Western Refining, Inc. was an independent crude oil refiner and marketer of petroleum products, operating primarily in the Southwestern and Upper Midwestern United States. Founded in 1992 and headquartered in El Paso, Texas, the company owned and operated refineries in Texas, New Mexico, and Minnesota. Its product portfolio included gasoline, diesel fuel, jet fuel, and asphalt. Western Refining also had a logistics business, Western Refining Logistics, LP (WNRL). In June 2017, Western Refining was acquired by Tesoro Corporation, which subsequently rebranded as Andeavor. Andeavor itself was then acquired by Marathon Petroleum Corporation in 2018. Today, the assets and operations of the former Western Refining are part of Marathon Petroleum.
Served as the central hub for executive leadership, corporate strategy, financial management, investor relations, and administrative oversight for all of Western Refining's operations and subsidiaries.
The headquarters likely consisted of modern corporate office facilities designed to support its executive and administrative functions. Specific architectural highlights were not widely publicized.
As a key player in the energy sector, the headquarters likely fostered a professional, performance-driven work environment. Emphasis was typically placed on operational efficiency, safety standards, market analysis, and strategic growth within the competitive refining industry.
The El Paso headquarters was pivotal for directing Western Refining's strategic initiatives, managing its refining assets, overseeing its marketing and logistics operations, and navigating the complexities of the energy market during its tenure as an independent company.
Prior to its acquisition, Western Refining's operations and assets were predominantly located in the United States. Its core business involved refining crude oil and marketing petroleum products within the Southwestern U.S. (Arizona, Colorado, New Mexico, Texas, Utah) and, after the acquisition of Northern Tier Energy, the Upper Midwest (Minnesota, Wisconsin, North Dakota, South Dakota). The company did not have a significant international operational presence in terms of owned refining assets or widespread global offices, although its products could have been part of broader market distribution.
