It is Schlumberger’s Policy to conduct its worldwide businesses in a manner which assures
optimum protection of the environment. In addition to careful compliance with relevant laws
and regulations, efficient use of natural resources and waste reduction are keys to
achieving this objective.
This policy commits us to provide regular training to all employees, improve our technology
and enlist the cooperation of our suppliers, customers and neighboring communities to build
better environmental practices.
This policy is further managed through:
Periodic Environmental Audits of all sites to ensure compliance with and continuous
improvement of operating standards,
Environmental Impact Assessment of new products, processes and operations,
Environmental Assessments performed in relation to business and/or real property
transactions to avoid exposure to environmental liabilities. These assessments are always
conducted under the responsibility of the Corporate Environmental and Legal functions.
In each company, it is the responsibility of Line Management, with the support of the HSE and
Legal organizations, to implement the Environmental Protection Policy.

Three issues for consideration:
The world’s environment is deteriorating.
Air pollution (earliest to 1950’s)
Water pollution (1960’s to 1970’s)
Soil pollution (1970’s to 1980’s)
