Today, our real-time technology services and solutions enable customers to translate acquired data into useful information, then transform this information into knowledge for improved decision making-anytime, anywhere. Harnessing information technology in this way offers enormous opportunities to enhance efficiency and productivity. This is a quantum leap from providing traditional 'just-in-case' information to delivering 'just-in-time' knowledge that meets the changing needs of our customers. International teamwork Reflecting our belief that diversity spurs creativity, collaboration, and understanding of customers' needs, we employ over 66,000 people of more than 140 nationalities working in 80 countries. Our employees are committed to working with our customers to create the highest level of added value. Knowledge communities and special interest groups with our organization enable teamwork and knowledge sharing unencumbered by geographic boundaries. Success without boundaries A tradition of excellence Each day, in 80 countries, we help our customers find and produce oil and gas with respect for the environment. We're looking for men and women to join our global family in this effort. We know the work is tough. But, if you're ambitious, innovative, and hard working, a Schlumberger career may be for you. You'll follow in the tradition of our founders, Conrad and Marcel Schlumberger, who transformed the energy industry with the revolutionary idea of using electrical measurements to map subsurface rock formations. Schlumberger engineers recorded the first electrical resistivity well log in Pechelbronn, France in September 1927. Their pioneering attitude has been the foundation of our success for almost 80 years, and why today Schlumberger is the world's leading oilfield services company. Now, there are new challenges as the demand for energy continues to increase. And new ideas, techniques, and solutions are necessary. As the search for hydrocarbons takes on ever greater importance, we have a multitude of career opportunities that will enable you to prove your abilities from the first day of work. We'll give you the training and support you need to take on our complex engineering and technical challenges.Schlumberger was founded on breakthrough technology more than 80 years ago.
