Deepwater Operations

Integrating project preparation, prospect definition, drilling performance, and informed completions and production

Deepwater project managers are required to juggle time, cost, and quality commitments. To combat expensive spread rates, you need to employ advanced drilling and evaluation technologies to most efficiently reach the well’s target depth and meet the project objectives. Deepwater programs are challenged to drill fewer wells while maximizing well information extraction. The numerous technical challenges coupled with the economics of deepwater projects make it essential to get things right the first time.

That’s where the people of Schlumberger come in. We have the unique combination of deepwater experience, expertise, personnel development programs, technology, and global presence to help operators deliver successful projects.

Experienced people: The key to deepwater project success

Competent, multiskilled, certified people are a pillar of deepwater success. Our rigorous deepwater certification process ensures that only specially trained, experienced engineers are assigned to deepwater projects. We use an interactive system that records and tracks Schlumberger deepwater personnel from their first day of employment, mapping expertise and experience by

  • certification
  • training
  • customers
  • rigs
  • services
  • water depths.

This unique tool matches the best-qualified personnel to projects based on individual skill sets and experience rather than on personnel location. Familiarity with rig-specific activities and processes reduces the amount of learning required in the environment and improves service delivery.


And our deepwater-certified personnel never stop learning. They undergo a continual learning process in workshops and through hands-on experience to learn the latest domain concepts and theories.

Service coordination, project management, and operational continuity assurance

We apply our prior experience and local knowledge to your projects to help you navigate local regulatory requirements and take the best logistics decisions for working in remote locations. Breaking down communication silos and interfaces, one integrated service project manager (ISPM) coordinates activities, including with third-party providers.

Integrated services model that fits your needs

An integrated services model (ISM) is available when we work together on multiple services and extends to managing third-party services. There are multiple examples and variations of the ISM service and it is dependent on client and project needs and requirements.

Personnel and equipment continuity

We assign people, equipment, and resources according to the needs of each project. In some cases, dedicated personnel and downhole equipment will travel with the rig, and the local Schlumberger bases provide the technical support. This minimizes any equipment availability uncertainty and allows for full accountability.


Preparation and execution that accelerate startup

Proactive preparation reduces the potential for NPT and increases efficiency and safety of operations. Our project-startup guidelines define the steps required for your specific deepwater mobilization and encompass industry standards, regulatory requirements, operator specifications, and HSE operating standards. Operational aspects include

  • customer communication plan
  • specific deepwater project planning
  • equipment and people selection
  • Schlumberger business line and function interaction plan
  • service delivery and remote support
  • incident handling and escalation matrix
  • quality processes such as our Hazard Analysis and Risk Control Standard (HARC) and Drill the Well on Paper (DWOP).

We rank and plot risk exposure, complexity and processes, people and competency, and equipment on a readiness matrix. All parties are made aware of progress, which significantly reduces unplanned events, NPT, and operating costs over the long term.
