 i.
    
    We have prepared an independent evaluation of the reserves of Ivanhoe Energy Inc. (the
Company) for the management and the board of directors of the Company. The primary
purpose of our evaluation report was to provide estimates of reserves information in
support of the Companys year-end reserves reporting requirements under US Securities
Regulation S-K and for other internal business and financial needs of the Company.
 ii.
    
    We have evaluated the reserves of the Company as at December 31, 2009. The completion
date of our report is January 20, 2010.
 iii.
    
    The following table sets forth the geographic area covered by our report, proved
reserves estimated using constant prices and costs, and the proportion of the total company
that we have evaluated.

    As noted in item iii., our evaluation covered all of the Companys proved reserves. We
carried out our evaluation in accordance with standards set out in the Canadian Oil and Gas
Evaluation Handbook (the COGE Handbook) with the necessary modifications to reflect
definitions and standards under the U.S. Financial Accounting Standards Board policies (the
FASB Standards) and the legal requirements under the U.S. Securities and Exchange
Commission (SEC requirements).

v.
    
    As required under SEC Regulation S-K, reserves are those quantities of oil and gas that
are estimated to be economically producible under existing economic conditions. As
specified, in determining economic production, constant product reference prices have been
based on a 12-month average price, calculated as the unweighted arithmetic average of the
first-day-of-the-month price for each month within the 12-month period prior to the
effective date of our report. In our economic analysis, operating and capital costs are
those costs estimated as applicable at the effective date of our report, with no future
escalation. Where deemed appropriate, the capital costs and revised operating costs
associated with the implementation of committed projects designed to modify specific field
operations in the future may be included in economic projections.
 vi.
    
    Our report has been prepared assuming the continuation existing regulatory and fiscal
conditions subject to the guidance in the COGE Handbook and SEC regulations.
Notwithstanding that the Company currently has regulatory approval to produce the reserves
identified in our report, there is no assurance that changes in regulation will not occur;
such changes, which cannot reliably be predicted, could impact the Companys ability to
recovery the estimated reserves.

vii.
    
    Oil and gas reserves estimates have an inherent degree of associated uncertainty the
degree of which is affected by many factors. Reserves estimates will vary due to the
limited and imprecise nature of data upon which the estimates of reserves are predicated.
Moreover, the methods and data used in estimating reserves are often necessarily indirect
or analogical in character rather than direct or deductive. Furthermore, the persons
involved in the preparation of reserves estimates and associated information are required,
in applying geosciences, petroleum engineering and evaluation principles, to make numerous
unbiased judgments based upon their educational background, professional training, and
professional experience. The extent and significance of the judgments to be made are, in
themselves, sufficient to render reserves estimates inherently imprecise. Reserves
estimates may change substantially as additional data becomes available and as economic
conditions impacting oil and gas prices and costs change. Reserves estimates will also
change over time due to other factors such as knowledge and technology, fiscal and economic
conditions, contractual, statutory and regulatory provisions.
 viii.
    
    In our opinion, the reserves information evaluated by us have, in all material
respects, been determined in accordance with all appropriate industry standards, methods
and procedures applicable for the filing of reserves information under U.S. SEC Regulation
S-K.
 ix.
    
    A summary of the Company reserves evaluated by us is provided in item iii.
