2012, but were not completed or tested prior to year-end - production from these new wells is expected to contribute additional 2P reserves in 2013. At year end 2012, Athabasca had just 30 percent of its proven light oil reserves classified as Proven Undeveloped (PUD) locations.

Athabasca's strategy has been to secure egress and maximized net backs for its product. As such, the Company invested a significant amount to construct wholly owned infrastructure in the Kaybob and Simonette areas during 2012, thereby reducing future costs, on a boe basis, as production increases. The control of infrastructure is expected to provide the Company with the flexibility to blend and market crude oil and condensate, according to market demands, thereby increasing net backs. Athabasca's 2012 capital program of $611 million included approximately $189 million for facilities and $27 million for the acquisition of petroleum and natural gas leases. The Company's 2013 capital budget includes an additional $38 million to construct the infrastructure associated with year-end 2P reserves.

Athabasca expects to realize future cost reductions as it moves down the learning curve, primarily through the drilling of multi-wells from single pads. By leveraging its fixed operating costs - along with the ability to blend oil with Duvernay condensate - the Company expects to receive a premium netback for its product. These factors should provide for a very competitive finding and development and recycle ratio for future development plans at Fox Creek.

Light Oil Reserves at December 31, 2012
	Reserves (millions of barrels of oil equivalent)
	Proved	Probable	Proved + Probable
Kaybob	8.3	6.7	15.0
Saxon Placid	2.7	4.0	6.7
Exploration Area	0.2	0.1	0.3
Total	11.2	10.8	22.0

Athabasca's resources and reserves are situated within a land base that is comprised of greater than 1.5 million acres (net) of oil sands leases and permits held by the Thermal Light Oil Division and greater than 2.8 million acres (net) of petroleum and natural gas leases held by the Light Oil Division. During the past year, the Company's combined Thermal Oil and Light Oil land base increased by approximately 19 percent, from 3.6 to approximately 4.3 million acres (net).

In addition, information and statements in this News Release relating to "reserves" and "resources" are deemed to be forward-looking information, as they involve the implied assessment, based on certain estimates and assumptions, that the reserves and resources described exist in the quantities predicted or estimated, and that the reserves and resources described can be profitably produced in the future. The assumptions relating to the Company's  reserves and resources are contained in the reports of GLJ Petroleum Consultants Ltd. and DeGolyer and MacNaughton Canada Limited, each dated effective December 31, 2012. For additional information regarding the specific contingencies which prevent the classification of the Company's Contingent Resources as Reserves see "Independent Reserve and Resource Evaluations - Contingent Resources Estimates" in the AIF. The estimates of reserves and future net revenue for individual properties in this New Release may not reflect the same confidence level as estimates of reserves and future net revenue for all properties, due to the effects of aggregation. "Contingent Resources" has the meaning given to that term in the AIF.

The forward-looking statements included in this News Release are expressly qualified by this cautionary statement. Athabasca does not undertake any obligation to publicly update or revise any forward-looking statements except as required by applicable securities laws.

Oil and Gas Information:
"BOEs" may be misleading, particularly if used in isolation.  A BOE conversion ratio of six thousand cubic feet of natural gas to one barrel of oil equivalent (6 Mcf: 1 bbl) is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead.
