Magellan Midstream Partners's Overview

Total employees854
HeadquartersTulsa
Founded

Magellan Midstream Partners, L.P. was a publicly traded American limited partnership primarily engaged in the transportation, storage, and distribution of refined petroleum products and crude oil. Its extensive asset portfolio included pipelines, storage facilities, and marine terminals, playing a significant role in the U.S. energy infrastructure. Key operations focused on the refined products pipeline system (the longest in the U.S.), crude oil pipelines and storage, and marine storage. In September 2023, Magellan Midstream Partners was acquired by ONEOK, Inc., and its assets and operations have since been integrated into ONEOK's broader energy portfolio.

Where is Magellan Midstream Partners's Headquarters?

HQ Function

The headquarters served as the central hub for Magellan's corporate functions, including executive leadership, financial management, operational oversight, legal affairs, human resources, and strategic planning for its extensive network of pipelines and terminals.

Notable Features:

The headquarters was located in One Williams Center, a prominent skyscraper in downtown Tulsa, known for housing major corporations and offering modern office facilities.

Work Culture:

The work culture at Magellan likely emphasized operational excellence, safety, regulatory compliance, and strong financial stewardship, typical of a leading entity in the midstream energy sector. It would have fostered a professional and results-driven environment focused on reliable energy delivery.

HQ Significance:

Tulsa, and specifically One Williams Center, was strategically important for Magellan, placing it at the heart of the energy industry and facilitating management of one of the nation's most critical refined products pipeline systems.

Values Reflected in HQ: The choice of a well-regarded, central location like One Williams Center likely reflected Magellan's commitment to operational stability, professionalism, and its significant role within the U.S. energy landscape.

Location:

Prior to its acquisition by ONEOK, Magellan Midstream Partners' operations were predominantly concentrated within the United States. Its vast network of pipelines, terminals, and storage facilities primarily served the central and southern regions of the U.S., connecting key crude oil production areas and refining centers to major consumption markets. While the products Magellan transported could be destined for global markets via export terminals it operated or served, the company itself did not maintain significant international operational offices or infrastructure under the Magellan name.

Executive changes at Magellan Midstream Partners over the past 12-18 months were dominated by its acquisition by ONEOK, Inc., finalized in September 2023.
