Innovation in
hydrocarbon sniffing
for offshore exploration
M. Masson, V. Rochet

2. RATIONALE BEHIND METHANE SNIFFING
Gas bubbles or oil drops release methane into water
Dissolved gas spreads out faster than oil or farther away than bubbles
Methane plume followed over 80 km from source (Gharib et al 2005)
Methane since 50 years as proxy for gas and oil seeps (Sackett 1977)

3. TRADITIONAL SNIFFING
Requires ship and specialized operators
Expensive
Heavy
Limited range
Maintenance

4. INNOVATION IN VEHICLES gliders
Autonomous
Low cost
Compact

5. INNOVATION IN SENSING laser-based methane sniffer
Long-term stability
Maintenance free
High sensitivity
Small size

6. LONG RANGE AUTONOMOUS SNIFFING

7. NEXT INNOVATIONS
Multi-gas and isotopes for finger-printing, reservoir characterization, oil content
Smart systems with adaptive behaviour
