During the years 2018 and 2019, the international oil price droppedsharply by 35% in the fourth quarter of 2018, followed by an increase of 27% in the firstquarter of 2019 and a 2.70% drop in the second quarter of 2019. According to the estimation– 12 –

LETTER FROM THE BOARDin EIA’s short term energy forecast dated 5 September 2019, the Brent oil price will beUSD 63.39/bbl for the year 2019 and USD 62.00/bbl for the year 2020, featuring a slow butsteady increase in the oil price as a whole. Following the rising oil prices, the capitalexpenditure in upstream oil exploration and production will also increase.According to IHS Markit’s data, the global expenditure in offshore exploration hasincreased significantly and is expected to remain a 10% annual increase for the followingyears. Along with the rising global capital expenditure in the international market, theCNOOC Group will continue to increase their overseas investment in the future. Inconsideration of the “Seven-year Action Plan” of the CNOOC Group and CNOOC’soperation arrangement to “increase reserve and promote production”, the Company expectthat the domestic and overseas operation volume of the Company from the CNOOC Groupwill continue to increase in the next three years. Therefore, the market anticipates that oilprices will increase during the next three years, and capital expenditure of the CNOOCGroup in exploration and production activities in offshore China will also increase. TheCompany has compared the Company’s past performance with the performance of theCompany’s peers and the industry reports published by IHS Markit, and the Company is ofthe view that the Company has been prepared for the continuous increase of the businessvolume. Therefore, the historical transaction amounts for the two years ended 31 December2017 and 2018 and six months ended 30 June 2019 as a whole are valuable indicators forfuture transaction amounts during the next three years, and the anticipated business volumebetween the Group and the CNOOC Group for the three years ending 31 December 2020,2021 and 2022 will also increase which is in line with the capital expenditure of theCNOOC Group. The year on year growth rate of Proposed Annual Caps for the three yearsending 31 December 2020, 2021 and 2022 is also consistent with the expected trend of oilprices and the capital expenditure of the CNOOC Group.Additionally, the Company estimates that its revenues from other customers will alsoincrease during the next three years. The provision by the Group of the Oilfield Services tothe CNOOC Group during the two years ended 31 December 2017 and 2018 representedapproximately 78% of the total revenue of the Group. Since the Oilfield Services have beenthe main contributor to the Group’s revenue, as such, the proposed annual caps and theactual historical transaction amounts being at a similar percentage against the total revenueof the respective period is an appropriate basis to assess the fairness and reasonableness ofthe proposed annual caps. Hence, the Company has used the same percentage to estimateproposed annual caps. Considering the future capital expenditure plan of the CNOOC Group,it is estimated that the percentage of revenue from the Continuing Connected Transactionsduring the three years 2020 to 2022 will be slightly higher than that of the year 2019.Therefore, 83%, increased on the basis of 81% contribution by the Continuing ConnectedTransactions in the total revenue in the first half of 2019, will be used for the estimation ofthe percentage contribution of the proposed annual caps.As for the cost of the Continuing Connected Transactions, considering that theCompany’s operation model will not face significant change and that the cost from theMachinery Leasing, Equipment, Material and Utilities Services and the Property Servicesprovided by the CNOOC Group to the Group will remain relatively stable, the Companyexpects that the percentage of costs from the Continuing Connected Transactions in the totalcost of the Group will not encounter any major changes. Therefore, the Company made the– 13 –
