Reservoir Characterization Group

The Company's Reservoir Characterization Group consists of the principal technologies involved in finding and defining hydrocarbon resources. These include WesternGeco, Wireline, Testing & Process, Software Integrated Solutions (SIS) and Integrated Services Management (ISM). WesternGeco is a geophysical services supplier, providing reservoir imaging, monitoring and development services. WesternGeco provides measurements and images of subsurface geology and rock properties for both customer proprietary and multiclient surveys. WesternGeco offers the multi-client library.

Wireline provides the information necessary to evaluate subsurface formation rocks and fluids to plan and monitor well construction, and to monitor and evaluate well production. Wireline offers both openhole and cased-hole services, including wireline perforating. Slickline services provide downhole mechanical well intervention. Testing & Process provides exploration and production pressure and flow-rate measurement services both at the surface and downhole. Through its Process Systems offering, Testing & Process provides equipment for the upstream, midstream and downstream separation of oil, gas, and produced water and water injection systems. Testing & Process also provides tubing-conveyed perforating services.

SIS sells software and provides consulting, information management and information technology (IT) infrastructure services to customers in the oil and gas industry. SIS also offers expert consulting services for reservoir characterization, field development planning, as well as petrotechnical data services and training solutions. ISM provides coordination and management of its services, products, and third parties in projects around the world.

Drilling Group

The Company's Drilling Group consists of the principal technologies involved in the drilling and positioning of oil and gas wells and comprises Bits & Drilling Tools, M-I SWACO, Drilling & Measurements, Land Rigs and Integrated Drilling Services (IDS). Bits & Drilling Tools designs, manufactures and markets roller cone and fixed cutter drill bits for various environments. Drilling Tools includes a range of bottom-hole-assembly, borehole-enlargement technologies and impact tools, as well as a collection of tubulars and tubular services for oil and gas drilling operations. M-I SWACO is a supplier of drilling fluid systems engineered to expand drilling by anticipating fluids-related problems; fluid systems and specialty equipment designed to optimize wellbore productivity, and production technology solutions. M-I SWACO also provides engineered managed pressure drilling and underbalanced drilling solutions, as well as environmental services and products to manage waste volumes generated in both drilling and production operations.

Drilling & Measurements provides mud logging services for geological and drilling surveillance, directional drilling, measurement-while-drilling and logging-while-drilling services for various well profiles, as well as engineering support. Land Rigs provides land drilling rigs and related support services. The land drilling system represents an integrated drilling platform bringing together digitally enabled surface and downhole hardware combined with a common optimization software. IDS supplies various services necessary to construct or change the architecture (re-entry) of wells. IDS covers various aspects of well planning, well drilling, engineering, supervision, logistics, procurement and contracting of third parties, and drilling rig management.

Production Group

The Company's Production Group consists of principal technologies involved in the lifetime production of oil and gas reservoirs and includes Well Services, Completions, Artificial Lift, Integrated Production Services (IPS) and Schlumberger Production Management (SPM). Well Services provides services used during oil and gas well drilling and completion, as well as those used to maintain production. Such services include pressure pumping, well cementing and stimulation, and coiled tubing equipment for downhole mechanical well intervention, reservoir monitoring and downhole data acquisition. Completions supplies well completion services and equipment that include packers, safety valves, sand control technology, as well as a range of intelligent well completions technology and equipment.

Artificial Lift provides production equipment and optimization services using electrical submersible pumps, gas lift equipment, rod lift systems, progressing cavity pumps and surface horizontal pumping systems. Integrated Production Services offers the project scope necessary to abandon, maintain, or upsurge the production of single or multiple wells. All features of project planning are addressed and include well engineering, wellsite supervision, civil engineering, logistics, procurement, contracting of third parties, and workovers. Schlumberger Production Management is a business model for field production projects. This model combines the required services and products of the technologies with drilling rig management, specialized engineering and project management expertise to provide a solution to well construction.

Cameron Group

The Company's Cameron Group consists of principal technologies involved in pressure and flow control for drilling and intervention rigs, oil and gas wells and production facilities, and includes OneSubsea, Surface Systems, Drilling Systems, and Valves & Measurement. OneSubsea provides integrated solutions, products, systems and services for the subsea oil and gas market, including integrated subsea production systems involving wellheads, subsea trees, manifolds and flowline connectors, control systems, connectors and services designed to exploit reservoir recovery and extend the life of each field. OneSubsea offers integration and optimization of the entire production system over the life of the field by flow control expertise and process technologies with petrotechnical expertise, and reservoir and production technologies.

Surface Systems designs and manufactures onshore and offshore platform wellhead systems and processing solutions, including valves, chokes, actuators and Christmas trees, and provides services to oil and gas operators. Drilling Systems provides drilling equipment and services to shipyards, drilling contractors, exploration and production (E&P) companies and rental tool companies. The products fall into two categories: pressure control equipment and rotary drilling equipment. These products are designed for either onshore or offshore applications and include drilling equipment packages, blowout preventers (BOPs), BOP control systems, connectors, riser systems, valves and choke manifold systems, top drives, mud pumps, pipe handling equipment, rig designs and rig kits. Valves & Measurement serves portions of the upstream, midstream and downstream markets, and provides valve products and measurement systems that are used to control, direct and measure the flow of oil and gas as they are moved from wellheads through flow lines, gathering lines and transmission systems to refineries, petrochemical plants and industrial centers for processing.
