Integrated environmental monitoring Principal Researcher Vidar Hepsø Ph.D
Statoil RD Environmental Technologies
2 - Classification: Internal 2011-05-24
Paradigm shift
From “expeditionary” offline sampling
Gain licence to operate
by demonstrating prudent operations in sensitive areas
To continuous environmental monitoring

Current Practice - Monitoring regimes
To be carried out by independent 3rd party
• Point samples of selected physical/chemical and biological parameters
− Sediments
− Water column
− Soil
− Ground water
• Remote sensing
• Follow-up after spills
• Visual surveys
8 - Classification: Internal 2011-05-24
Current Practice - challenges
• Flexibility
− Monitoring must be suited to the actual habitat
− Physical sampling may harm sensitive habitats
• Response time of point sampling
− Significant time lag between impact occurrence and detection
• Cost-effectiveness
− Can be improved through integration in design and operations

Morvin, Norway
• Located in the Norwegian sea
• Area with cold water coral structures
• On-line monitoring before, during and after drilling
• Physical/chemical data
• Visual monitoring
• Real time monitoring proved no harm to the coral structure
