What Oil States Energy Services. does

Oil States Energy Services (OSES) is a Houston-headquartered, North American-focused equipment rental and service company operating within the upstream oil and gas completions, intervention, and workover segments. The company is a wholly-owned operating subsidiary of Oil States International, Inc. (NYSE: OIS). OSES rents specialized well intervention tooling — wireline support equipment, wellhead and tubing isolation tools, frac stacks, ball launchers, sand-control and gravel-pack assemblies, and production-services equipment — to oil and gas operators and oilfield service companies during the production, completion, and workover phases of a well's lifecycle. According to the company, it is the world's largest supplier of wellhead isolation equipment and offers the broadest range of rental tools for both onshore and offshore operations.

The product portfolio rests on a series of proprietary, in-house-developed technologies. Core engineering platforms include the ACTIVE*Hub™ wireless command-and-control platform with its ACTIVE*Latch™ 15,000-psi remotely operated wellhead connection, the Active Seat Gate Valve (a self-energizing fracturing valve qualified to API 6A PR2 with an 85% grease-use reduction), the patented Ball Launcher for multi-stage stimulation, the Top Entry Access System (TEAS) and Articulated Top Entry System (A-TES) for wireline access through top drives, and the Tempress Technologies suite of thru-tubing tools including the HydroPull® milling tool and Motor Gas Separator (MGS) for extreme-reach horizontal wells. Pressure-testing capability extends to 20,000–30,000 psi across the frac stack and isolation lines. The company operates an ISO 9001:2015 certified QHSE function and supports its equipment with API 6A-conformant quality programs.

OSES monetizes through equipment rental (recurring rental contracts) and 24/7 field service and support, priced on a quote basis tied to job specifications. Distribution is via direct enterprise field sales backed by a network of district offices co-located with active fracturing operations across the U.S. Gulf Coast (Louisiana), Mid Continent (Oklahoma), Rockies (Wyoming, North Dakota, Colorado) and Canada (Alberta), plus a manufacturing facility in Oklahoma City. The customer base consists of oil and gas operators and oilfield service companies requiring specialized intervention, completion, and pressure-pumping rental tools. Most recently, in February 2024, OSES introduced automated remote wellsite monitoring technology at HFTC 2024, extending its digital capability stack.

OSES is the world's largest supplier of wellhead isolation equipment, serving operators and service companies requiring pressure control during well intervention.
• Frac Stacks Rental equipment that temporarily replaces the production wellhead during pressure pumping operations, protecting operator production wellheads from pressure and abrasion during fracturing. Includes frac valves, gate valves, manifolds, and blow-out preventers rated up to 20,000 psi, manufactured to API standards with ISO-compliant QA.
• Ball Launchers Patented, remotely controlled ball drop mechanism for multi-stage well stimulation. Single-stack tube with 28-ball capacity dispenses balls automatically into the wellbore during fracturing stages, reducing errors and service interruptions with computer-generated job reports.
• Sand Control (Gravel Pack) Complete line of rental tools for frac pack, sand control, and tubing conveyed perforating applications, integrating wireline and flow-back applications for completion and well-intervention operations. Includes wash pipe, tool baskets, frac heads, hydraulic chokes, and frac manifolds; equipment is API certified.

Used for extended-reach milling, well stimulation, downhole phase separation, and sand cleanouts.
• Articulated Top Entry System (A-TES) Provides direct alignment of wireline entry sub with drill pipe axis allowing unrestricted entry of wireline tool strings, featuring double O-ring sealed internal ball joints that transmit right-hand and left-hand torque under tension and pressure.
• Top Entry Access System (TEAS) Exclusive system allowing wireline access to drill pipe or tubing through the gooseneck connection in the top drive while preserving the ability to use the top drive to pull and torque pipe; reduces cable damage potential and increases safety during open hole cut and strip over operations.
• ActiveLatch (ACTIVE*Latch) 5 1/8-in., 15,000 psi remotely operated wellhead connection requiring no cables or hoses. Part of the ACTIVE*Hub platform for wireless communication and control, powered by on-board DC power pack with 15-second latching time, enabling personnel to operate safely outside the red zone.
• Active Seat Gate Valve Self-energizing fracturing valve using asymmetric pressure on the seat and sealing mechanism with self-energizing seals; reduces valve grease contamination by 85% and extends greasing maintenance intervals while keeping personnel out of the red zone. Available in 7-inch size rated for 10K and 15K psi operations; API 6A PR2 qualified.
