Exhibit 99.1

Shell Midstream Partners, L.P. Agrees to Acquire Additional Assets from Shell

HOUSTON, May 5, 2017 - Shell Midstream Partners, L.P. (NYSE: SHLX) entered into a purchase and sale agreement to acquire a 100% interest in the Refinery Gas Pipelines, Delta Pipeline and Na Kika Pipeline for $630 million from wholly owned subsidiaries of Shell.

The acquisition price reflects an approximate 8.4 times multiple of the assets’ forecasted next twelve months adjusted earnings before interest, taxes, depreciation and amortization. The acquisition is expected to be immediately accretive to unitholders. Shell Midstream Partners intends to fund the acquisition with a combination of borrowings under existing credit facilities and cash on hand. The acquisition is expected to close on or around May 10, 2017, subject to customary closing conditions.

Highlights of the acquired assets:

• Refinery Gas Pipelines: A network of approximately 100 miles of gas pipeline connecting multiple refineries and plants operated along the Gulf Coast to Shell Chemical sites, including Shell’s Norco refinery and Deer Park refinery. The pipelines transport a mix of methane, natural gas liquids and olefins. This is the first drop down of assets from outside of Shell Pipeline Company and represents an important milestone for Shell Midstream Partners.

• Delta Pipeline: An approximately 130-mile onshore pipeline aggregating volumes from five offshore pipelines including Shell Midstream Partners’ Odyssey Pipeline and the Na Kika Pipeline. This acquisition connects offshore oil production in the eastern corridor of the Gulf of Mexico to key onshore markets.

• Na Kika Pipeline: An approximately 80-mile offshore pipeline anchored by the Na Kika platform which serves as a host to eight different subsea fields and connects to the Delta Pipeline at Main Pass 69.

The terms of the acquisition were approved by the conflicts committee of the Board of Directors of the General Partner of Shell Midstream Partners, which is comprised entirely of independent directors. This committee was advised by Evercore Group, L.L.C. as to financial matters and Andrews Kurth Kenyon LLP as to legal matters.

relating to expected EBITDA, future cash flows and future growth, financing of the transaction, closing of the

transaction, and statements expressing management’s expectations, beliefs, estimates, forecasts, projections and

assumptions. You can identify our forward-looking statements by words such as “anticipate”, “believe”,

“risks”, “schedule”, “seek”, “target”, “could”, “may”, “should” or “would” or other similar expressions that

identifying important factors, though not necessarily all such factors, which could cause future outcomes to differ

materially from those set forth in forward-looking statements. In particular, expressed or implied statements

concerning future growth, future actions, closing and funding of acquisitions, future drop downs, volumes, capital

requirements, conditions or events, future impact of prior acquisitions, future operating results or the ability to

Forward-looking statements are not guarantees of performance. They involve risks, uncertainties and assumptions.

Future actions, conditions or events and future results of operations may differ materially from those expressed in

NON-GAAP FINANCIAL MEASURES

This press release includes the term Adjusted EBITDA. We believe that the presentation of Adjusted EBITDA provides useful information to investors in assessing our financial condition and results of operations. Adjusted EBITDA is a non-GAAP supplemental financial measure that management and external users of our condensed consolidated financial statements, such as industry analysts, investors, lenders and rating agencies, may use to assess:

• our operating performance as compared to other publicly traded partnerships in the midstream energy industry, without regard to historical cost basis or financing methods;

• the ability of our business to generate sufficient cash to support our decision to make distributions to our unitholders;

• our ability to incur and service debt and fund capital expenditures; and

• the viability of acquisitions and other capital expenditure projects and the returns on investment of various investment opportunities.

The GAAP measure most directly comparable to Adjusted EBITDA is net income. This non-GAAP measure should not be considered as an alternative to GAAP net income. Adjusted EBITDA has important limitations as an analytical tool because it excludes some but not all items that affect net income. It should not be considered in isolation or as a substitute for analysis of our results as reported under GAAP. Additionally, because Adjusted EBITDA may be defined differently by other companies in our industry, our definition of Adjusted EBITDA may not be comparable to similarly titled measures of other companies, thereby diminishing its utility.

References in this press release to Adjusted EBITDA refer to net income before income taxes, net interest expense, gain or loss from disposition of fixed assets, allowance oil reduction to net realizable value, and depreciation, amortization and accretion, plus cash distributed to Shell Midstream Partners, L.P. from equity investments for the applicable period, less income from equity investments. We define Adjusted EBITDA attributable to Shell Midstream Partners as Adjusted EBITDA less Adjusted EBITDA attributable to noncontrolling interests.
