Abstract
In May 1990, the Norwegian Oil Industry Assn., Oljeindustriens Landsforening (OLF), commissioned a survey of chemical use in E and P activities in the North Sea. Ten operating companies and six chemical suppliers provided data on the specific types and quantities of chemicals used in their operations and the properties of those chemicals. These companies operated or supplied chemicals in the Norwegian, British, and Netherlands sectors. Technical discussions on the reasons for using chemicals and their application also were held. The comprehensive results of this survey are available from OLF as a report, with all chemical data on disk. This paper summarizes the primary observations from the OLF report. The quantitative uses are compared with previous summaries of quantities of chemicals used. Probable discharge quantities and concentrations are discussed. Acute aquatic toxicity data submitted by participants are presented and practical aspects discussed.
