Overview
Oil States International is a United States-based provider of equipment and services for the oil and gas industry. Its activities have centered on the operational requirements of drilling, well completion, production, pipeline infrastructure, and offshore or subsea development. The company is publicly traded on the New York Stock Exchange under the symbol OIS. The business traces its origins to an oilfield supply store established in Tulsa, Oklahoma, in 1937. In 1942, it began selling rubber components to oilfield producers in Texas, helping establish an early specialization in products used in oil and gas operations. During the 1950s, the company also supplied rubber products for bridge-support applications, demonstrating that its industrial materials capabilities extended beyond the oil patch. During the 1970s, Oil States increasingly concentrated on the needs of oil and gas customers in Canada and along the United States Gulf Coast. In the 1980s, it expanded its focus on pipeline maintenance and repair associated with underwater operations. This development helped connect the company’s product portfolio with the infrastructure demands of offshore energy production, where specialized equipment must operate under high pressure and challenging environmental conditions. A significant expansion occurred in 1999, when Oil States acquired Tubular Services. The transaction strengthened its position as a major distributor of tubular products in the United States and broadened its role in the supply chain supporting drilling and well construction. Oil States completed its initial public offering in 2001 and began trading on the New York Stock Exchange as OIS. From 2005 onward, the company also acquired accommodation businesses serving oil and gas workers. These operations covered locations in Canada, including Fort McMurray, northern Alberta, and southern Saskatchewan, as well as Australia, including Gladstone in Queensland, Karratha in Western Australia, and the Gunnedah Basin in New South Wales. The accommodation portfolio became a separate public company, Civeo Corporation, through a spin-off completed on June 2, 2014. The transaction allowed Oil States to concentrate more directly on oilfield equipment and services while establishing Civeo as an independent provider of workforce accommodations. Oil States’ core market position is that of a specialized supplier rather than an exploration and production company. Its offerings have included wellhead and pressure-control equipment, subsea equipment, tubular products, and related services supporting the construction, completion, and operation of oil and gas wells. Demand for these products is influenced by drilling activity, offshore development, customer capital expenditure, commodity prices, and broader cycles in the energy industry. The company’s international exposure has included North American and Australian markets in addition to other oil and gas regions served through its business activities.
History
Oil States International began in 1937 as an oilfield supply store in Tulsa, Oklahoma. Its early development was tied to the expanding petroleum industry of the central and southern United States. In 1942, the business began selling rubber components to Texas oilfield producers. These products formed part of the consumable and replacement equipment required by drilling and production operators. During the 1950s, Oil States also supplied rubber products used in bridge-support applications. Although this work was outside the petroleum sector, it reflected the company’s broader industrial materials capabilities. Over subsequent decades, the company increasingly focused on oil and gas customers and on products that could be used in demanding field and infrastructure environments. In the 1970s, the business concentrated on serving oil and gas operations in Canada and along the United States Gulf Coast. These regions gave the company access to both land-based and offshore energy activity. In the 1980s, Oil States developed a stronger orientation toward pipeline maintenance and repair for underwater operations. The move supported its participation in offshore energy infrastructure, where subsea pipelines and related systems require specialized maintenance and equipment. Oil States expanded its distribution activities in 1999 through the acquisition of Tubular Services. Tubular goods are fundamental to well construction and production, and the acquisition helped make Oil States one of the significant tubular distributors in the United States. The company subsequently pursued a public-market structure, completing its initial public offering in 2001 and listing on the New York Stock Exchange under the ticker OIS. Beginning in 2005, Oil States acquired a series of accommodation inns serving oil and gas employees. The acquired locations included Fort McMurray and other areas of Alberta and Saskatchewan in Canada, together with sites in Queensland, Western Australia, and New South Wales in Australia. This business broadened the company beyond equipment and field services, but it remained connected to the energy sector because the accommodations served workers engaged in resource projects. The accommodation activities were separated from Oil States in a 2014 corporate transaction. On June 2, 2014, they became Civeo Corporation, an independent company listed on the New York Stock Exchange. The spin-off reduced the breadth of Oil States’ portfolio and enabled the remaining company to focus more directly on oilfield products and services. Oil States International’s continuing identity is that of an oilfield equipment and services supplier. Its portfolio has included wellhead equipment, pressure-control systems, subsea equipment, tubular products, and services supporting drilling, completion, production, and offshore infrastructure. Its business is exposed to the cyclical nature of the energy industry: customer spending, drilling activity, offshore development, commodity-price conditions, and regional oil and gas investment all influence demand. The company has operated primarily through North American and international energy markets and remains publicly traded as OIS.

Oil States’ wellhead offering forms part of its broader portfolio for operators and contractors managing well construction and production infrastructure.
Oilfield equipment
Pressure-control equipment
Pressure-control equipment is used to contain and manage the pressures encountered during drilling, completion, and production operations.
