Reserves Notes:


1.  Company Gross reserves are working interest share before deduction of
    royalties and excluding any royalty interests.
2.  Company Net reserves are working interest share after deduction of
    royalties and including any royalty interests.
3.  BOE values may not calculate due to rounding.
4.  Forecast pricing assumptions utilized by the Independent Qualified
    Reserves Evaluators in the reserve estimates were provided by Sproule

A foreign exchange rate of 0.7800 US$/C$ for 2017, 0.8200 US$/C$ for 2018,

5.  A barrel of oil equivalent ("BOE") is derived by converting six thousand
    cubic feet of natural gas to one barrel of crude oil (6 Mcf:1 bbl). This
    conversion may be misleading, particularly if used in isolation, since
    the 6 Mcf: 1 bbl ratio is based on an energy equivalency conversion
    method primarily applicable at the burner tip and does not represent a
    value equivalency at the wellhead. In comparing the value ratio using
    current crude oil prices relative to natural gas prices, the 6 Mcf: 1
    bbl conversion ratio may be misleading as an indication of value.
6.  Metrics included herein are commonly used in the oil and natural gas
    industry and are determined by Canadian Natural as set out in the notes
    below. These metrics do not have standardized meanings and may not be
    comparable to similar measures presented by other companies and may be
    misleading when making comparisons. Management uses these metrics to
    evaluate Canadian Natural's performance over time. However, such
    measures are not reliable indicators of Canadian Natural's future
    performance and future performance may vary.
7.  Reserve additions and revisions are comprised of all categories of
    Company Gross reserve changes, exclusive of production.
8.  Production replacement or Reserve replacement ratio is the Company Gross
    reserve additions and revisions, for the relevant reserve category,
    divided by the Company Gross production in the same period.
9.  Reserve Life Index is based on the amount for the relevant reserve
    category divided by the 2017 proved developed producing production
    forecast prepared by the Independent Qualified Reserve Evaluators.
10. Finding, Development and Acquisition ("FD&A") costs are calculated by
    dividing the sum of total exploration, development and acquisition
    capital costs incurred in 2016 by the sum of total additions and
    revisions for the relevant reserve category.
11. FD&A costs including change in Future Development Capital ("FDC") are
    calculated by dividing the sum of total exploration, development and
    acquisition capital costs incurred in 2016 and net change in FDC from
    December 31, 2015 to December 31, 2016 by the sum of total additions and
    revisions for the relevant reserve category. FDC excludes all
    abandonment and reclamation costs.
12. Recycle Ratio is the operating netback (in $/BOE for the year) divided
    by the FD&A (in $/BOE). Operating netback is production revenues,
    excluding realized gains and losses on commodity hedging, less
    royalties, transportation and production expenses, calculated on a per
    BOE basis.

Forward-Looking Statements

Certain statements relating to Canadian Natural Resources Limited (the "Company") in this document or documents incorporated herein by reference constitute forward-looking statements or information (collectively referred to herein as "forward-looking statements") within the meaning of applicable securities legislation. Forward-looking statements can be identified by the words "believe", "anticipate", "expect", "plan", "estimate", "target", "continue", "could", "intend", "may", "potential", "predict", "should", "will", "objective", "project", "forecast", "goal", "guidance", "outlook", "effort", "seeks", "schedule", "proposed" or expressions of a similar nature suggesting future outcome or statements regarding an outlook. Disclosure related to expected future commodity pricing, forecast or anticipated production volumes, royalties, operating costs, capital expenditures, income tax expenses and other guidance, constitute forward-looking statements. Disclosure of plans relating to and expected results of existing and future developments, including but not limited to the Horizon Oil Sands operations and future expansions, Primrose thermal projects, Pelican Lake water and polymer flood project, the Kirby Thermal Oil Sands Project, the construction and future operations of the North West Redwater bitumen upgrader and refinery, and construction by third parties of new or expansion of existing pipeline capacity or other means of transportation of bitumen, crude oil, natural gas or synthetic crude oil ("SCO") that the Company may be reliant upon to transport its products to market also constitute forward-looking statements. This forward-looking information is based on annual budgets and multi-year forecasts, and is reviewed and revised throughout the year as necessary in the context of targeted financial ratios, project returns, product pricing expectations and balance in project risk and time horizons. These statements are not guarantees of future performance and are subject to certain risks. The reader should not place undue reliance on these forward-looking statements as there can be no assurances that the plans, initiatives or expectations upon which they are based will occur.

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 can be profitably produced in the future. There are numerous uncertainties inherent in estimating quantities of proved and proved plus probable crude oil, natural gas and natural gas liquids ("NGLs") reserves and in projecting future rates of production and the timing of development expenditures. The total amount or timing of actual future production may vary significantly from reserve and production estimates.

The forward-looking statements are based on current expectations, estimates and projections about the Company and the industry in which the Company operates, which speak only as of the date such statements were made or as of the date of the report or document in which they are contained, and are subject to known and unknown risks and uncertainties that could cause the actual results, performance or achievements of the Company to be materially different from any future results, performance or achievements expressed or implied by such forward-looking statements. Such risks and uncertainties include, among others: general economic and business conditions which will, among other things, impact demand for and market prices of the Company's products; volatility of and assumptions regarding crude oil and natural gas prices; fluctuations in currency and interest rates; assumptions on which the Company's current guidance is based; economic conditions in the countries and regions in which the Company conducts business; political uncertainty, including actions of or against terrorists, insurgent groups or other conflict including conflict between states; industry capacity; ability of the Company to implement its business strategy, including exploration and development activities; impact of competition; the Company's defense of lawsuits; availability and cost of seismic, drilling and other equipment; ability of the Company and its subsidiaries to complete capital programs; the Company's and its subsidiaries' ability to secure adequate transportation for its products; unexpected disruptions or delays in the resumption of the mining, extracting or upgrading of the Company's bitumen products; potential delays or changes in plans with respect to exploration or development projects or capital expenditures; ability of the Company to attract the necessary labour required to build its thermal and oil sands mining projects; operating hazards and other difficulties inherent in the exploration for and production and sale of crude oil and natural gas and in mining, extracting or upgrading the Company's bitumen products; availability and cost of financing; the Company's and its subsidiaries' success of exploration and development activities and its ability to replace and expand crude oil and natural gas reserves; timing and success of integrating the business and operations of acquired companies; production levels; imprecision of reserve estimates and estimates of recoverable quantities of crude oil, natural gas and NGLs not currently classified as proved; actions by governmental authorities; government regulations and the expenditures required to comply with them (especially safety and environmental laws and regulations and the impact of climate change initiatives on capital and operating costs); asset retirement obligations; the adequacy of the Company's provision for taxes; and other circumstances affecting revenues and expenses.

The Company's operations have been, and in the future may be, affected by political developments and by federal, provincial and local laws and regulations such as restrictions on production, changes in taxes, royalties and other amounts payable to governments or governmental agencies, price or gathering rate controls and environmental protection regulations. Should one or more of these risks or uncertainties materialize, or should any of the Company's assumptions prove incorrect, actual results may vary in material respects from those projected in the forward-looking statements. The impact of any one factor on a particular forward-looking statement is not determinable with certainty as such factors are dependent upon other factors, and the Company's course of action would depend upon its assessment of the future considering all information then available.

Readers are cautioned that the foregoing list of factors is not exhaustive. Unpredictable or unknown factors not discussed in this report could also have material adverse effects on forward-looking statements. Although the Company believes that the expectations conveyed by the forward-looking statements are reasonable based on information available to it on the date such forward-looking statements are made, no assurances can be given as to future results, levels of activity and achievements. All subsequent forward-looking statements, whether written or oral, attributable to the Company or persons acting on its behalf are expressly qualified in their entirety by these cautionary statements. Except as required by law, the Company assumes no obligation to update forward-looking statements, whether as a result of new information, future events or other factors, or the foregoing factors affecting this information, should circumstances or Management's estimates or opinions change.
