Founded2005

Western Refinery Services, historically known and operating primarily as Western Refining (formerly NYSE: WNR), was an independent crude oil refiner and marketer of petroleum products. The company's operations were concentrated in the Southwestern United States, including refineries in Texas and New Mexico, and also expanded to the Upper Midwest and Mid-Atlantic through acquisitions. Western Refining was acquired by Tesoro Corporation in 2017. Tesoro subsequently rebranded as Andeavor, which was then acquired by Marathon Petroleum Corporation (MPC) in 2018. Therefore, the assets and operations of what was Western Refinery Services are now part of Marathon Petroleum.

HQ Function

The El Paso headquarters housed executive leadership, corporate finance, legal, human resources, and strategic planning for the independent refining and marketing operations.

Notable Features:

The headquarters was likely a modern office facility typical for a mid-sized publicly traded energy company, focused on functionality and accessibility for corporate staff. Specific architectural details are not widely publicized post-acquisition.

Work Culture:

As an independent refiner, the work culture at Western Refining likely emphasized operational efficiency, safety, market responsiveness, and financial discipline. Employees would have experienced a dynamic environment focused on the volatile energy markets. Post-acquisition, the culture would have merged with that of Tesoro/Andeavor and subsequently Marathon Petroleum.

HQ Significance:

The El Paso headquarters was significant as the nerve center for a key regional refining player in the U.S., overseeing multiple refineries and a network of retail fuel stations and convenience stores, particularly in the Southwest.

Values Reflected in HQ: The headquarters would have reflected values of professionalism, operational focus, and commitment to the energy sector and the communities it served.

Location:

Prior to its acquisition, Western Refining's operations were primarily focused within the United States. Its core activities included oil refining in the Southwest (Texas, New Mexico), the Upper Midwest (Minnesota), and the Mid-Atlantic (Virginia), along with associated logistics and marketing operations. While it sourced crude oil internationally and sold some products with cross-border implications (e.g., to northern Mexico), it did not maintain a significant physical global presence with international offices in the way a multinational corporation might.
