NuVista Energy Ltd. Announces Fourth Quarter and Year End 2012 Results

NuVista Energy Ltd. Announces Fourth Quarter and Year End 2012 Results 
CALGARY, ALBERTA -- (Marketwire) -- 03/06/13 -- NuVista Energy Ltd.
("NuVista") (TSX:NVA) is pleased to announce results for the three
and twelve months ended December 31, 2012 and provide an update on
its future business plans. 2012 was a pivotal and successful year for
NuVista as the business model was transformed in this challenging
natural gas price environment. In our year end 2011 press release we
indicated we would be carefully evaluating our business to preserve
value and ensure a sustainable model without jeopardizing our
financial flexibility. We also indicated a focus on proving the
valuable long term growth opportunities in the Wapiti Montney play,
and that we would pursue dispositions of non-strategic assets
throughout 2012 where attractive values could be realized and
financial flexibility enhanced. We are pleased to report that we have
delivered on these commitments. Through asset sales and strong Wapiti
drilling results we have transformed NuVista into a company focused
on its large and valuable condensate-rich Wapiti Montney play. We
have also reduced long-term debt, net of working capital, from $307
million at December 31, 2011 to $30 million at December 31, 2012,
enabling us to adequately capitalize this world class play. 
NuVista now has the improved asset quality and financial flexibility
to provide the foundation for a growth focused business model and the
creation of long-term shareholder value. Heading into 2013 the next
key steps in our Wapiti Montney-focused strategy are as follows: 

--  To deliver a repeatable Wapiti area Montney focused development program
    of production growth, continuing to drive the capital and operating
    efficiencies of scale into this play; 
--  To put in place long term processing infrastructure commitments
    underpinning this growth; 
--  To continue to delineate our reserve and contingent resource base in the
    upper layer of the Montney across the rest of our landholdings and into
    the deeper layers including the so-far under-evaluated Lower Montney; 
--  To execute an opportunistic non-core divestiture program in the range of
    $25 million to $50 million where it enhances our financial flexibility;
--  To mainta
in flexibility in our capital spending programs to ensure we
    can dial upwards or downwards as we monitor balance sheet strength, play
    results, and the fiscal environment. 

The business environment continued to be challenging for all energy
producers in 2012. AECO natural gas prices fell to a 14 year low
annual average price of $2.28/GJ down 35% from 2011. This decline was
primarily due to over supply of natural gas in the face of an
unusually warm winter. In addition, heavy oil prices were down 9% and
Edmonton light prices were down 4% compared to 2011 due to larger
discounts to WTI crude oil. Low heating demand and supply imbalance
have caused propane and butane benchmark prices to drop by 43% and
14% respectively in 2012 versus 2011. Only condensate (pentanes+)
maintained excellent pricing in Western Canada, averaging $100.86/Bbl
in 2012 (107% of WTI) versus $104.19/Bbl in 2011 on the back of
continued strong demand outstripping local supply due to increasing
oilsands bitumen blending needs. Due to continued oilsands growth in
the province, condensate price strength is expected to continue in
the long term, underpinning the strength of NuVista's Wapiti Montney
play in which strong economics are dominated by condensate revenues. 
NuVista is pleased to announce the appointment of two new directors
to its Board, effective March 5, 2013: Mr. Ron Eckhardt and Mr.
Sheldon Steeves. Both leaders have significant experience in various
aspects of the upstream oil and gas business and we welcome their
contributions as we move forward. In addition, Mr. Clayton Woitas has
informed the Board of Directors that he will not be standing for
re-election at the next Annual General Meeting in May 2013 due to
other commitments. The Board of Directors and staff of NuVista would
like to thank Mr. Woitas for his many years of dedicated leadership
and guidance as a Board member. 
Significant highlights for the fourth quarter and full year 2012

--  Completed the disposition of non-strategic assets in the fourth quarter
    of $228 million and for the full year totaling $238 million; 
--  Completed equity offerings for gross proceeds of $95 million on December
    11, 2012 with strong support from several existing and new strategic
    institutional investors; 
--  Achieved our guidance with an average production rate of 17,692 Boe/d
    for the three months ended December 31, 2012 and 22,577 Boe/d for the
    year ended December 31, 2012 compared to 25,306 Boe/d for the three
    months ended December 31, 2011 and 25,556 Boe/d for the year ended
    December 31, 2011. These production rates reflect the significant
    dispositions in the fourth quarter of 2012 and lower capital spending
    levels in 2012; 
--  Achieved funds from operations of $16.3 million for the three months
    ended December 31, 2012 compared to $48.5 million for the same period in
    2011 and $17.2 million for the three months ended September 30, 2012.
    Funds from operations for the full year 2012 totaled $75.7 million
    compared to $164.0 million in 2011. Lower funds from operations in 2012
    were primarily due to a decline in average realized natural gas prices
    from $3.87/Mcf in 2011 to $2.31/Mcf in 2012 and lower production volumes
    in 2012 due to divestitures; 
--  Successfully executed an annual capital program of $117 million. Drilled
    4 (3.0 net) wells during the fourth quarter and 18 (14.2 net) wells for
    the year ended December 31, 2012 for a success rate of 94%. 6 (5.9 net)
    of these wells were Wapiti Montney wells and the remainder of the wells
    were primarily W3/W4 heavy oil wells drilled in the first quarter of
--  Achieved proved plus probable finding and development costs for 2013 of
    $15.53/Boe including future development capital and all revisions with
    debt adjusted reserves growth of 8% per share. Achieved a proved plus
    probable reserves replacement ratio (excluding divested property
    production) of 315%, and increased our proved plus probable Reserves
    Life Index ("RLI") to 16 years; 
--  Increased our rolling hedging program to manage commodity exposure, with
    45% of 2013 oil and liquids production (net of royalties) hedged with an
    average WTI floor price of $91.30/Bbl and 38% of 2013 natural gas
    production (net of royalties) hedged at an average AECO floor price of
    approximately $3.00/Mcf; and 
--  Exited 2012 with net debt of $30 million and a trailing 12 month debt to
    annualized fourth quarter funds from operations of 0.4x, a significant
    improvement compared to $307 million and 1.9x at the end of 2011. 

Wapiti Montney Play Proven and Set to Grow 
During 2012 NuVista significantly advanced its Wapiti Montney play,
and coupled with industry results in the greater Wapiti and Resthaven
Montney area has confirmed the presence of a large condensate-rich
resource. We have moved up from one to an average of two rigs
drilling the Montney entering 2013. In 2013, approximately 80% of
NuVista's capital budget will be allocated to the Wapiti Montney play
and strong results are expected to have a continued significant and
positive impact on NuVista's overall corporate performance even in
the curren
t natural gas price environment. The premium priced
condensate production is the key economic driver of this play. During
early 2013, NuVista expects to enter into transportation and
processing agreements that will permit NuVista to provide greater
clarity on its future capital and growth plans. 
In the third quarter of 2012, NuVista completed its $70 million five
well and facilities pilot program. Based on the positive results from
these wells NuVista continued with its Montney drilling program and
this play has become the prime focus of NuVista's future growth and
value creation initiatives. NuVista owns Montney rights on 192 (176
net) sections concentrated in the greater Wapiti area after having
added 16% more lands to our block in the past year. At December 31,
2012, NuVista had five wells on production, each for a period of at
least four months, with average production on track with our 4.4 Bcf
raw (5.2 Bcfe) forecast typecurve with the valuable condensate
component of this production at 46 Bbls/MMcf (raw), exceeding our
typecurve of 35 Bbls/MMcf. Total C3+ liquids have averaged 59
Bbls/MMcf versus our typecurve expectation of 50 Bbls/MMcf. 
In September of 2012, NuVista conducted an independent study,
assigning contingent resource to the Middle Montney formation on
approximately 79 sections, or about 45% of its landholdings. The
assigned resource totaled 200 MMBoe (Best estimate), including 45
MMBoe of condensate with a resource net present value before tax,
discounted at 10% of $1.25 billion based on evaluator price forecasts
at that time. Details of this resource evaluation were disclosed in
NuVista's press release dated November 7, 2012. Our independently
evaluated 2012 year end reserves report highlights that significant
momentum is also building with NuVista's Wapiti Montney reserves.
Montney proved reserves increased to 15.7 MMBoe from 5.1 MMBoe and
proved plus probable reserves increased to 29.2 MMBoe from 12.1 MMBoe
on a year over year basis. At December 31, 2012, only 42 Wapiti
Montney wells have been included in NuVista's proved plus probable
reserves report. As shown in the reserves section of this document,
the 2012 Wapiti Montney activity almost offset the impact of
dispositions in the fourth quarter despite drilling with only one
Since our last quarterly press release on November 7, 2012, NuVista
has completed and recently brought its sixth Middle Montney well onto
production. We have two more wells which have been successfully
fractured and completed with testing underway. They are expected to
be tied-in and on production in late March or early April of 2013
subject to spring break-up conditions. One fracture completion was
delayed due to a mechanical downhole equipment failure and we are
currently in the middle of remedial action. Completions and tie-ins
continue and we expect to be reporting several more 30-day initial
production results in our first quarter 2013 press release. We will
continue to update actual production versus typecurve as additional
production data is achieved. NuVista has noted industry data on at
least five wells with up to a year's production data which indicate
larger fracture treatments provide sustained results which support a
typecurve increase of 50% or more. Due to this and our technical
analysis, we are planning larger fracture treatments for early 2013.  
NuVista has drilled two vertical wells near the southwest and
northeast extremities of our Montney land blocks in order to acquire
logs and core samples towards evaluation of the upper and lower
Montney zones. This moves the resource evaluation outwards and
deeper. One of these wells is currently being completed in the lowest
Montney zone as we continue to lay the groundwork of proving the
deeper layers of the Montney formation. 
Impairment in Value of Oil and Gas Properties 
NuVista recognized a fourth quarter impairment to the value of
Property, Plant and Equipment and Goodwill in the amount of $70.5
million. These impairments are primarily due to economic revisions
associated with lower oil and natural gas price forecasts used in
reserves evaluation and secondarily due to technical reserve
revisions. For the year ended December 31, 2012, NuVista recognized
impairments to the value of Property, Plant and Equipment and
Goodwill totaling $218.5 million. The impairments are described in
more detail in NuVista's audited financial statements and
management's discussion and analysis for the year ended December 31,
2012, available through NuVista's filings on SEDAR at  
2013 Guidance 
In 2013, NuVista is taking a measured approach to its capital and
operating programs. NuVista expects to produce in the range of 15,250
Boe/d to 16,250 Boe/d in the first half of 2013, with the growth
benefits of the Montney program beginning to kick-in post breakup
with fourth quarter 2013 guidance of 17,500 Boe/d to 18,500 Boe/d
depending on second half capital spending. We expect to average two
rigs in the Montney formation in 2013, but have front-loaded our
capital in the first and second quarter of 2012 with prelaid
infrastructure and a temporary third rig, in order to best work
around spring break-up. As a result, first half 2013 spending is
anticipated to be approximately $110 million followed by reduction in
the second half of 2013. We have the flexibility to increase or
decrease this average annualized rig count of two subject to balance
sheet monitoring, dispositions, the commodity environment, ongoing
results, and infrastructure announcements. We will also continue our
focus on opportunistic asset divestitures, with a full year 2013
target of $25 million to $50 million in divestiture proceeds. 
We remain excited about the tremendous condensate-rich potential of
our Montney play at Wapiti, and the continued growth and exceptional
value that will be created as we build our scale and the efficiencies
that come with it.

       cash flow from operating activities as per the statement of cash     
       flows before changes in non-cash working capital and asset retirement
       expenditures. Funds from operations per share is calculated based on 
       the weighted average number of common shares outstanding consistent  
       with the calculation of net earnings (loss) per share. Funds from    
       operations netback equals the total of revenues including realized

2012 Year End Reserves Highlights 
Our 2012 independent engineering evaluation has been completed by GLJ
Petroleum Consultants Ltd. ("GLJ") effective December 31, 2012 (the
"GLJ Report").  
2012 year end proved reserves were 59.2 MMBoe compared to 69.5 MMBoe
at year end 2011. Proved plus probable year end reserves were 94.1
MMBoe compared to 109.7 MMBoe at year end 2011. NuVista's proved and
proved plus probable reserve additions (net of revisions) of 13.5
MMBoe and 19.1 MMBoe (over 90% Montney) respectively were offset by
reductions from the 2012 asset dispositions totaling 15.6 MMBoe of
proved reserves and 26.5 MMBoe of proved plus probable reserves. Also
included were negative proved plus probable revisions of 4.5 MMBoe,
83% of which were economic revisions due to reduced price forecasts.
Overall finding and development costs, including revisions and future
development capital, were $19.17/Boe for proved reserves and
$15.53/Boe for proved plu
s probable reserves. This resulted in a
corporate proved plus probable operating netback recycle ratio of
0.9. The corporate recycle ratio reflects the lower average operating
netback of our current production mix at low gas prices and is not
reflective of the economics of our Montney focused reserve additions
in 2012.  
2012 Wapiti Montney play specific proved plus probable finding and
development costs were $13.16/Boe. Fourth quarter operating netbacks
were $18.75/Boe which result in a play recycle ratio of 1.4x despite
the challenging natural gas price environment and high one-time
operating costs from midstream processors where a once-in-5-year
turnaround was completed. The Wapiti Montney play recycle ratio is
expected to increase significantly in 2013 (absent of commodity price
changes) as drilling and completion costs are reduced and operating
costs and netbacks are optimized through scale. The Wapiti Montney
recycle ratio and expectations for further improvements are one of
the many factors that provide us with the confidence to focus on this
play and its ability to create long-term growth and shareholder
Other highlights of our reserve report include a proved plus probable
RLI of 16.1 years, and a proved plus probable reserves replacement
ratio (excluding divested property production) of 315% (based on
fourth quarter 2012 production excluding divested properties).

This news release contains the terms barrels of oil equivalent
("Boe") and thousand cubic feet equivalent ("Mcfe"). Natural gas is
converted to a Boe using six thousand cubic feet of gas to one barrel
of oil. In certain circumstances natural gas liquid volumes have been
converted to a Mcfe on the basis of one barrel of natural gas liquids
to six thousand cubic feet of gas. Boes and Mcfes may be misleading,
particularly if used in isolation. The foregoing conversion ratios
are 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

In this press release, NuVista has disclosed the results of an
evaluation of the contingent resources associated with the Middle
Montney formation of NuVista's Wapiti Montney play. The contingent
resource evaluation was prepared by GLJ, NuVista's independent
qualified reserves evaluator, in accordance with NI 51-101 and the
Canadian Oil and Gas Evaluation Handbook and is effective September
1, 2012. 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. The contingencies may
include factors such as economics, legal, environmental, political
and regulatory matters or lack of markets. A best estimate is the
estimate of the quantity of resource that will be recovered from the
accumulation, which under probabilistic methodology reflects a 50
percent confidence level. A low estimate is the estimate of the
quantity of resource that will be recovered from the accumulation,
which under probabilistic methodology reflects a 90 percent
confidence level. A high estimate is the estimate of the quantity of
resource that will be recovered from the accumulation, which under
probabilistic methodology reflects a 10 percent confidence level.
Contingent resources are further classified in accordance with the
level of certainty associated with the estimates. 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. The contingent resources as
disclosed herein are considered economic based on forecast prices and
costs as at September 1, 2012. The majority of the 200 MMBoe best
estimate of the contingent resources associated with the Middle
Montney is represented by natural gas; however, 28.5% (56.8 MMBoe) of
the best estimate is represented by natural gas liquids including
44.5 MMBoe of which is classified as condensate. Additional
information relating to the contingent resources estimate for the
Middle Montney formation of NuVista's Wapiti Montney play, including
specific contingencies and significant positive and negative factors
associated with the estimate, can be found in NuVista's November 7,
2012 press release, which can be accessed on SEDAR (
