WESTERN OIL SANDS
INTERIM REPORT FOR THE SIX-MONTH PERIOD ENDED JUNE 30, 2006


MESSAGE TO SHAREHOLDERS
- -------------------------------------------------------------------------------

Western  Oil Sands Inc.  ("Western")  announced  its  operating  and  financial
results for the second quarter of 2006.  Western generated net revenue of $95.6
million, an EBITDAX loss of $8.2 million, negative cash flow from operations of
$20.9  million  ($0.13 per share)  and a net loss of $22.8  million  ($0.14 per
share).  By  comparison,  in the second quarter of 2005,  Western  recorded net
revenue of $148.2 million,  EBITDAX of $84.1 million, cash flow from operations
of $68.0 million ($0.42 per share) and net earnings of $28.7 million ($0.18 per
share).

     Excluding the impact of risk  management and foreign  exchange losses each
net of tax,  the net loss for the second  quarter of 2006 would have equated to
$13.1  million  compared to net  earnings  of $41.6  million for the prior year
period.  Relative to the second quarter of 2005,  financial  results during the
second  quarter of 2006 were  significantly  impacted by the loss of production
and the one-time expenses associated with the first major planned turnaround at
the Muskeg River Mine and the Scotford  Upgrader,  partially offset by a 33 per
cent increase in West Texas Intermediate  ("WTI") prices, no volumes subject to
hedge  contracts  and a 36 per cent  narrowing  of the  heavy  crude  oil price
differentials  from 41 per cent to 26 per  cent of WTI  prices.  In the  second
quarter of 2006,  our net loss included a $27.3 million  ($24.0  million net of
tax)  unrealized  foreign  exchange  gain  and an  unrealized  risk  management
(mark-to-market)  loss


                      SECOND QUARTER INTERIM REPORT 2006  WESTERN OIL SANDS   1


of $44.5 million ($33.7  million net of tax) compared to an unrealized  foreign
exchange  loss of $7.2  million  ($6.0  million net of tax) with no  unrealized
mark-to-market adjustments for the second quarter of 2005.

HIGHLIGHTS

o    During  the  second  quarter  of 2006,  the  Athabasca  Oil Sands  Project
     ("AOSP") undertook its first major turnaround, commencing in May with full
     production  resuming  in  mid-July.  Following  the initial  cleaning  and
     inspection of the equipment, it was determined that additional maintenance
     and repair work at the  Scotford  Upgrader was required in order to remove
     large  amounts  of coke  from the  reactor  vessels  at the  Upgrader  and
     complete other work to enhance long-term  performance.  Consequently,  the
     turnaround   schedule  was  extended   beyond  the  previously   announced
     eight-week  duration.  As a result  of this  full  turnaround,  production
     during the quarter averaged 15,540 barrels per day net to Western compared
     to 32,757  barrels  per day net to Western  in the second  quarter of 2005
     (non-turnaround quarter). Significantly lower production during the second
     quarter of 2006,  combined  with the  associated  expenses  incurred  as a
     result of the  turnaround,  resulted  in  operating  costs of  $62.50  per
     processed  barrel.  When the AOSP operated at full  production  during the
     month of April, operating costs per processed barrel, excluding turnaround
     costs were  $21.75.  As a result of the  turnaround,  quarter-over-quarter
     comparisons in terms of production and operating  costs per barrel are not
     meaningful.

o    As  announced  on  May  30,  2006,  Western's   wholly-owned   subsidiary,
     WesternZagros Limited,  entered into an Exploration and Production Sharing
     Agreement  (EPSA) with the  Kurdistan  Regional  Government,  Sulaymaniyah
     Administration  to explore  for  conventional  oil and gas in the  Federal
     Region of Kurdistan in northern Iraq.  This  opportunity  is  particularly
     attractive to Western because it requires a modest capital investment over
     the initial  period of the EPSA,  while  offering  the  potential of large
     long-life  reserves with a low cost structure.  This agreement will become
     effective  when it is passed  into law which is  expected  to occur in the
     coming months.  Under the terms of the EPSA,  WesternZagros will undertake
     an  exploration  program  over a 3,700  square  kilometre  block that will
     involve  geophysical  and  geological  studies  followed by an exploratory
     drilling program.  The minimum  contractual  commitment under the terms of
     the EPSA is US$45  million over the first four years.  Should  exploration
     prove successful,  additional exploration and development expenditures are
     anticipated.

o    Subsequent  to the end of the  second  quarter,  in  early  July,  Western
     announced that over the past year, the AOSP initiated a detailed review of
     the  proposed  Expansion  1.  Although  not yet  complete,  there are very
     significant  upward pressures on capital costs of the project.  One of the
     key factors  facing the AOSP's  Expansion 1 project,  and many other large
     construction  projects  around  the  world,  is  the  intense  demand  for
     construction  labour,  materials  and  supplies  which  have  resulted  in
     significant increases in capital costs. This demand is further intensified
     in Alberta by the proposed development of multiple oil sands projects. The
     AOSP is currently  involved in a number of internal  and external  project
     reviews to capture  best  practice in all aspects of the design,  schedule
     and construction strategies. These reviews will continue, including how to
     address  the  twin  challenges  of cost  and  supply.  A final  investment
     decision by the Joint Venture  Owners is anticipated in the fourth quarter
     of 2006. The AOSP Expansion 1 includes pre-building infrastructure such as
     utility plants,  camps,  site pipelines etc. to support multiple  upstream
     expansion projects which the Project believes will create efficiencies and
     economies of scale over the long term. It is also anticipated that capital
     expenditures for Expansion 1 will improve the reliability and availability
     of base operations as the expanded  operations  will create  redundancy in
     critical vessels thereby limiting the downtime  associated with production
     interruptions.

o    Western's  undeveloped land position in the Athabasca region has increased
     significantly to approximately  60,000 acres net to Western in the past 18
     months as a result of numerous  new lease  acquisitions  in which  Western
     owns or will  have the  right to  participate.  Western  has  completed  a
     preliminary  analysis on these  undeveloped  lands including both mineable
     and in-situ.  Based on this analysis,  it is Western's view that there are
     sufficient  bitumen  resources  in place to  support  multiple  expansions
     beyond  the  planned  expansions  at the  AOSP.  Production  from the base
     operation and the first three  expansions is anticipated to exceed 100,000
     barrels per day net to Western.  With the  resource  potential  associated
     with these newly acquired leases, it is Western's view that an incremental
     50,000 to 100,000 barrels per day of production  could be added,  bringing
     Western's share of production into the range of 150,000 to 200,000 barrels
     per day.

The following  discussion of financial  condition and results of operations was
prepared as of July 26, 2006 and should be read in conjunction with the Interim
Unaudited Consolidated Financial Statements for the periods ended June 30, 2006
and 2005 and the Audited Consolidated Financial Statements at December 31, 2005
included in the Annual Report. It offers Management's analysis of our financial
and operating results and contains certain forward-looking  statements relating
but not limited to our operations,  anticipated financial performance, business
prospects  and  strategies.   Forward-looking  information  typically  contains
statements with words such as "anticipate",  "estimate", "expect", "potential",
"could",  or similar words suggesting  future outcomes.  We caution readers and
prospective  investors of the Company's  securities to not place undue reliance
on  forward-looking  information  as by its  nature,  it is  based  on  current
expectations  regarding  future  events that  involve a number of  assumptions,
inherent  risks and  uncertainties,  which could cause actual results to differ
materially from those anticipated by Western.  These risks include, but are not
limited to,  risks of  commodity  prices in the  marketplace  for crude oil and
natural gas; risks  associated with the extraction,  treatment and upgrading of
mineable oil sands deposits;  size and scope of expansions;  risks  surrounding
the level and timing of capital expenditures  required to fulfill the Project's
growth  strategy;  risks of financing these growth  initiatives at commercially
attractive  levels;  risks of being  unable to  participate  in  expansion  and
corresponding  loss  of  voting  rights  in the  AOSP;  risks  relating  to the
execution  of  the  Project's  optimization   strategy;   risks  involving  the
uncertainty  of  estimates  involved  in the reserve  and  resource  estimation
process and ore body  configuration/geometry,  uncertainty in the assessment of
asset  retirement  obligations,  uncertainty in the estimation of future income
taxes,  and  uncertainty  in treatment of capital for royalty  purposes;  risks
surrounding health, safety and environmental  matters; risk of foreign exchange
rate  fluctuations;  risks  and  uncertainties  associated  with  securing  the
necessary  regulatory  approvals for expansion  initiatives;  risks surrounding
major  interruptions  in operational  performance  together with any associated
insurance   proceedings   thereto;   and  risks  associated  with  identifying,
negotiating  and  completing our other business  development  activities,  both
those  that  relate  to oil sands  activities  and  those  that do not,  either
domestically or abroad.  Risks  associated with our  international  initiatives
include,  but are not limited to,  political  and  economic  conditions  in the
countries  in which  we  intend  to  operate,  risks  associated  with  acts of
insurgency  or  terrorism,  changes  in  market  conditions,  political  risks,
including  changes  in law or  government  policy,  the risks  associated  with
negotiating  with  foreign  governments  and risks  generally  associated  with
international activity.

OPERATING RESULTS

PRODUCTION

During the second quarter of 2006, production from the Mine was impacted by the
first  full  Project  turnaround  since  operations   commenced  in  2003.  The
turnaround began in early May and continued over the course of the quarter with
full production  resuming in mid-July.  Full production rates of 36,587 barrels
per day net to Western  were  achieved  during the month of April  whereas  the
impact of the turnaround  reduced  production for the quarter to 15,540 barrels
per day net to Western.  Quarter-over-quarter  production  comparisons  are not
meaningful as a result of the impact of the  turnaround.  This first full plant
turnaround extended beyond the original schedule as additional maintenance work
was required to remove  increased  levels of coke in certain reactor vessels at
the Upgrader.  It is anticipated that major  turnarounds will occur every three
years.

    the three and six months ended June 30, 2006, $0.3 million  (Q2-2005 - nil)
    and $0.5 million (Q2-2005 (6 mos) - nil),  respectively,  has been incurred
    for transportation costs related to Oil Sands.

4    SECOND QUARTER INTERIM REPORT 2006  WESTERN OIL SANDS


Western  recorded  crude oil sales  revenue  of $165.7  million  in the  second
quarter of 2006, including $137.1 million from proprietary  production compared
to $244.2  million in the second  quarter of 2005,  $198.9 million of which was
from  proprietary  production.  This  decrease is the result of the  turnaround
which  occurred  during the second  quarter,  partially  offset by higher sales
price realizations during the quarter.  During the full turnaround,  production
was  interrupted  for 45  days  which  significantly  impacted  second  quarter
operating and financial  results.  Western  received a realized  sales price of
$66.48 per barrel on this  limited  production.  This 36 per cent  increase  in
realized  prices  over the prior  year  period  is the  result of a 33 per cent
increase in West Texas  Intermediate  ("WTI") prices over the comparable period
in 2005,  together with no physical barrels subject to  out-of-the-money  fixed
price swap  contracts  and a narrowing  of the heavy oil  differential  of over
$3.00 per  barrel.  The heavy oil  differential  equated  to 26 per cent of WTI
(US$18.66 per barrel) in the second  quarter of 2006 compared to 41 per cent of
WTI (US$21.90 per barrel) for the prior year period.

     Oil sands  sales  volumes,  including  bitumen and  purchased  feedstocks,
averaged  22,614  barrels  per day in the second  quarter of 2006  compared  to
44,503 barrels per day in the second quarter of 2005. Reduced sales volumes are
a function of the turnaround as there were limited operations during the second
quarter.

     Sales  price   realizations   for  the  second  quarter  of  2006  related
predominantly  to sales activities in April due to little or no activity in May
and June as a result of the turnaround.  Sales price  realizations  were $66.48
per barrel in the second  quarter,  an increase from $48.93 per barrel recorded
in the second  quarter of 2005 and  $55.31  per  barrel  recorded  in the first
quarter  of  2006.  Higher  sales  price  realizations  largely  resulted  from
increases in WTI which averaged US$70.16 for April compared to US$53.17 for the
second quarter of 2005 and US$63.48 for the first quarter of 2006. Contributing
to the improved  realizations was the decrease in the heavy oil differential in
April which  continued  to the end of the quarter.  The heavy oil  differential
narrowed  over  US$8.00  in April  2006  compared  to the  average of the first
quarter of 2006. This narrowing was a function of seasonal asphalt requirements
as refiners build heavy oil  inventories to meet demand and pipeline  reversals
which  opened new markets for Canadian  heavy crude oil.  Included in Western's
sales mix are heavy  crude oil  products  which  attract a lower  sales  price,
thereby affecting our overall sales price realizations. With heavy oil products
in the  overall  sales  mix,  absolute  commodity  prices  and heavy oil market
differentials affect average synthetic crude oil price realizations.  Western's
fixed price swap program ceased at the end of 2005 and this also contributed to
dramatically higher sales price realizations  compared to the second quarter of
2006.

     Western  generated net revenue of $95.6  million in the second  quarter of
2006, after considering the impact of purchased  feedstocks and  transportation
costs  downstream of Edmonton.  By comparison,  Western recorded net revenue of
$148.2  million in the second  quarter of 2005.  This  decrease  stems from the
turnaround conducted throughout most of the second quarter of 2006.  Feedstocks
are crude products  introduced at the Upgrader.  Some feedstocks are introduced
into the  hydrocracking/hydrotreating  process  and  others  are used to create
various blends of synthetic  crude oil products.  The cost of these  feedstocks

OPERATING COSTS

Operating  costs in the second quarter of 2006 were impacted  significantly  by
the full  turnaround.  The  majority  of  operating  costs are fixed in nature,
therefore,  during a  complete  turnaround,  fixed  costs  such as  labour  and
electricity,  are incurred  regardless of production volumes. As the production
base was  significantly  lower in the second  quarter of 2006  compared  to the
prior year period,  unit operating  costs are not comparable  period to period.
Western's  operating costs are also  significantly  influenced by our policy to
expense all turnaround  costs in the period they are incurred.  Western's share
of the  turnaround  expense  for the second  quarter  was $34.9  million and we
anticipate  minor  turnaround  costs in the third quarter  associated  with the
completion of this process.  Total  turnaround costs are higher than previously
estimated due to the additional  work involved with removing  higher amounts of
coke inside certain  reactor vessels at the Upgrader.  Consequently,  operating
costs for the second quarter of 2006 were $62.50 per processed barrel.

     Operating costs of $21.75 per processed  barrel were achieved during April
in  which  normal  operating  conditions  existed.  Despite  the  pressures  on
operating costs  associated with robust  commodity  prices and increased demand
for goods and services, we anticipate a return to operating costs on a per unit
basis experienced in April once normal operations resume.

The above table calculates operating expenses per processed barrel on the basis
of the operating  costs that are  associated  with the  synthetic  crude sales,
excluding  purchased  blend stocks,  for the relevant  period.  The calculation
recognizes that, intrinsic in the Project's operations, bitumen production from
the Mine  receives  an  approximate  three  per cent  uplift as a result of the
hydrotreating/hydroconversion  process,  which is included in  synthetic  crude
sales excluding blendstocks.

ROYALTIES

Royalties  of $0.7  million in the  second  quarter of 2006 were lower than the
comparable  period in 2005 as a result of lower  production  volumes due to the
first full plant turnaround during the second quarter of 2006.  Compared to the
first  quarter  of 2006,  royalties  increased  slightly  as a result of higher
deemed bitumen prices partially offset by reduced production volumes associated
with the turnaround.

CORPORATE RESULTS

RESEARCH AND BUSINESS DEVELOPMENT EXPENSE
Western  incurred  $7.7  million in research  and  development  expenses in the
second  quarter of 2006 compared to $3.4 million in the second quarter of 2005.
Of the $7.7 million  incurred during the second  quarter,  $4.1 million relates
specifically to AOSP-related research and development projects. The increase is
a result of additional efforts in research and business  development as Western
continues  to pursue  opportunities  which may enhance the value of the AOSP in
addition to Western-led initiatives.

GENERAL AND ADMINISTRATIVE EXPENSE
General and  administrative  expenses  ("G&A") were $3.2 million for the second
quarter of 2006 compared to  $2.5million  for the second quarter of 2005 due to
an  increased  number  of  employees  within  Western,   together  with  higher
professional  costs  associated with increased  levels of business  development
activities.

INSURANCE EXPENSE
Insurance expenses were $2.7 million for the second quarter of 2006 compared to
$1.9 million in the second quarter of 2005.  This increase is due to additional
premiums associated with increased levels of coverage,  partially offset by the
strengthening  of the  Canadian  dollar  over  the  comparable  periods  as the
premiums are paid in US dollars but reported for financial  statement  purposes
in Canadian dollars.

INTEREST EXPENSE
Interest  expense  totaled $12.5 million in the second quarter of 2006 compared
to $15.7 million in the second quarter of 2005.  Interest expense in the second
quarter of 2006 is comprised of $10.9  million  related to interest  charges on
debt  obligations  (Q2-2005  - $15.0  million),  $0.7  million  (Q2-2005 - $0.6
million) on capital lease  obligations and $0.9 million  (Q2-2005 - nil) on the
option premium  liability.  The option premium  liability  relates to Western's
strategic crude oil risk management program implemented in the third quarter of
2005, and the decision to defer the premiums  associated  with the put and call
options  purchased  and  sold,  respectively.  Imbedded  in the  prices  of the
deferred options is a financing  charge which is reported as interest  expense.

     The 20 per cent decrease in total interest  expense compared to the second
quarter of 2005 is  largely  the result of the  Canadian  dollar  strengthening
against the US dollar  during this  period  compared to the prior year  period,
thereby  reducing  interest  charges  on our US  denominated  Notes  which  are
reported in Canadian  dollars,  and the significant  reduction in the Revolving
Credit Facility over the comparable period. Interest expense decreased slightly
in the second  quarter of 2006  compared to the first  quarter of 2006 due to a
further  strengthening  of the Canadian  dollar  versus the US dollar,  largely
offset by the larger amounts of debt drawn on the Revolving  Credit Facility to
fund turnaround efforts.

DEPRECIATION, DEPLETION AND AMORTIZATION
Depreciation,  depletion and amortization  ("DD&A") totaled $6.8 million in the
second quarter of 2006 compared to $13.0 million in the second quarter of 2005.
This decrease is the result of lower bitumen production volumes associated with
the full planned plant turnaround since DD&A is based on a unit of production.

FOREIGN EXCHANGE
During the second quarter of 2006,  Western reported a foreign exchange gain of
$25.8 million compared to a loss of $7.0 million in the second quarter of 2005.
As reference  points,  the noon-day  closing foreign  exchange rate on June 30,
2006 was  $0.8969  US/Cdn  compared  to  $0.8568  US/Cdn on March 31,  2006 and
$0.8159  US/Cdn on June 30, 2005.  The average  rate for the second  quarter of
2006 was $0.8912  US/Cdn  compared to $0.8039  US/Cdn for the prior year period
and $0.8659 US/Cdn for the first quarter of 2006.

RISK MANAGEMENT ACTIVITIES

Western's  initial  fixed price hedging  program  expired on December 31, 2005.
Western has no risk  management  financial  instruments  associated with fiscal
2006 and, as such,  crude oil price  realizations in the second quarter of 2006
were not impacted by risk  management  activities.  Realizations  in the second
quarter  of 2005  were  negatively  impacted  by $5.14 per  barrel  due to risk
management activities.

============================================================================================================


     In the third  quarter of 2005,  Western  implemented  strategic  crude oil
hedges in order to provide greater cash flow certainty during those years where
significant AOSP expansion capital expenditures are expected.  Western employed
a collar  strategy  whereby a series of put and call options were purchased and
sold with a number of major financial  institutions.  The program established a
weighted  average  floor  price of  US$52.42  on 20,000  barrels  per day and a
ceiling price of US$92.41 on an average  13,333  barrels per day for the period
January 2007 through to December2009.

     Western is not utilizing  hedge  accounting  treatment under Canadian GAAP
for this  program and, as a result,  certain  mark-to-market  adjustments  will
likely  result in  increased  volatility  in our  reported  net  income.  These
adjustments  are  created  from the  changes  in the fair  market  value of the
financial instruments employed over the time period in question. For the period
ended June 30, 2006,  Western's risk management assets decreased  significantly
in  value  from the  amount  recorded  as at  March  31,  2006  resulting  in a
mark-to-market  loss of $44.5 million  ($33.7 million net of tax) primarily due
to the significant  strengthening  in WTI prices during the quarter.  This loss
does not impact stated cash flow from operations.  In fact, the amount recorded
as a risk  management  asset at the end of the  first  quarter  of 2006 has now
reverted  to a risk  management  liability  given  the  continued  strength  in
underlying  commodity  prices.  While the  mark-to-market  entry for accounting
purposes has been  negative,  the price of WTI has  remained  within the collar
established  under the  strategy.  The current  forward curve of WTI during the
duration of Western's risk management program would also be within this collar.
Consequently, should these forward prices of crude oil materialize, the goal of
Western's risk management program would be achieved - namely,  relatively minor
premiums  incurred to enhance cash flow certainty  during  construction  of the
AOSP  Expansion  1.  Western  continues  to monitor the  portfolio of financial
instruments to determine if modifications are necessary.

INCOME TAXES

For the second quarter of 2006, Western's income tax recovery was $25.5 million
compared to an income tax expense of $18.5  million for the prior year  period.
This recovery is largely due to the net loss  incurred  during the quarter as a
result of the turnaround, together with risk management losses. The recovery is
also a function of reduced federal and provincial income tax rates as announced
by each level of government during the second quarter of 2006.

NET EARNINGS (LOSS)
During the second quarter of 2006, Western reported a net loss of $22.8 million
($0.14 per share) compared to net earnings of $28.7 million ($0.18 per share)
in the second quarter of 2005. The net loss in the second quarter of 2006
includes the impact of $44.5 million ($33.7 million net of tax) in unrealized
risk management losses, in addition to $27.3 million ($24.0 million net of tax)
in unrealized foreign exchange gains on our US dollar denominated debt and
option premium liability. Excluding the impact of risk management and foreign
exchange losses each net of tax, the net loss for the second quarter of 2006
would have equated to $13.1 million compared to net earnings of $41.6 million
for the prior year period.

     An EBITDAX  (Earnings before  Interest,  Taxes,  Depreciation,  Depletion,
Amortization,   Stock-based   Compensation,   Accretion  on  Asset   Retirement
Obligation,  Foreign  Exchange  and Risk  Management)  loss of $8.2 million was
recorded for the second  quarter of 2006  compared to a positive  $84.1 million
for the comparable prior year period. This substantial  decrease is largely due
to the impact of the full plant  turnaround  during the second quarter of 2006,
partially  offset by improved sales price  realizations  on reduced  production
volumes.  Second  quarter 2006 EBITDAX  decreased  $70.3 million over the first
quarter  of 2006  also due to the  full  plant  turnaround  during  the  second
quarter.

     Cash flow from  operations  before  changes in  non-cash  working  capital
("cash flow from  operations") was a net outflow of $20.9 million compared to a
net inflow of $68 million in the second quarter of 2005.  Compared to the prior
period, second quarter results were impacted by the full plant turnaround.

FINANCIAL POSITION

BANK DEBT
During the second  quarter of 2006,  Western  increased its balance drawn under
the Revolving  Credit  Facility to $31million to fund the  turnaround  expenses
incurred during the quarter.  Western  anticipates this balance will be reduced
or repaid  once  production  resumes,  giving  Western  access to the full $340
million  of the  Revolving  Credit  Facility.  The  size of the  facility  is a
function of Western's  share of the before tax present  value  proved  reserves
associated  with  the  Project.  To the  extent  that  Western  is able to book
additional  reserves  associated with the first expansion of the AOSP,  Western
would be  permitted  to increase  its  Revolving  Credit  Facility,  subject to
amending the size of this facility with the existing bank syndicate.

CAPITAL EXPENDITURES
Western's capital  expenditures  totaled $55.8 million in the second quarter of
2006  compared  to $9.3  million  for the  comparable  period in 2005.  Capital
expenditures  in the second  quarter of 2006  included  $13.3  million for base
operations,  $7.1 million for sustaining  capital,  $30.0 million for expansion
related capital,  $4.0 million for new business  development and $1.4 for other
corporate purposes.

was the result of a $22.0  million  decrease  in  accounts  receivable,  a $6.2
million decrease in inventory,  a $6.0 million increase in accounts payable and
a $2.1 million decrease in prepaid  expenses.  The increase in accounts payable
is a function of costs associated with the turnaround during the second quarter
offset by lower accrued interest on Western's long-term notes at June 30, 2006,
as only two months of accrued  interest  are  included  compared to five months
accrued at March 31, 2006. The decrease in accounts receivable is the result of
lower sales volumes associated with the full plant turnaround during the second
quarter. Inventory is lower as a result of a greater proportion of lower priced
volumes than high priced  volumes  compared to the end of the first  quarter of
2006.

INSURANCE CLAIMS
There were no new  developments  during the second quarter of 2006 with respect
to Western's ongoing  arbitration  proceedings  concerning the Cost Overrun and
Project Delay insurance policy,  known as Section IV. Western  anticipates that
formal arbitration hearings will commence in 2007.

FLOW-THROUGH SHARES
There were no new  developments  during the second quarter of 2006 with respect
to Western's issuance of flow-through  shares in 2001 and 2002 and the possible
re-characterization  of  qualifying  expenditures  by  Canada  Revenue  Agency.
Western will provide further updates once information is made available.

KURDISTAN UPDATE

As announced on May 30, 2006, Western's wholly-owned subsidiary,  WesternZagros
Limited,  entered into an Exploration and Production  Sharing  Agreement (EPSA)
with the Kurdistan  Regional  Government in northern Iraq. This opportunity may
potentially give Western access to an additional  world-class asset with large,
long-life,  reserves with a significantly lower cost structure than our current
oil sands asset. Our initial exploration capital commitment of US$45 million is
to be expended prior to the expiry of four years from the effective date of the
contract.  Further  expenditures  will  depend on  exploration  success and the
timing of executing a development  program. Our exploration area covered by the
EPSA spans approximately 3,700 square kilometres or 914,000 acres.

     Western's  team  of   professionals,   dedicated   specifically   to  this
initiative,  has taken  preliminary  steps to fulfill the obligations under the
EPSA.  Measured  progress  has  been  made to date  on many  levels,  including
seismic,  engineering  and logistics.  Western  anticipates  that progress will
continue as planned,  culminating  in an initial  three well drill program over
three  different  potential  structures  within our contract area.  Western has
chosen  to  account  for  its  operations  in  Kurdistan  using  the  full-cost
accounting methodology.

     On the personnel front,  Western is pleased to announce the appointment of
Mr. Jack  Blackshear to the key position of Resident  Manager,  Kurdistan.  Mr.
Blackshear brings with him significant  international  drilling and operational
experience  through his  distinguished  career with some of the world's premier
integrated energy companies.

OUTLOOK

The AOSP  anticipates  production  levels  returning  to the  historical  norms
achieved  prior to the full  plant  turnaround  and  maintaining  these  levels
through the remainder of the year. Despite the extended turnaround schedule, by
many  measures  the process was a success and the  education  gathered  will be
invaluable as future  turnarounds  are conducted.  During the  turnaround,  the
Project  implemented certain production  optimization  initiatives which should
enhance the reliability and  availability of the Project.  As announced on June
12, 2006,  Western revised its production  guidance to 26,000 to 27,000 barrels
per day for 2006 and we continue to hold this estimate.

     The  Joint  Venture  Owners  are  proceeding   steadily  towards  a  final
investment decision on the first 100,000 barrel per day AOSP expansion which is
expected  to occur  in the  fourth  quarter  of 2006.  Deliberate  and  careful
analyses of the costs  associated  with this  expansion  in the midst of heated
construction  market are a primary  focus with cost

10        SECOND QUARTER INTERIM REPORT 2006  WESTERN OIL SANDS


and schedule control a top priority.  As announced on July 5, 2006,  subsequent
to the end of the quarter,  capital costs  associated  with the first expansion
are under  significant  pressure.  Preliminary  revised  estimates  indicate  a
potential  increase  in  capital  costs  of a  fully  integrated  expansion  of
approximately  50 per cent higher than those  anticipated  last year.  The AOSP
Expansion 1 includes pre-building infrastructure such as utility plants, camps,
site pipelines etc. to support  multiple  expansion  projects which the Project
believes  will create  efficiencies  and economies of scale over the long term.
Several construction gating procedures must still be completed prior to a final
determination  of capital costs.  Western will have 90 days from the receipt of
the expansion notice to make the final investment decision.

     Western  expects to continue  participating  in future mine expansions and
development  together  with the other  Joint  Venture  Owners.  Beyond the AOSP
Expansion 1, Western is also independently  evaluating  alternative  downstream
solutions   with  the  goal  of  improving   product  yields  and  sales  price
realizations.  To meet these stated goals,  Western is committed to a long-term
strategy which involves commercially attractive integrated downstream solutions
for upgrading bitumen into light synthetic crude oil products for future mining
and in-situ production volumes.

     Western's  undeveloped land position in the Athabasca region has increased
significantly  in the past 18  months  to  approximately  60,000  acres  net to
Western as a result of numerous new lease acquisitions in which Western owns or
will  have the  right to  participate.  Western  has  completed  a  preliminary
analysis on these undeveloped lands including both mineable and in-situ.  Based
on this  analysis,  it is  Western's  view that  there are  sufficient  bitumen
resources in place to support multiple expansions beyond the planned expansions
at the AOSP.  Production from the base operation and the first three expansions
is  anticipated  to exceed  100,000  barrels per day net to  Western.  With the
resource potential  associated with these newly acquired mineable leases, it is
Western's  view  that an  incremental  50,000  to  100,000  barrels  per day of
production  could be added,  bringing  Western's  share of production  into the
range of 150,000 to 200,000 barrels per day.

     Western is also currently reviewing the resource potential attributable to
leases  outside of the current  operation and the AOSP  Expansion 1. As part of
Western's  annual filing process,  it is anticipated  that we will disclose the
contingent  or  potentially  recoverable  resources,  both on a volumetric  and
economic  basis,  on these leases - namely,  Lease 13 (remainder  after current
Mine and Expansion 1), 88, 89, 90, 9 and 17. Western is also taking early steps
to quantify the resource potential  attributable to leases recently acquired by
our Joint Venture  Participants,  in addition to Lease353 which was acquired by
Western. The resource potential will be disclosed when the analysis is provided
by the experts engaged in these assessments.

BUSINESS AND FINANCIAL RISKS
Western is subject to a number of business and financial risks that are typical
given  the  nature of  Western's  operations.  These  risks  are  described  in
Western's previous public disclosures, including the 2005 Annual Report and the
Annual Information Form, which are available on the Company's website.

NON-GAAPFINANCIAL MEASURES
Western includes cash flow from operations per share, cash flow from operations
excluding hedging activities,  earnings before interest,  taxes,  depreciation,
depletion  and  amortization,  stock-based  compensation,  accretion  on  asset
retirement  obligation,  foreign  exchange  gains and gains and  losses on risk
management activities ("EBITDAX"), EBITDAX excluding hedging activities and net
earnings  excluding hedging activities as investors may use this information to
better analyze our operating  performance.  We also include  certain per barrel
information,  such as  realized  crude oil sales  price,  to  provide  per unit
numbers that can be compared against industry benchmarks,  such as the Edmonton
PAR benchmark. The additional information should not be considered in isolation
or as a substitute for measures of operating performance prepared in accordance
with Canadian  Generally  Accepted  Accounting  Principles  ("GAAP").  Non-GAAP
financial measures do not have any standardized  meaning prescribed by Canadian
GAAP and are therefore  unlikely to be comparable to similar measures presented
by other issuers.  Management believes that, in addition to Net Earnings (Loss)
per Share and Net Earnings  (Loss)  Attributable to Common  Shareholders  (both
Canadian  GAAP  measures),  cash flow  from  operations  per share and  EBITDAX
provide a better basis for evaluating our operating  performance,  as they both
exclude  fluctuations  on the US dollar  denominated  Senior  Secured Notes and
certain other non-cash items, such as depreciation, depletion and amortization,
and future  income  tax  recoveries.  In  addition,  EBITDAX  provides a useful
indicator  of our ability to fund our  financing  costs and any future  capital
requirements.

                                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited) (Tabular amounts in $ thousands, except for share amounts)

The interim  consolidated  financial statements include the accounts of Western
Oil Sands Inc. and its subsidiaries (the  "Corporation"),  and are presented in
accordance with Canadian Generally Accepted Accounting Principles.  The interim
consolidated  financial statements have been prepared using the same accounting
policies and methods of computation as the  consolidated  financial  statements
for the year ended  December  31,  2005.  The  disclosures  provided  below are
incremental to those included in the annual consolidated  financial statements.
The interim  consolidated  financial  statements  should be read in conjunction
with  the  consolidated  financial  statements  and the  notes  thereto  in the
Corporation's annual report for the year ended December 31, 2005.


1. ACCOUNTING POLICY

Property,  plant  and  equipment  ("PP&E")  assets  are  recorded  at cost less
accumulated provisions for depreciation,  depletion and amortization.  Prior to
the commencement of commercial operations,  interest costs of debt attributable
to major development projects are capitalized.

OIL SANDS MINING
Capitalized  costs  include  costs  specifically  related  to the  acquisition,
exploration,  development  and  construction of the Athabasca Oil Sands Project
("AOSP") and other projects,  including asset retirement obligations. Oil Sands
Mining  assets are  reviewed  for  impairment  annually or  whenever  events or
conditions  indicate that their net carrying amount may not be recoverable from
estimated  future cash flows.  If an impairment is  determined,  the assets are
written down to the fair value.

     Depletion  on oil sands  mining  properties  is provided  over the life of
proved and probable reserves on a unit of production basis, commencing when the
facilities  are  substantially  complete and after  commercial  production  has
begun.

CONVENTIONAL CRUDE OIL AND IN-SITU OIL SANDS
The Corporation  accounts for its conventional crude oil and in-situ properties
and  equipment  in  accordance   with  the  Canadian   Institute  of  Chartered
Accountants'  guideline on full cost  accounting  in the oil and gas  industry.
Under this method,  all costs  associated with the acquisition of,  exploration
for and the  development  of  conventional  crude  oil  and  in-situ  reserves,
including asset retirement  obligations are capitalized and accumulated  within
cost  centres  on  a   country-by-country   basis.   Such  costs  include  land
acquisition,  geological  and  geophysical  activity,  drilling  and testing of
productive  and  non-productive  wells,  carrying  costs  directly  related  to
unproved  properties,  major  development  projects  and  administrative  costs
directly related to exploration and development activities.

     Once  the  Corporation  commences  commercial  production  from  the  cost
centres,  capitalized costs accumulated within each cost centre are depleted on
the  unit-of-production  method based on the estimated  proved reserves of that
country using estimated future prices and costs.  Proceeds from the disposal of
properties are normally deducted from the full cost pool without recognition of
a gain or loss unless that deduction  would result in a change to the depletion
rate by 20 percent or more, in which case, a gain or loss is recorded.

     In determining  the depletion  base, the  Corporation  includes  estimated
future costs to be incurred in developing proved reserves and excludes the cost
of  unproved  properties  and  major  development  projects.   Costs  of  major
development projects and costs of acquiring and evaluating significant unproved
properties  are  excluded,  on a cost  centre  basis,  from  costs  subject  to
depletion   until  it  is  determined   whether  or  not  proved  reserves  are
attributable  to the  properties,  or  impairment  has  occurred.  To date,  no
depletion  related  to the  Corporation's  conventional  crude oil and  in-situ
properties has been recorded as commercial operations have not commenced.

     The Corporation  reviews the carrying amount of its conventional crude oil
and in-situ  properties  relative  to their  recoverable  amount (the  "ceiling
test")  for each  cost  centre  at each  annual  balance  sheet  date,  or more
frequently if  circumstances  or events indicate  impairment has occurred.  The
recoverable amount is calculated as the sum of:

     o   the undiscounted future cash flow from proved reserves using expected
         future prices and costs;

     o   the cost of unproved properties; and

     o   the costs of major development projects less impairment.


                    SECOND QUARTER INTERIM REPORT 2006  WESTERN OIL SANDS    15


     If the carrying amount of the properties exceeds their recoverable amount,
an impairment loss is recognized in depletion equal to the amount by which the
carrying amount of the properties exceeds their fair value. Fair value is
calculated as the sum of:

     o   the future cash flows from proved and probable reserves using expected
         future prices and costs, discounted at a risk-free interest rate; and

     o   the cost, less impairment,  of unproved reserves and major development
         projects that do not have probable reserves attributable to them.

CORPORATE AND OTHER
Corporate and Other PP&E assets are depreciated on a  straight-line  basis over
their useful lives.

* Accumulated Depreciation, Depletion and Amortization

At June 30, 2006,  the Producing  Assets in the AOSP include  asset  retirement
costs,  net of  amortization  of $7.1 million ($7.2 million - 2005).  Costs not
currently  subject to depreciation,  depletion and  amortization  include $87.4
million  relating to the AOSP and $5.7 million relating to Corporate and Other,
as the projects associated with these costs were not substantially complete and
there has been no commercial  production  associated with these  projects.  All
costs included in the Kurdistan Exploration Project are excluded from depletion
as they  represent  costs  related to  unproved  properties  incurred in a cost
centre that are considered to be in the pre-production stage. Currently,  there
are no proved  reserves in this cost centre.  All costs,  net of any associated
revenues, in this cost centre have been capitalized.

The capital  lease  obligation  relates to the  Corporation's  share of capital
costs for the  hydrogen-manufacturing  unit within the AOSP.  Repayments of the
principal  obligation  are $1.3 million per year and are scheduled to remain at
that level until repaid.

     Under the  Operating  Lease  for  Mobile  Equipment,  the  Corporation  is
committed to pay its 20 per cent share of an amount equal to 85 per cent of the
original  cost of the  equipment  to the  lessor at the end of the terms of the
lease.  Accordingly,  the Corporation recognized,  as a liability, a portion of
this future payment as it relates to the service life of the equipment that has
passed.  During  the  three and six  month  period  ended  June 30,  2006,  the
Corporation  paid $0.4 million and $0.6 million,  in regard to this  obligation
(June 30, 2005 - $0.1 million and $1.5 million, respectively).


5. OPTION PREMIUM LIABILITY

The Corporation  deferred  payment and receipt of the premiums  associated with
the  options  described  in Note  13(b)  until  the  settlement  of the  option
contracts  between  2007 and  2009.  The  total  net  premiums  payable  by the
Corporation are US$21.9 million for 2007,  US$32.4 million for 2008 and US$27.8
million for 2009. On the dates that the option  contracts  were entered,  a net
liability  was  recognized on the  consolidated  balance sheet at the estimated
present value of the net premiums payable. Subsequent to the inception dates of
the option  contracts,  interest  expense is recognized,  with a  corresponding
increase to the liability,  at annual rates ranging from 4.25% to 4.50%. During
the three and six month  periods  ended June 30,  2006,  $0.9  million and $1.9
million of interest  expense was  recognized  (June 30, 2005 - nil). The option
premium  liability is denominated in US dollars and is translated into Canadian
dollars at the period end exchange rate. The unrealized  foreign  exchange gain
arising on the option  premium  liability  for the three and six month  periods
ended June 30, 2006 was $3.9 million and $3.8 million,  respectively  (June 30,
2005 - nil).

The basic and diluted  weighted  average  number of common shares  outstanding,
both  current  and prior  period,  reflect a  three-for-one  stock split of the
Corporation's  common shares on May 30, 2005. The basic weighted average number
of common  shares for the three and six month  periods  ended June 30, 2006 are

160,039,942).  Due to a loss for the three and six month periods ended June 30,
2006, no  incremental  shares were included for the diluted  earnings per share
weighted average number because the effect would be anti-dilutive.  The diluted
weighted  average  number of shares for the three and six month  periods  ended
June 30, 2005 were 162,180,067 and 162,169,374, respectively.

12. COMMITMENTS AND CONTINGENCIES

EXPLORATION AND PRODUCTION SHARING AGREEMENT
The Corporation,  through its wholly-owned  subsidiary,  WesternZagros Limited,
entered into an Exploration and Production Sharing Agreement ("EPSA") dated May
4, 2006 with the Kurdistan Regional Government,  Sulaymaniyah Administration to
explore  for  conventional  oil and gas in the  Federal  Region  of  Kurdistan.
Management  expects  this  agreement  to be  passed  into  law by  the  unified
government of the Federal  Region of Kurdistan  within the next few months,  at
which  time,  the  agreement  will be  effective.  Under the terms of the EPSA,
WesternZagros has made a minimum contractual commitment of US$45 million for an
exploration program for a period of four years from the date the EPSA is passed
into law.

13. FINANCIAL INSTRUMENTS AND RISK MANAGEMENT

The Corporation has entered into various commodity-pricing  agreements designed
to mitigate the exposure to the  volatility  of crude oil prices in US dollars,
thereby  providing  greater  certainty of future cash flow from the sale of the
Corporation's  synthetic crude oil products.  This risk management  strategy is
intended to protect the  Corporation's  base and future  capital  programs  and
ensure the  funding  of debt  obligations.  Certain of these  commodity-pricing
agreements were accounted for as hedges, as they qualified for hedge accounting
under  Accounting  Guideline  13 and were  designated  as hedges,  while  other
commodity-pricing  agreements are accounted for under fair value  accounting as
they did not  qualify  or have not been  designated  as hedges  for  accounting
purposes.

(a) HEDGE ACCOUNTING
There  were no crude  swap  positions  in place  during the three and six month
periods ended June 30, 2006 as the crude oil swaps were  completed in 2005. For
the three and six month periods ended June 30, 2005, the Corporation's revenues
were reduced by $20.8 million and $57.6 million,  respectively,  from crude oil
price hedging losses.

                  SECOND QUARTER INTERIM REPORT 2006  WESTERN OIL SANDS      21


(b) FAIR VALUE ACCOUNTING

The  Corporation  has put options at strike  prices  ranging  from  US$50.00 to
US$55.00  per barrel,  averaging  US$52.42 per barrel for the three year period
beginning  January 1, 2007.  The  premiums for the  purchased  put options were
partially offset through the sale of call options at strike prices ranging from
US$90.00 to US$95.00  per barrel,  averaging  US$92.41 per barrel for the three
year period beginning  January 1, 2007,  resulting in a net premium  liability.
Payment of the net premium  liability is deferred  until the  settlement of the
option  contracts  between 2007 and 2009. As at June 30, 2006, the  Corporation
had outstanding the following put and call options:



                                                                            2007         2008         2009
- -----------------------------------------------------------------------------------------------------------

===========================================================================================================


     The fair value of the option  contracts was recognized on the consolidated
balance  sheet on the dates they were  entered  into.  During the three and six
month periods  ended June 30, 2006,  the  Corporation  recognized an unrealized
loss of $44.5  million  and $112.2  million  (June 30,  2005 - nil) on the Risk
Management  Asset  (Liability),  marking it to the fair value at the end of the
period.  The counterparties to these put and call options have investment grade
credit ratings,  thereby  partially  mitigating the credit risk associated with
these financial instruments.

     The following  table presents the  reconciliation  of the Risk  Management
Asset (Liability):
