ONEOK is a Fortune 500 company based in the United States that operates in the energy industry. It is primarily engaged in the gathering, processing, storage, and transportation of natural gas and natural gas liquids (NGLs). Headquartered in Tulsa, Oklahoma, ONEOK has an extensive network of assets and facilities, enabling it to serve customers across the United States.

The company has a rich history that dates back to 1906 when it was established as Oklahoma Natural Gas Company. Over the years, it underwent several name changes and acquisitions before becoming ONEOK in 1980. The company's headquarters in Tulsa, known as the ONEOK Plaza, consists of multiple high-rise buildings and serves as the hub for its corporate operations.

ONEOK offers a wide range of products and services to its customers. It operates pipelines, storage facilities, and processing plants that gather and transport natural gas and NGLs. The company also provides NGL fractionation and marketing services, as well as natural gas distribution services to residential, commercial, and industrial customers.

On a global scale, ONEOK primarily operates within the United States and does not have significant international operations. However, the company has formed strategic partnerships and joint ventures with other industry players to expand its reach. Notably, it has a joint venture with a subsidiary of Williams Companies called Overland Pass Pipeline Company, which provides transportation services for natural gas liquids.

ONEOK holds a strong market position in the energy industry, particularly in the natural gas and NGLs sectors. The company is one of the largest publicly traded energy infrastructure companies in the United States and is recognized for its extensive pipeline network and storage capacity. It competes with other major players such as Enterprise Products Partners and Kinder Morgan.

In terms of major events, ONEOK completed a significant acquisition in 2017 with the purchase of all outstanding common units of ONEOK Partners, simplifying the corporate structure and enhancing its operational efficiency. This strategic move further solidified ONEOK's position as a leading energy company in the United States, enabling it to offer integrated services to its customers. Currently, ONEOK continues to focus on expanding its infrastructure and investing in organic growth projects.

The company aims to capitalize on the increasing demand for natural gas and NGLs by expanding its pipeline network and developing new assets. As of the latest updates, ONEOK is well-positioned for future growth and remains committed to delivering value for its stakeholders in the evolving energy market
