Well Intervention

Achieve the well access you require to ensure optimal production with our decades of field-proven experience and unmatched technology portfolio.

Project Execution

By identifying the best solution for your operations, we plan strategic, capability-enhancing project scopes that reduce vendor management and mitigate risk.

We deliver a one-stop-shop solution including vessel and ROV services, tooling, and well intervention solutions around the world.

Our rigless intervention and stimulation offerings provide the same high levels of control and reliability as rig-based operations, with less mobilization time and cost. We were the first to enable rigless subsea stimulation and we continue to introduce innovative solutions to meet your needs.

Subsea Hydraulic Well Intervention

We offer the industry’s most effective, safe, and reliable MSV-based hydraulic intervention solution, which has to date helped increase customer production by more than 15 million bbl.  

From start to finish, we collaborate with you to manage all aspects of an intervention operation to maximize flow and protect your subsea assets. Our project-specific solutions are built from our suite of products and service lines, including vessels, engineering analysis, tooling, ROVs, and project management.

Depending on the application, we select the best well stimulation tools for your operation—our tooling is deployed, operated, controlled, and retrieved from an MSV or rig, saving time and money.

Single-Well Acid Stimulation Case Study

Open-Water Coiled Tubing

Our open-water coiled tubing (CT) system serves as a high-volume conduit during riserless well intervention.

We offer both stand-alone CT packages and complete work packages, including vessel, ROV, tooling, and project management services. Using our open-water CT system for well stimulation, we have increased our customers’ productivity index (PI) up to 1,250%—from a pretreatment PI of 2 to a posttreatment PI of 25.

Our open-water CT deployment defines traditional CT requirements and overcomes limitations related to footprint (reduced up 40%), crew size (reduced up to 60%), pre-engineering (largely eliminated), and total cost.

Light Well Intervention

Enhance your production and resolve complex subsea challenges with our rigless, riserless light well intervention (LWI) systems.

IRIS and BORIS—our fully-integrated LWI solutions—offer the industry’s broadest functionality. We continue to set industry records in riserless LWI and have provided global customers with safe, cost effective well access for more than a decade.

Our systems are rated for water depths to 10,000 fsw (3,000 msw) and wellbore pressures to 10,000 psi. We incorporate a closed hydraulic system, patented grease injection/sealing system, and electric hydraulic controls in an in-house umbilical system. Our ROV-compatible services are suited for use with horizontal or vertical trees.

Company page Since our founding in the early 1960s, Oceaneering has expanded and grown globally to service several industries such as the offshore energy industry, defense, entertainment, material handling, aerospace, science, and renewable energy industries. In 1964, Mike Hughes and Johnny Johnson formed a Gulf of Mexico diving company called World Wide Divers. The company grew in response to increasing demand for their services and in 1969 merged with two other diving companies to form Oceaneering International, Inc. To solve the toughest challenges, we do things differently, creatively, and smarter. As your trusted partner, our unmatched experience and truly innovative portfolio of technologies and solutions give us the flexibility to adapt and evolve, regardless of market conditions. Our mission is to solve the unsolvable. We thrive by creating industry-changing technically creative solutions for the most complex operational challenges under water, on land, and in space. Our five core values establish a common culture and demonstrate what is most important for us as a company. Since the beginning, the company has transformed from a small regional diving company into a global provider of engineered products and services. Today, we develop products and services for use throughout the lifecycle of an offshore oilfield, from drilling to decommissioning. We operate the world's premier fleet of work class ROVs. Additionally, we are a leader in offshore oilfield maintenance services, umbilicals, subsea hardware, and tooling. We also serve the aerospace, defense, and theme park industries. Underpinning everything we do, safety is not only the foundation of our core values, but it is vital to our unmatched performance record and company culture. The industries we serve are as diverse as they are complex. Whether we are engineering deepwater umbilicals or developing robotics for aerospace applications, the safety and health of our employees, vendors, and customers is an integral part of our day-to-day business. If we are working, then our responsibility is to be working safely. Since our inception in 1964, we have placed a high value on employee safety—from diving services and subsea inspection to vessel-based installation operations. We have and will continue to evolve not only our health, safety, and environmental (HSE) processes, but those of the industries in which we work. Although we have been fatality-free since 1999, our HSE journey goes beyond statistics. As our portfolio of services has grown, we have continued to prioritize and advance our approach to HSE.
