Schlumberger is the world's leading oilfield
services company supplying technology, information solutions
and integrated project management that optimize reservoir performance
for customers working in the oil and gas industry.
Schlumberger supplies a wide range of products
and services from seismic acquisition and processing; formation
evaluation; well testing and directional drilling to well cementing
and stimulation; artificial lift and well completions; and consulting,
software, and information management.
The company operates in 85 countries and employs over 120,000 people from more than 140 nationalities.
Schlumberger manages its business through 35 GeoMarket regions, which are grouped into four geographic areas: North America, Latin America, Europe & Africa, Russia, 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. Working together with the company's technology segments, the GeoMarkets provide a powerful conduit through which information and know-how flow to the customers, and through which Schlumberger engineers and geoscientists maximize technological synergies over the entire life of the field.
In 2014, the company reported revenues of $48.6 billion, up 7% from the previous year, and net income of $5.4 billion.
The company spent $1.21 billion on research and engineering in 2014.
Schlumberger has principal offices in Paris, Houston, London and The Hague.
Due to the sharp decline in oil prices, the company plans to cut 11,000 jobs this year or about 15% of its workforce since 2014.
