Griffie has been named senior vice president of operations and engineering, Robert W. Bourne has been named senior vice president and chief commercial officer and Catherine A.

"I am excited to add the remaining members of the Western Midstream management team as we transition into our next stage of growth," said CEO Michael P. Ure. "I have the utmost confidence the assembled management team will focus on enhancing the value of WES's premier asset footprint, which is well-positioned to support Occidental's U.S. onshore development plans in the Delaware and D-J basins and to attract sustainable third-party volumes by leveraging our existing midstream infrastructure to establish WES as a preferred midstream service provider for all producers."

At Anadarko, Griffie held various operational leadership positions including U.S. onshore business adviser, Eagle Ford operations manager, Appalachian Basin midstream manager, director of midstream engineering, and most recently as senior vice president of U.S. onshore field operations upon returning to Anadarko from Huntley & Huntley Energy Exploration where he served as senior vice president of midstream and marketing from June 2016 to December 2018.

Bourne led midstream corporate development efforts at Shell Trading (formerly Coral Energy), American Midstream Partners, Gas Solutions, Energy Transfer Partners, and Crosstex Energy (now EnLink Midstream). Most recently, Bourne served as vice president of business development, midstream and marketing at Apache Corp, and as a director of Altus Midstream Co.

Green has more than 20 years of accounting and audit experience and joined Anadarko in 2001. During her 18 years at Anadarko, Green has served in a variety of diverse roles within Anadarko's accounting and finance organization including internal audit, technical U.S. GAAP accounting, internal controls, and most recently as director of expenditure accounting.
