Chinook Energy Inc. ("Chinook" or the "Company") (TSX:CKE) today announced the
results of its year-end reserve evaluations effective December 31, 2011 as
prepared by its independent evaluators. The Company has also provided certain
unaudited year end financial information and an update to previously provided
guidance for 2012 resulting from adjustments to the capital program in response
to natural gas prices and asset dispositions.


Chinook's audit of its 2011 annual consolidated financial statements is not yet
complete and accordingly all financial amounts referred to in this news release
are unaudited and represent management's estimates. Readers are advised that
these financial estimates are subject to audit and may be subject to change as a
result. 


2011 Reserves Highlights 

Three evaluators, which were largely responsible for the previous evaluations of
the same assets, have evaluated all of Chinook's crude oil, NGL and natural gas
reserves in accordance with National Instrument 51-101. Chinook's Reserves
Committee and Board of Directors have reviewed and approved the evaluations
prepared by the evaluators. Highlights of such evaluations are as follows:




--  Proved reserves totaled 32.2 million barrels of oil equivalent. The
    proved reserve life index ("RLI") is 5.8 years using fourth quarter 2011
    production. 
--  Proved plus probable reserves totaled 55.8 million barrels of oil
    equivalent. The proved plus probable RLI is 10 years using fourth
    quarter 2011 production. 
--  Proved plus Probable reserves are down 11% from 2010. Assets
    representing 6.7% of the 2010 reserves were sold during the year and
    Economic Factors and Technical Revisions represented a 5.8% decline from
    2010 reserve levels. 2011 reserve additions from drilling exceeded
    production by 15%. 
--  The proved finding and development cost, as per NI 51-101 requirements,
    was $54.45 per barrel of oil equivalent and the proved plus probable
    finding and development cost, as per NI 51-101 requirements, was $54.53
    per barrel of oil equivalent. The change in future development costs
    ("FDC") and revisions were included in the calculation and the effect of
    acquisitions and divestitures was excluded. 
--  The net asset value amounted to $773.5 million which results in the
    estimated net asset value per basic share (214.2 million shares) at
    December 31, 2011, being $3.61 per share based on the net present value
    of proved and probable reserves, discounted at 10% after tax and after
    deducting year end total net debt and adding an estimated value for
    undeveloped land in Canada. On a before tax basis, with a similar 10%
    discount rate, the net asset value is $1.1 billion or $5.03 per basic
    share. 
--  Commodity prices used in the independent evaluation were down
    approximately 13% for natural gas which represents 49% of the corporate
    reserve volumes and up approximately 11% for the slate of liquids which
    represent 51% of the corporate reserve volumes. 
--  The present value of reserves, and the NAV per share, was largely
    unchanged from 2010 as the decrease in reserve volumes and natural gas
    pricing attributable to the natural gas-weighted assets in Canada was
    offset almost entirely by increased value in the Tunisian oil-weighted
    assets. 
--  Gross Discovered Petroleum Initially in Place ("DPIIP") associated with
    the Bir Ben Tartar (TT) discovery on the Sud Remada permit in Tunisia,
    after the addition of five development wells in 2011, is estimated to be
    153.7 million barrels of oil. Proven and probable reserves net to the
    Company of 3.4 million barrels of oil represents the Company's 46%
    Contractor's share of the 7.3 million barrels of oil remaining
    recoverable. Proven and probable reserves have been assigned to areas
    representing 40% of the DPIIP up to a 13 percent recovery, or an average
    of 5% recovery for the entire structure. An additional 2.0 million
    barrels of oil of possible reserves and a Best Case Contingent Resource
    of 6.8 million barrels net to the Company's interest is attributable to
    the DPIIP area to which 2P reserves have not been assigned up to the
    date of evaluation. Possible reserves are those additional reserves that
    are less certain to be recovered than probable reserves. There is a 10%
    probability that the quantities actually recovered will exceed the sum
    of proved plus probable reserves. On this basis, 28% of the reserve and
    resource potential recognized on the block is reflected in the Company's
    NI 51-101 reserves and net asset value. The net present value after tax
    discounted at 10% for the proved plus probable reserves is $139 million
    or $41.00 per barrel. 
--  The Company established a recycle ratio on a proven plus probable
    reserve basis, before commodity price contracts, and using NI 51-101
    finding and development costs, of 0.4 times in Canada and 0.8 times in
    Tunisia. 
--  Chinook has 28 gross sections of Bitumen rights in the Portage/Thornbury
    area of NE Alberta proximal to pilot projects being initiated by other
    operators. An initial evaluation of the Company's bitumen assets has
    identified Best Case Company Share of Exploitable Bitumen in Place of
    271 mboe and Best Case Contingent Resource of 102.6 mboe in the McMurray
    and Grande Rapids Formations net to the Company's 74.55% working
    interest. 



2011 Operational Highlights and Unaudited Full Year Results

Chinook's average daily production for fiscal 2011 was 14,602 barrels of oil
equivalent per day. Production for the last half of 2011 was 14,780 barrels of
oil equivalent per day and for the fourth quarter was 15,118 barrels of oil
equivalent per day. Projected cash flow from operations (before changes in
non-cash working capital) for 2011 is estimated at $84.9 million or $0.40 per
weighted average basic common share outstanding (unaudited). Year end 2011 net
debt is $135 million.


The Canadian business focused on crude oil project development in the core areas
of West Central Alberta and Grande Prairie and the sale of non-core assets to
improve the ratio of growth assets in the remaining domestic asset base and
improve the boe meterics. The Tunisian business focused on the conversion of
probable reserves to proven producing and an initial ramp up in production at
the Bir Ben Tartar discovery. Tunisian production grew 150% and 2011 was the
Company's most active year ever against a backdrop of the Arab spring
revolution, a year of civil unrest, and the introduction of a new political
system. The corporate drilling program consisted of 43 (26.84 net) wells of
which 34 were operated and 9 were non-operated wells. The results are outlined
in the table below:

Revised Guidance

As a result of the continuing downward pressure on the North American natural
gas price and the completion of two disposition transactions, it is appropriate
to revise the guidance for 2012 from the initial 2012 budget which was prepared
in November 2011. 


On the basis of current natural gas prices not covering fixed and variable costs
and an adequate return on the depletion of certain assets, the Company has shut
in a large portion of its Northeast Alberta shallow dry natural gas production
which represents approximately 430 boe/d included in the initial 2012 forecast.
In addition, given current AECO spot prices, the natural gas price used in the
forecast has been adjusted from $3.74/mcf to $2.70/mcf.


Given the near term forecast for natural gas prices the Company has deferred
approximately $10 million worth of capital from the Canadian capital program
with an effect of eliminating approximately 225 boe/d of volumes previously
included in the 2012 forecast. 


On February 15, 2012, Chinook closed the previously announced disposition of its
Manyberries property, located in southeastern Alberta, to the City of Medicine
Hat for consideration of approximately $36.2 million. Chinook has also reached
an agreement to sell a package of unit interests for $20 million, subject to
normal closing adjustments, with an expected closing date of March 15, 2012.
Chinook's current bank debt subsequent to the closing of the Manyberries
property disposition is $101 million. The Company intends to use the proceeds
from the disposition of the unit interests to further reduce debt such that it
expects debt to be approximately $80 million after the completion of the sale,
prior to factoring in Q1 2012 capital expenditures which are expected to exceed
quarterly cash flow by $15-20 million. The production adjustment to previous
2012 guidance as a result of these two 2012 transactions, and two transactions
that closed in December 2011 (after previous guidance was released) is an
average reduction of 830 boe/d.


The Company will also reduce the capital program in Tunisia by $15 million in an
attempt to better manage the balance sheet early in the year. This will be
accomplished with an expected one quarter delay in the commencement of the
central facility and pipeline projects but will not effect forecast production.

Notes:                                                                      

1.  Revised guidance is based on: AECO gas price of $2.70/mcf; Edmonton
    light oil price of $96.20/bbl (CDN); Brent oil price of $104.00/bbl
    (CAD); 55% natural gas production; 45% liquids. 
2.  Previous guidance was based on: AECO gas price of $3.74/mcf; Edmonton
    light oil price of $95.00/bbl (CDN); Brent oil price of $104.00/bbl
    (CAD); 55% natural gas production; 45% liquids. 



Asset sales and natural gas price related technical revisions were key
contributors to decreasing reserves in Canada. The increased value of the light
oil assets in Tunisia supported the Net Asset Value being unchanged from year
end 2010. Chinook's balance sheet is in very good shape and able to support the
forecast capital program of 1.3 times cash flow which will be focused on
developing Chinook's Brent priced oil production in Tunisia. In Canada, the
Company will continue to work to improve the netbacks of its domestic natural
gas weighted production, focus capital on oil prospects, and dispose of assets
as it has successfully done over the last 15 months.

Benchmark oil and NGL prices used are adjusted for quality of oil or NGL

deduction for estimated future well abandonment but does not include a      
provision for interest, debt service charges and general and administrative 
expenses. It should not be assumed that the NPV estimated represents the

The after-tax NPV of Chinook's oil and natural gas properties reflects the  
tax burden on the properties on a stand-alone basis and does not consider   
the business-entity-level tax situation, or tax planning. It does not       
provide an estimate of the value at the level of the business entity, which 
may be significantly different. The financial statements and the            
management's discussion and analysis ("MD&A") of Chinook should be consulted
for information at the level of the business entity.

Future Development Costs ("FDC")    

NI 51-101 requires that future development costs be calculated including changes
in FDC. Changes in forecast FDC occur annually as a result of development
activities, acquisition and disposition activities and capital cost estimates
that reflect the independent evaluators' best estimate of what it will cost to
bring the proved undeveloped and probable reserves on production.

Recycle Ratio

The recycle ratio is calculated as the fourth quarter netback per barrel divided
by the finding and development costs (excluding acquisitions and dispositions,
abandonment and furniture and fixtures). It is a measure of the profitability
and efficiency of the Company.

Corporate Net Asset Value

The Company's net asset value as of December 31, 2011, is detailed in the
following table. This net asset value determination is a "point-in-time"
measurement and does not take into account the possibility of Chinook being able
to recognize additional reserves through successful future capital investment in
its existing properties beyond those included in the 2011 year-end reserve
reports.

Bir Ben Tartar - Discovered Petroleum Initially-in-Place

Insite assigned 153.7 million barrels of Discovered Petroleum Initially-In-Place
to the Bir Ben Tartar (TT) discovery.


DPIIP is the quantity of petroleum that is estimated, as of a given date, to be
contained in known accumulations prior to production. The recoverable portion of
DPIIP is divided into commercial (reserves), and sub-commercial (Contingent
Resources); the remainder is by definition unrecoverable. 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 in respect of the Bir Ben Tartar (TT) discovery that prevent such
Contingent Resources to be classified as reserves include the lack of a
reasonable expectation that all internal and external approvals will be
forthcoming to fully develop the asset, further reservoir studies, delineation
drilling, facility design, preparation of firm development plans and regulatory
applications. Other commercial considerations that may preclude the
classification of contingent resources as reserves include factors such as
legal, environmental, political and regulatory matters or a lack of markets.
Estimates of DPIIP and Contingent Resources described herein are estimates only;
the actual resources may be higher or lower than those calculated in Insite's
report. There is no certainty that it will be commercially viable to produce any
portion of the resources described herein.


The most significant positive and negative factors with respect to the
Contingent Resource estimates in respect of the Bir Ben Tartar (TT) discovery
relate to fact that the field is currently at an evaluation/delineation stage.


The table below summarizes the DPIIP, Reserves, Cumulative Production,
Contingent Resources and portion of the unrecoverable portion of DPIIP
associated with the Bir Ben Tartar (TT) discovery.

Alberta Oil Sands - Exploitable Bitumen in Place

The table below reflects the Company's Contingent Bitumen Resources as of
December 31, 2011, as evaluated by McDaniel reflected the Company's 74.55%
working interest in its oil sands leases in the Portage and Thornbury areas of
Alberta.


Actual resources may be greater than or less than the estimates provided herein.
Contingent Resources can be sub-classified into economic and uneconomic factors
based on a number of assumptions such as capital costs, timing, price forecasts
and other considerations. Currently sub-classification of these estimates has
not been completed pending a determination of the above parameters. The
contingencies which currently prevent the classification of the Contingent
Resources disclosed in the tables below as reserves consist of: further
reservoir studies, delineation drilling, facility design, preparation of firm
development plans, regulatory applications and corporate approvals. There is no
certainty that it will be commercially viable for the Corporation to produce any
portion of the Contingent Resources on any of its properties. The most
significant positive and negative factors with respect to the Contingent
Resource estimates relates to the fact that property is currently at an
evaluation/delineation stage.


The information provided hereunder for Thornbury is based on an evaluation
conducted by McDaniel effective December 31, 2011.  The information provided
hereunder for Portage is based on an evaluation conducted by McDaniel effective
June 1, 2010. McDaniel carried out the evaluations in accordance with standards
established by the Canadian Securities Administrators in NI 51-101.

About Chinook Energy Inc.

Chinook is a Calgary-based public oil and gas exploration and development
company that combines high quality natural gas-weighted assets in Western Canada
with an exciting high growth oil business onshore and offshore Tunisia in North
Africa.


Definitions of Oil and Gas Resources and Reserves

Reserves are estimated remaining quantities of oil and natural gas and related
substance 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.


Possible Reserves are those additional reserves that are less certain to be
recovered than probable reserves. It is unlikely that the actual remaining
quantities recovered will exceed the sum of the estimated proved plus probable
plus possible reserves. There is 10% probability that the quantities recovered
will exceed the sum of proved and probable reserves.


Resources encompasses all petroleum quantities that originally existed on or
within the earth's crust in naturally occurring accumulations, including
Discovered and Undiscovered (recoverable and unrecoverable) plus quantities
already produced. "Total resources" is equivalent to "Total Petroleum
Initially-In-Place". Resources are classified in the following categories:


Discovered Petroleum Initially-In-Place ("DPIIP") is 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 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.


Unrecoverable is that portion of DPIIP and UPIIP quantities which is estimated,
as of a given date, not to be recoverable by future development projects. A
portion of these quantities may become recoverable in the future as commercial
circumstances change or technological developments occur; the remaining portion
may never be recovered due to the physical/chemical constraints represented by
subsurface interaction of fluids and reservoir rocks.


Uncertainty Ranges are described by the COGE Handbook as low, best, and high
estimates for reserves and resources as follows:


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 a 90 percent probability (P90) 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 (P50) that the quantities 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 will exceed the high estimate. If probabilistic methods are used,
there should be at least a 10 percent probability (P10) that the quantities
actually recovered will equal or exceed the high estimate.


Reader Advisory

Forward-Looking Statements

In the interest of providing shareholders and potential investors with
information regarding Chinook, including management's assessment of the future
plans and operations of Chinook, certain statements contained in this news
release constitute forward-looking statements or information (collectively
"forward-looking statements") within the meaning of applicable securities
legislation. Forward-looking statements are typically identified by words such
as "anticipate", "continue", "estimate", "expect", "forecast", "may", "will",
"project", "could", "plan", "intend", "should", "believe", "outlook",
"potential", "target" and similar words suggesting future events or future
performance. In addition, statements relating to "reserves" are deemed to be
forward-looking statements as they involve the implied assessment, based on
certain estimates and assumptions, that the reserves described exist in the
quantities predicted or estimated and can be profitably produced in the future.
In particular, this news release contains, without limitation, forward-looking
statements pertaining to: the recognition of significant additional reserves
under the heading "2011 Independent Reserve Evaluation"; the volumes and
estimated value of Chinook's oil and natural gas reserves; the life of Chinook's
reserves; the volume and product mix of Chinook's oil and natural gas
production; future oil and natural gas prices and Chinook's commodity risk
management program; future results from operations and operating metrics; and
future development, exploration, acquisition and development activities
(including drilling plans) and related production expectations as well as
management's future expectations set out under the heading "Revised Guidance". 


With respect to the forward-looking statements contained in this news release,
Chinook has made assumptions regarding, among other things: that Chinook will
continue to conduct its operations in a manner consistent with past operations,
the ability of Chinook to continue to operate in Tunisia with limited logistical
security and operational issues, future capital expenditure levels, future oil
and natural gas prices, future oil and natural gas production levels, Chinook's
ability to obtain equipment in a timely manner to carry out development
activities, the impact of increasing competition, the ability of Chinook to add
production and reserves through development and exploitation activities, certain
commodity price and other cost assumptions, the continued availability of
adequate debt and equity financing and cash flow to fund its planned
expenditures. Although Chinook believes that the expectations reflected in the
forward-looking statements contained in this news release, and the assumptions
on which such forward-looking statements are made, are reasonable, there can be
no assurance that such expectations will prove to be correct. Readers are
cautioned not to place undue reliance on forward-looking statements included in
this news release, as there can be no assurance that the plans, intentions or
expectations upon which the forward-looking statements are based will occur. By
their nature, forward-looking statements involve numerous assumptions, known and
unknown risks and uncertainties that contribute to the possibility that
predictions, forecasts, projections and other forward-looking statements will
not occur, which may cause Chinook's actual performance and financial results in
future periods to differ materially from any estimates or projections of future
performance or results expressed or implied by such forward-looking statements.
These risks and uncertainties include, without limitation, political and
security risk associated with Chinook's Tunisian operations, risks associated
with oil and gas exploration, development, exploitation, production, marketing
and transportation, loss of markets, volatility of commodity prices, currency
fluctuations, imprecision of reserve and resource estimates, the continued
impact of shut-in production, environmental risks, competition from other
producers, inability to retain drilling rigs and other services, capital
expenditure costs, including drilling, completion and facilities costs,
unexpected decline rates in wells, delays in projects and/or operations
resulting from surface conditions, wells not performing as expected, delays
resulting from or inability to obtain the required regulatory approvals and
ability to access sufficient capital from internal and external sources. 

As a consequence, actual results may differ materially from those anticipated in
the forward-looking statements. Readers are cautioned that the forgoing list of
factors is not exhaustive. Additional information on these and other factors
that could effect Chinook's operations and financial results are included in
reports on file with Canadian securities regulatory authorities and may be
accessed through the SEDAR website (www.sedar.com) and at Chinook's website
(www.chinookenergyinc.com). Furthermore, the forward-looking statements
contained in this news release are made as at the date of this news release and
Chinook does not undertake any obligation to update publicly or to revise any of
the forward-looking statements, whether as a result of new information, future
events or otherwise, except as may be required by applicable securities laws.


Barrels of Oil Equivalent

Barrels of oil equivalent (boe) is calculated using the conversion factor of 6
mcf (thousand cubic feet) of natural gas being equivalent to one barrel of oil.
Boes may be misleading, particularly if used in isolation. A boe conversion
ratio of 6 mcf:1 bbl (barrel) 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.


Reserve Life Index

The reader is also cautioned that this news release contains the term reserve
life index ("RLI"), which is not a recognized measure under GAAP. Management
believes that this measure is a useful supplemental measure of the length of
time the reserves would be produced over at the rate used in the calculation.
Readers are cautioned, however, that this measure should not be construed as an
alternative to other terms determined in accordance with IFRS as a measure of
performance. Chinook's method of calculating this measure may differ from other
companies, and accordingly, they may not be comparable to measures used by other
companies.


Operating Netback

The reader is also cautioned that this news release contains the term operating
netback, which is not a recognized measure under GAAP and is calculated as a
period's sales of petroleum and natural gas, net of royalties less net
production and operating expenses as divided by the period's sales volumes.
Management uses this measure to assist them in understanding Chinook's
profitability relative to current commodity prices and it provides an analysis
tool to benchmark changes in operational performance against prior periods and
to peers on a comparable basis. Readers are cautioned, however, that this
measure should not be construed as an alternative to other terms such as net
income determined in accordance with IFRS as a measure of performance. Chinook's
method of calculating this measure may differ from other companies, and
accordingly, they may not be comparable to measures used by other companies.


Cash flow from operations

The reader is also cautioned that this news release contains the term cash flow
from operations, which is not a recognized measure under GAAP and is calculated
from cash flow from continuing operations adjusted for changes in non-cash
working capital. Management believes that cash flow is a key measure to assess
the ability of Chinook to finance capital expenditures and debt repayments.
Readers are cautioned, however, that this measure should not be construed as an
alternative to other terms such as cash flow from operating activities, net
income or other measures of financial performance calculated in accordance with
IFRS. Chinook's method of calculating this measure may differ from other
companies, and accordingly, they may not be comparable to measures used by other
companies.
