The purpose of this book is to provide insight into various aspects of land based petroleum activities from the exploration, drilling and field development through to the production and transportation, and finally the termination and restoration of a field. The book points approaches and practices used through the different life cycle phases of a field to reduce the environmental and social impacts of activities. These include environmental, HSE and risk management systems, life cycle planning, and the use of standards and indicators to communicate impacts. In addition, a few examples of available technologies are presented. The book is divided into three main sections: Section 1. The oil industry and sustainability challenges Section 2. Overview of environmental and social aspects and potential impacts during the life cycle of an oil field; Section 3. Impacts on regulations, management systems and communication.
