An effective approach to the global issue of chemical management, based on Gulf Coast and North Sea experience in wellbore stimulation, is described. This paper presents the results of aggressive chemical development and replacement programs for stimulation chemicals for worldwide application. Development of more environmentally acceptable products requires working with regulatory agencies, clients, and chemical suppliers to achieve regulatory compliance for MSDS, labels, and environmental testing protocol. This paper recognizes that international environmental statutes and guidelines combined with clear corporate goals to minimize environmental impact are key requirements in regulating industrial use and discharge of environmentally harmful chemicals. The development of more environmentally acceptable products requires a thorough screening of environmental fitness and status of compliance with relevant laws and regulations.

Oilfield chemicals have primary active ingredients that may be harmful if discharged to the environment. Improving the characteristics of these products to reduce risk or damage to marine life requires changes in previously acceptable products, such as elimination of restricted materials and incorporation of components with improved ecotoxicity values.

Details are given on the aggressive programs developed to address a wide range of environmental opportunities and issues. International environmental statutes and guidelines are the strongest driving force to restrict industrial use and discharge of environmentally harmful chemicals. The primary tool of environmental risk reduction is an aggressive product development program incorporating more environmentally friendly chemical solutions. The paper will also present three years of field results achieved using environmentally improved stimulation products.
