This document discusses how GIS can be used to increase efficiency and accuracy in oil spill planning and mitigation. It describes how GIS was used to streamline the financial responsibility assessment process for offshore drilling, reducing the work time from 4 hours to under 5 minutes, a 98% decrease. The document also outlines other areas where GIS could potentially be applied, such as environmental impact assessments, spill response planning, and pipeline routing. Overall, the document promotes the benefits of GIS for improving workflows and decision making in environmental management and regulation of offshore oil and gas operations.
