CALGARY, March 11, 2014 /CNW/ - Advantage Oil & Gas Ltd. ("Advantage" or the "Corporation") is pleased to report strong year end 2013 reserve additions for its Montney resource property at Glacier, Alberta ("Glacier").  Proven plus probable ("2P") reserve additions were achieved at a finding and development cost of $1.33/mcfe ($7.99/boe) and a recycle ratio of 2.1.  Total 2P reserves are up 20% to 1.7 trillion cubic feet ("Tcfe").  We are also pleased to report Glacier production reached our 135 mmcfe/d Phase VI target ahead of schedule with capital spending below budget.        

Advantage's year-end 2013 corporate reserves which will include the impact of non-core asset divestures during 2013 will be released on March 27, 2014 with its year-end financial and operating results.  All references to year end 2013 financial and operating data in this release are estimates and are unaudited.

Glacier 2013 Reserve Report Summary

• Advantage replaced 840% of Glacier's 2013 annual production based on Sproule's 2013 Glacier reserve report⁽¹⁾⁽²⁾.
  
• Glacier reserve additions were achieved at a proven and probable ("2P") Finding & Development ("F&D") cost including the change in Future Development Capital ("FDC") as follows:

• Sproule's 2013 Glacier reserve report demonstrates the continued and efficient conversion of identified natural gas and liquids resources at Glacier into 2P reserves. In comparison to the Sproule 2012 Glacier reserve report, the increase in reserves are indicated below by category:
• Glacier's 2P reserves increased by 20% to 1.70 Tcfe (282.6 mmboe). Natural gas liquids 2P reserves increased 393% to 13.0 mmbbls.
• Proven reserves increased by 17% to 1.03 Tcfe (172.3 mmboe) and now represents 61% of total Glacier 2P reserves
• Proven developed producing reserves increased by 18% to 0.21 Tcfe (34.8 mmboe)
• The recycle ratio associated with our Glacier 2P F&D cost based on Advantage's Q4 2013 estimated operating netback at Glacier is indicated in the following table:

• The total number of future well locations booked and the estimated ultimate recoverable ("EUR") gas per well assigned by Sproule in their 2013 Glacier reserve report are illustrated in the following table:

• A total of 415 developed and undeveloped locations are booked in Sproule's 2013 Glacier reserve report which is an increase of 55 locations compared to Sproule's 2012 Glacier reserve report.  The additional locations resulted from recognition of wells that were drilled during 2013 and undeveloped locations which were primarily assigned in the Middle Montney on lands offsetting new wells. 
• The average 2P EUR assignments per well were increased from 4.7 bcf/well to 5.4 bcf/well for future undeveloped Upper Montney locations and from 5.0 bcf/well to 5.1 bcf/well for future undeveloped Lower Montney locations. The Middle Montney future undeveloped locations were assigned an average 2P EUR of 3.7 bcf/well, which was unchanged, compared to 2012.  This was due to the relatively short amount of production history from the existing six Middle Montney wells and only three new Middle Montney wells drilled in 2013.
• Technical revisions accounted for 25% of the 2P reserve additions in 2013.  These revisions, which did not require any increase to FDC, can be attributed to improved well test results and solid production performance from wells in which modified completion techniques were applied in 2012 and 2013.
• Advantage estimates a total well inventory of 1,416 locations at Glacier based on our current drilling pattern of four wells per section in each of the five Montney development layers.  Based on the Sproule 2013 Glacier reserve report which has 415 locations booked, over 1,000 locations remained unbooked. 
• Glacier's proven reserve life index is 26.2 years and its 2P reserve life index is 43 years based on its average fourth quarter 2013 production rate of 108.1 mmcfe/d.
• Sproule's 2P Glacier forecast of operating income for the five year period of 2014 to 2018 is $1.51 billion which exceeds Sproule's scheduled capital expenditures by $0.74 billion.    
• The 2P Net Present Value determined by Sproule increased by 49% to $2.1 billion as at December 31, 2013 (10% discount factor on a pre-tax basis).

Glacier Production Reaches 135 mmcfe/d Phase VI Target Ahead of Schedule with Capital Spending Below Budget

• Strong well results from our current drilling program and solid long term production from existing wells contributed to achieving Advantage's Phase VI Glacier production target of 135 mmcfe/d in early March 2014 which is approximately one month ahead of our Phase VI Budget schedule.
• We anticipate Q1 2014 Glacier production will average between 122 mmcfe/d to 126 mmcfe/d as a result of the higher current production rate in March.  Minor plant outages were required during Q1 2014 to accommodate construction work and integration of new well facility pads.    
• Nine new wells from Advantage's Glacier Phase VI program have been brought on production to initially ramp production to 135 mmcfe/d.  The remaining 13 new wells from our Phase VI program are expected to provide sufficient production inventory to maintain production at 135 mmcfe/d through to the end of 2014. To date, all planned 22 wells in our Phase VI program have been rig released.  New well completions and tie-ins of Phase VI wells will continue through Q2 2014.
• As a direct comparison to our original Glacier Phase VI capital budget, we now forecast total Phase VI program expenditures to be approximately $151 million which is lower than our budget by approximately $13 million.  The reduced capital spending resulted from lower than budgeted well costs due to efficiencies attained through improved drilling times and more streamlined well completion procedures.
• The reduced capital spending amount of approximately $13 million was redirected to purchase 43.25 net sections of additional Montney lands in Q3 2013 for $6.8 million and to accelerate our Glacier Phase VII program with plans to drill four new wells in March 2014.  We will continue with Phase VII drilling through spring break-up and are scheduling new Phase VII wells to be brought on production in early 2015 leading to attainment of our Phase VII production target of 183 mmcfe/d in Q2 2015.

Strong Reserve Replacement Efficiencies & Production Performance Reinforces Advantage's Glacier Three Year Development Plan

• Sproule's December 31, 2013 Glacier reserves report provides additional confirmation on the quality of Advantage's Montney asset through the achievement of strong reserve replacement efficiencies.
• Glacier's three year 2P F&D cost of $1.06/mcfe combined with a three year recycle ratio of 2.7 provides a solid foundation and track record in support of Advantage's recently announced Glacier three year development plan (see Advantage press release dated February 4, 2014).
• Advantage's Glacier three year development plan is expected to increase production per share by 100% and increase cash flow per share by 190% with an average total debt to forward cash flow ratio of approximately 1.5 at an average natural gas price of Cdn $3.75/GJ.  Our financial strategy includes natural gas commodity hedges on 44% of forecasted production at an average price of Cdn $3.84/mcf to Q1 2016 and a strengthened balance sheet to complement our development plan.
• Achievement of Advantage's Glacier Phase VI production target ahead of schedule with lower than budgeted capital expenditures demonstrates our strong operational expertise and execution skills which underpin our three year development plan.
• Drilling rigs have been secured to initiate our three year development plan which will begin with our Glacier Phase VII program during Q2 2014.
• The Glacier Phase VII Capital and Operating Budget was approved by our Board of Directors on February 4, 2014 with the following guidance:

Reserve Definitions

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

Proved Reserves are those reserves that can be estimated with a high degree of certainty to be recoverable. It is likely that the actual remaining quantities recovered will exceed the estimated proved reserves.

Probable Reserves are those additional reserves that are less certain to be recovered than proved reserves. It is equally likely that the actual remaining quantities recovered will be greater or less than the sum of the estimated proved plus probable reserves.

Barrels of oil equivalent (boe) and thousand cubic feet of natural gas equivalent (mcfe) may be misleading, particularly if used in isolation. Boe and mcfe conversion ratios have been calculated using a conversion rate of six thousand cubic feet of natural gas equivalent to one barrel of oil. A boe and mcfe conversion ratio of 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. Given that the value ratio based on the current price of crude oil as compared to natural gas is significantly different from the energy equivalency of 6:1, utilizing a conversion on a 6:1 basis may be misleading as an indication of value.
