This review of some of the major chemistry topics related to the oil and gas industry is divided into four sections. It looks in turn at the latest developments in environmental issues, new technology, applications and flow assurance. This reflects the increasingly important role for chemical technologies in offshore, deep water and challenging environments, allied to developments of low environmental impact chemistry. Regulatory strategies are also discussed, from both the governmental and operational perspective. Overall, Chemistry in the Oil Industry VII presents information on developments in the modern oil industry, which will have an impact on future cost-effectiveness and efficiency. It should prove a useful resource for professionals and consultants within the industry, as well as government agencies and laboratory staff.
