Schlumberger Oilfield Services

Schlumberger Oilfield Services is a provider of technology, project management and information solutions to the international oil and gas exploration and production industry. Schlumberger Oilfield Services manages its business through GeoMarket regions, which are grouped into four geographic areas: North America, Latin America, Europe/Commonwealth of Independent States/Africa, and Middle East and Asia. The GeoMarket structure offers customers a single point of contact at the local level for field operations and brings together geographically focused teams to meet local needs and deliver customized solutions. Schlumberger Oilfield Services operates many oilfield service markets covering the entire life cycle of the reservoir. These services are organized into eight technology-based product and service lines (Technologies) to capitalize on technical synergies and introduce solutions within the GeoMarket regions.

Wireline provides the information necessary to evaluate the subsurface formation rocks and fluids to plan and monitor well construction, and to monitor and evaluate production. Wireline offers both open-hole and cased-hole services. Drilling and Measurements supplies directional-drilling, measurements-while-drilling and logging-while-drilling services. Well Testing provides exploration and production pressure and flow-rate measurement services both at the surface and downhole. Well Services provides services used during oil and gas well drilling and completion, as well as those used to maintain optimal production throughout the life of a well. The services include pressure pumping, well cementing and stimulation operations, as well as intervention activities. The Technology also develops coiled-tubing equipment and services

Completions provide completion services and equipment that include gas-lift and safety valves, as well as a range of intelligent well completions technology and equipment. Artificial Lift provides production optimization services using electrical submersible pumps and associated equipment. Data and Consulting Services supplies measurement, interpretation and integration of all exploration and production data types, as well as expert consulting services for reservoir characterization, production enhancement, field development planning, and multi-disciplinary reservoir and production solutions. Schlumberger Information Solutions provides consulting, software, information management, and information technology (IT) infrastructure products and services that support oil and gas industry core operational processes.

Schlumberger Oilfield Services also offers customers its services through a business model known as Integrated Project Management (IPM). IPM combines the products and services of the Schlumberger Technologies with drilling rig management expertise and project management skills to provide a solution to well construction and production improvement. Schlumberger is a 40% owner in M-I Drilling Fluids, a joint venture with Smith International that offers drilling and completion fluids used to stabilize rock strata during the drilling process and minimize formation damage during completion and workover operations.

WesternGeco

WesternGeco provides reservoir imaging, monitoring and development services, with seismic crews and data processing centers in the industry, as well as a multi-client seismic library. Services range from three-dimensional (3D) and time-lapse four dimensional (4D) seismic surveys to multi-component surveys for delineating prospects and reservoir management. Seismic solutions include Q technology for enhanced reservoir description, characterization, and monitoring throughout the life of the field, from exploration through enhanced recovery. Other WesternGeco solutions include development of controlled-source electromagnetic and magneto-telluric surveys, and their integration with seismic data.

WesternGeco offers a range of technologies and services. Land Seismic provides resources for seismic data acquisition on land and across shallow-water transition zones. Marine Seismic provides seismic acquisition and processing system, as well as a carlibrated single-sensor marine seismic system. Multiclient Services supply seismic data from the multi-client data library. Reservoir Services provides the people, tools and technology to help customers capture the benefits of an integrated approach to locating, defining and monitoring the reservoir. Data Processing offers seismic data processing centers for complex data processing projects. Electromagnetics provides controlled-source electromagnetic and magneto-telluric data acquisition and processing.
