Exhibit 99.1

Disclosure about Oil and Gas Producing Activities - Accounting Standards Codification 932, “Extractive Activities - Oil and Gas” (unaudited)

The following disclosures have been prepared in accordance with FASB Accounting Standards Codification 932, “Extractive Activities - Oil and Gas”.

The unaudited supplemental information on oil and gas exploration and production activities for 2017 and 2016 has been presented in accordance with the revised reserve estimation and disclosure rules, which were not applied retrospectively.

Oil and Gas Reserves

Proved oil and gas reserves are those quantities of oil and gas which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations.

Proved developed oil and gas reserves are proved reserves that can be expected to be recovered: (i) through existing wells with existing equipment and operating methods or in which the cost of the required equipment is relatively minor compared to the cost of a new well; and (ii) through installed extraction equipment and infrastructure operational at the time of the reserves estimate if the extraction is by means not involving a well.

Proved undeveloped oil and gas reserves are proved reserves that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion.

Canadian provincial royalties are determined based on a graduated percentage scale, which varies with prices and production volumes. Canadian reserves, as presented on a net basis, assume prices and royalty rates in existence at the time the estimates were made, and Husky’s estimate of future production volumes. Future fluctuations in prices, production rates, or changes in political or regulatory environments could cause Husky’s share of future production from Canadian reserves to be materially different from that presented.

Subsequent to December 31, 2017, no major discovery or other favourable or adverse event is believed to have caused a material change in the estimates of developed or undeveloped reserves as of that date.

Note that the numbers in each column of the tables throughout this exhibit may not add due to rounding.

⁽¹⁾  Net reserves are the Company’s lessor royalty, overriding royalty and working interest share of the gross remaining reserves, after deduction of any crown, freehold and overriding royalties. Such royalties are subject to change by legislation or regulation and can also vary depending on production rates, selling prices and timing of initial production.

⁽²⁾  Reserves are the estimated remaining quantities of oil and gas and related substances anticipated to be economically producible, as of a given date, by application of development projects to known accumulations.

⁽³⁾  Proved oil and gas reserves are those quantities of oil and gas which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a given date forward, from known reservoirs, and under existing economic conditions, operating methods and government regulations.

⁽⁴⁾  Proved developed oil and gas reserves are proved reserves that can be expected to be recovered: (i) through existing wells with existing equipment and operating methods or in which the cost of the required equipment is relatively minor compared to the cost of a new well; and (ii) through installed extraction equipment and infrastructure operational at the time of the reserves estimate if the extraction is by means not involving a well. Proved undeveloped oil and gas reserves are proved reserves that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion.

⁽⁵⁾  Husky’s beneficial interest in Indonesia and the Madura Strait Block is held by way of a 40 percent interest in Husky—CNOOC Madura Limited (“HCML”), an entity that is party to a PSC with the Government of Indonesia. Husky has entered into a unanimous shareholder agreement dated April 8, 2008 with the other shareholders of HCML that provides for joint control of HCML. International Financial Reporting Standard 11, “Joint Arrangements” (“IFRS 11”), requires Husky to follow the equity method of accounting for its investment in the Madura Strait Block. IFRS 11 focuses on the legal form of the corporate structure in which Husky’s Madura assets are held. Husky holds its interest in the Madura Strait Block through HCML and accordingly is required to use the equity method to account for this interest. As a consequence, Husky has disclosed Indonesia as a separate entity in the above disclosure because the Madura Strait Block is accounted for by the equity method of accounting.

⁽⁶⁾  In addition to the major changes to proved reserves in 2017 described under “Oil and Gas Reserves Disclosures—Reconciliation of Gross Proved Reserves” in Document A—Annual Information Form, bitumen reserves in Sunrise were economic under SEC price forecasts as of December 31, 2017 (they were uneconomic in 2015 and 2016) and account for the vast majority of the revisions in 2017.

The Company’s reserve replacement ratio⁽¹⁾ for the last three years was as follows:

Net Proved Oil and Gas Reserves	2017			2016			2015
Excluding Acquisition & Divestiture		611	%		80	%		(184	)%
Including Acquisition & Divestiture		558	%		29	%		(188	)%

⁽¹⁾  Reserves replacement ratio is calculated as net reserve additions during the period divided by total production during the period. Net reserves additions include: revisions, purchases, sales, improved recovery, and discoveries and extensions. The negative reserves replacement ratio for 2015 is a result of the Sunrise bitumen reserves becoming uneconomic. SImilarly, the large positive reserves replacement ratio for 2017 is a reflection of the Sunrise bitumen reserves becoming economic again in 2017.

Standardized Measure of Discounted Future Net Cash Flows Relating to Proved Oil and Gas Reserves (unaudited)

The following information has been developed utilizing procedures prescribed by FASB Accounting Standards Codification 932, “Extractive Activities - Oil and Gas” and is based on crude oil and natural gas reserve and production volumes estimated by the Company’s reserves evaluation staff. It may be useful for certain comparison purposes, but should not be solely relied upon in evaluating Husky or its performance. Further, information contained in the following table should not be considered as representative of realistic assessments of future cash flows, nor should the standardized measure of discounted future net cash flows be viewed as representative of the current value of Husky’s reserves.

The future cash flows presented below are based on average sales prices and cost rates, and statutory income tax rates in existence as of the date of the projections. It is expected that material revisions to some estimates of crude oil and natural gas reserves may occur in the future, development and production of the reserves may occur in periods other than those assumed, and actual prices realized and costs incurred may vary significantly from those used.

Management does not rely upon the following information in making investment and operating decisions. Such decisions are based upon a wide range of factors, including estimates of probable as well as proved reserves, and varying price and cost assumptions considered more representative of a range of possible economic conditions that may be anticipated.

The computation of the standardized measure of discounted future net cash flows relating to proved oil and gas reserves at December 31, 2017 was based on the New York Mercantile Exchange 2017 average natural gas cash market price of U.S. $2.98/mmbtu (2016 average - U.S. $2.48 mmbtu; 2015 average - U.S. $2.59/mmbtu) and on crude oil prices computed with reference to the 2017 average WTI spot price of U.S. $51.19/ bbl (2016 average - U.S. $42.68/bbl; 2015 average - U.S. $50.20/bbl). Natural gas prices for China and Indonesia reserves are based on various Gas Sales Agreements, are included in the AIF, and were updated as result of price negotiations with various purchasers.

⁽¹⁾ The schedules above are calculated using year average prices and year-end costs, statutory income tax rates and existing proved oil and gas reserves for 2015, 2016 and 2017. The value of exploration properties and probable reserves, future exploration costs, future change in oil and gas prices and in production and development costs are excluded.
