Exhibit 99.1

Section 13(r) Disclosure

Total S.A. has provided disclosure pursuant to Section 13(r) of the Securities Exchange Act of 1934 regarding certain Iran-related activities of its affiliates (collectively, the “Total Group”) during the 2017 calendar year, as set forth below. Total S.A. has stated that it believes that these activities are not sanctionable. Unless otherwise noted, all foreign currency translations to U.S. dollars in this exhibit are made using exchange rates as of December 31, 2017.

Exploration & Production

Following the suspension of certain international economic sanctions against Iran on January 16, 2016, the Total Group commenced various business development activities in Iran. Following the Heads of Agreement (“HOA”) signed on November 8, 2016 by National Iranian Oil Company (“NIOC”), Total E&P South Pars S.A.S. (“TEPSP”) (a wholly-owned affiliate of Total S.A.), CNPC International Ltd. (“CNPCI”) (a wholly-owned affiliate of China National Petroleum Company) and Petropars Ltd. (“Petropars”) (a wholly-owned affiliate of NIOC), these parties negotiated and then signed a 20-year risked service contract on July 3, 2017 (the “Risked Service Contract”) for the development and production of phase 11 of the South Pars gas field (“SP11”). The project is expected to have a production capacity of 2 Bcf/d or 400,000 boe/d including condensate, and to supply the Iranian domestic market starting in 2021. TEPSP (50.1%) is the operator of the SP11 project alongside CNPCI (30%) and Petropars (19.9%). These companies entered into a joint operating agreement in July 2017 concerning, among other things, the governance of their obligations under the Risked Service Contract and the designation of TEPSP as the project’s operator. A branch office of TEPSP was opened in 2017 in Tehran for this purpose.

The SP11 project is expected to be developed in two phases. The first phase, with an estimated cost of approximately $2 billion-equivalent, consists of 30 wells and 2 wellhead platforms connected to existing onshore treatment facilities by 2 subsea pipelines. Since the November 2016 HOA signature, Total S.A. has conducted engineering studies on behalf of the consortium and it initiated calls for tender during the third quarter of 2017 in order to award the contracts required to start developing the project in early 2018. At a later stage, once required by reservoir conditions, a second phase is expected to be launched involving the construction of offshore compression facilities.

The total required investment for the SP11 project is expected to be approximately $4 billion-equivalent, of which TEPSP would finance 50.1% via equity contributions and payments in non-U.S. currency. In the event of new or reinstated international economic sanctions, if such sanctions were to prevent TEPSP from performing under the Risked Service Contract, TEPSP expects to be able to withdraw from the Contract and recover its past costs from NIOC (unless such recovery is prevented by sanctions).

Also in 2017, the memorandum of understanding (“MOU”) entered into between Total S.A. and NIOC on January 16, 2016 to assess potential developments in Iran in compliance with remaining applicable international economic sanctions was amended to extend the MOU’s duration and include an additional potential oil and gas project, North Azadegan. In 2017, NIOC provided Total S.A. with technical data on the Azadegan oil field so that it could assess potential development of this field. Representatives of Total S.A. held technical meetings in 2017 with representatives of NIOC and its affiliated companies in 2017 and carried out a technical review of the Azadegan (South & North) oil field as well as the Iran LNG Project (a project contemplating a 10 Mt/y LNG production facility at Tombak Port on Iran’s Persian Gulf coast), the results of which were partially disclosed to NIOC and relevant affiliated companies. In addition, Total S.A. signed two MOUs in 2017 with two international companies to evaluate the Azadegan oil field opportunity with NIOC.

During 2017, in connection with anticipated activities under the aforementioned Risked Service Contract and MOUs, and to discuss other new project opportunities, representatives of Total S.A. attended meetings with the Iranian oil and gas ministry and several Iranian companies with ties to the government of Iran. After the signing ceremony of the Risked Service Contract, senior management of Total S.A. attended a meeting with the President of Iran. In connection with travel to Iran in 2017 by employees of the Total Group, Total S.A. made payments to Iranian authorities for visas, airport services, exit fees, and similar travel-related charges. In addition, representatives of Total S.A. had a meeting in France with the Iranian ambassador and hosted official visits in France of representatives from the Iran Ministry of Petroleum, NIOC, and affiliates of NIOC for demonstrations of Total S.A.’s technical capabilities and expertise.

Following the signature of a confidentiality agreement in late 2016 among the Oman Ministry of Oil and Gas, NIGEC (a subsidiary of NIOC) and a group of international companies, including Total S.A., representatives of the Total Group attended meetings in 2017 with the parties to the agreement, including NIGEC, to discuss a potential project for the construction, operation and maintenance of a pipeline to supply natural gas from Iran to Oman as well as to market such gas.

Neither revenues nor profits were recognized from any of the aforementioned activities in 2017, except that TEPSP received payments of approximately $15 million equivalent from its partners under the Risked Service Contract, including NIOC, for the reimbursement of their respective shares of past costs incurred by TEPSP under the HOA and their respective shares of the costs and expenditures incurred in 2017 under the Risked Service Contract.

Concerning payments to Iranian entities in 2017, Total Iran BV (100%) and TEPSP (on behalf of the SP11 project joint venture partners) collectively made payments of approximately IRR 7 billion (approximately $210,000) to (i) the Iranian administration for taxes and social security contributions concerning the personnel of the aforementioned branch office and residual buyback contract-related obligations, and (ii) Iranian public entities for payments with respect to the maintenance of the aforementioned branch office (e.g., utilities, telecommunications). Total S.A. expects similar types of payments to be made by these affiliates in 2018 albeit in higher amounts due to increased business development activity in Iran.

Furthermore, Total E&P UK Limited (“TEP UK”), a wholly-owned affiliate, holds a 43.25% interest in a joint venture at the Bruce field in the UK with BP Exploration Operating Company Limited (“BP”, 37%), BHP Billiton Petroleum Great Britain Ltd (16%) and Marubeni Oil & Gas (North Sea) Limited (3.75%). This joint venture is party to an agreement (the “Bruce Rhum Agreement”) governing certain transportation, processing and operation services provided to a joint venture at the Rhum field in the UK that is co-owned by BP (50% operator) and the Iranian Oil Company UK Ltd (“IOC”), a subsidiary of NIOC (50%). In 2017, TEP UK liaised directly with IOC concerning its interest in the Bruce Rhum Agreement and it provided services to IOC under the Bruce Rhum Agreement. TEP UK is also party to an agreement with BP whereby TEP UK shall under certain conditions use reasonable endeavors to export Rhum natural gas liquids from the St Fergus Terminal. TEP UK conducts activities pursuant to this agreement only when the primary export route for Rhum natural gas liquids is not available, and is subject to BP having title to all of the Rhum natural gas liquids to be exported, and a valid OFAC license for the activity. In 2017, the aforementioned activities generated for TEP UK gross revenue of approximately £3.9 million (approximately $5.3 million) and net profit of approximately £2.3 million (approximately $3.1 million). TEP UK expects to continue these activities in 2018.

Other segments

The Total Group does not own or operate any refineries or chemical plants in Iran and did not purchase Iranian hydrocarbons prior to 2016 when prohibited by applicable EU and U.S. economic sanctions.

The Total Group continued its trading activities with Iran in 2017 via its wholly-owned affiliate TOTSA TOTAL OIL TRADING SA, which purchased approximately 58 Mb of Iranian crude oil for nearly €2.6 billion (approximately $3.1 billion) pursuant to a mix of spot and term contracts. In connection with these purchases, CSSA Chartering and Shipping Services SA, a wholly-owned affiliate, chartered vessels owned by an entity with ties to the government of Iran to transport this crude oil. Total S.A. is not able to estimate the gross revenue and net profit related to these purchases, because most of this crude oil was used to supply the Total Group’s refineries. However, approximately 6.6 Mb of this crude oil were sold to entities outside of the Total Group. In addition, in 2017 approximately 14 Mb of petroleum products were bought from/sold to entities with ties to the government of Iran. These activities generated gross revenue of nearly €1.1 billion (approximately $1.3 billion) and a net loss of approximately €5.7 million (approximately $6.9 million). The Total Group expects to continue these activities in 2018.

Until December 2012, at which time it sold its entire interest, the Total Group held a 50% interest in the lubricants retail company Beh Total (now named Beh Tam) along with Behran Oil (50%), a company controlled by entities with ties to the government of Iran. As part of the sale of the Total Group’s interest in Beh Tam, Total S.A. agreed to license the trademark “Total” to Beh Tam for an initial 3-year period for the sale by Beh Tam of lubricants to domestic consumers in Iran. In 2014, Total E&P Iran (“TEPI”), a wholly-owned affiliate, received, on behalf of Total S.A., royalty payments of approximately IRR 24 billion (nearly $1 million) from Beh Tam for such license. These payments were based on Beh Tam’s sales of lubricants during the previous calendar year. In 2015, royalty payments were suspended notably due to a procedure brought by the Iranian tax authorities against TEPI. As of the end of 2017, no royalty payments had been received since 2015, but the payment of outstanding royalties in favor of Total S.A. is expected in 2018. In addition, representatives of Total Oil Asia-Pacific Ltd, a wholly-owned affiliate of Total S.A., made several visits to Behran Oil during 2017 regarding the potential purchase of 50% of the share capital of Beh Tam. As of the end of 2017, no agreement had been reached and no money was paid or received by either company. Further discussions are expected to take place in 2018.

Total Marketing Middle East FZE, a wholly-owned affiliate of Total S.A., sold lubricants to Beh Tam in 2017. The sale in 2017 of approximately 392 tons of lubricants and special fluids generated gross revenue of approximately AED 8.1 million (approximately $2.2 million) and net profit of approximately AED 3.7 million (approximately $1.0 million). Total Marketing Middle East FZE expects to continue this activity in 2018.

Total Marketing France (“TMF”), a company wholly-owned by TMS, provided in 2017 fuel payment cards to the Iranian embassy and delegation to UNESCO in France for use in the Total Group’s service stations.

Total Belgium expects to continue this activity in 2018.

Proxifuel, a wholly-owned affiliate of Total S.A., sold in 2017 domestic heating oil to the Iranian embassy in Brussels.

Total Lubrifiants may receive similar payments in 2018.

As a result of legal proceedings initiated in the United Kingdom by one of its suppliers against a Total S.A. affiliate based in India, Total Oil Private Limited (“TOIPL”), Total S.A. has recently concluded an investigation into the transactions, including into the facts and circumstances that follow. In January 2014, TOIPL received two spot contract shipments of LPG from a supplier based in Dubai. The vessel Scoter, which was owned by the National Iranian Tanker Company, was used to transport one of the shipments received by TOIPL. At the time of these transactions, India was the recipient of a waiver pursuant to Section 1245 (d)(4)(d) of the National Defense Authorization Act (“NDAA”). TOIPL has not paid the supplier for the shipments due to a contract dispute. The total value of the two contracts was $8.85 million, and the value of the shipment delivered aboard the Scoter was approximately $7.1 million. TOIPL’s LPG is stored in limited capacity storage facilities and contain LPG received from multiple suppliers. Therefore, it is not possible to provide a precise amount of gross revenue attributable to these spot contracts.
