Company Profile

Oil States International, Inc. (OSI), a global entity operating via its various subsidiaries, delivers a comprehensive suite of products and services tailored for the worldwide oil and gas industry. Its offerings span critical areas such as drilling, completion, subsea operations, production, and infrastructure development. The company's operations are structured into three distinct divisions: Well Site Services, Downhole Technologies, and Offshore/Manufactured Products. The Well Site Services division is responsible for providing diverse equipment and related services essential for the entire lifespan of oil and natural gas wells, from initial drilling to maintaining production. This includes specialized support for tasks such as isolating wellheads, managing frac valves, supporting wireline and coiled tubing operations, performing flowback and well testing, retrieving pipes, implementing gravel pack and sand control solutions, supplying blowout preventers, and conducting general drilling activities. Focusing on subsurface operations, the Downhole Technologies segment delivers advanced perforation systems and a variety of downhole instrumentation. These are crucial for well completion, intervention, wireline applications, and decommissioning activities. Furthermore, this segment is involved in the design, production, and commercialization of engineered consumable products, catering to both oilfield service providers and exploration and production firms. The Offshore/Manufactured Products division concentrates on developing, producing, and distributing significant capital equipment for various offshore applications, including gear for floating production platforms, subsea pipeline networks, and offshore drilling vessels and rigs. Key offerings within this category encompass flexible bearings, sophisticated connector solutions, high-pressure riser assemblies, deepwater mooring apparatus, specialized cranes, items for subsea pipelines, and integrated blowout preventer stack components. Beyond capital equipment, this segment also supplies short-lifecycle products, such as valves, elastomeric components, and other specialized items primarily for land-based drilling and completion activities. Additionally, it produces diverse products for industrial, military, and other general applications. Complementing its product lines, the division delivers an array of services, including specialized welding, fabrication, cladding, machining, offshore installation, and comprehensive inspection and repair.
