Client: Major oil company
Topic: Seismic and navigation processing QCs, acquisition QC, MMO and PAM for 3D towed streamer seismic

Situation

• Provided client representatives, MMOs PAM operators and PAM equipment
• Conduct a 3D towed streamer seismic survey
  
  

Challenges

• Undershoots of two platforms offshore Gabon
• Survey area situated in the close proximity to national park
• Shallow and deep water
• Fishing
• Humpback whales would be migrating to the area
  
  

Actions

• Seismic and navigation processing QC and liaison between client and contractor
• MMOs, PAM operators and PAM equipment to monitor cetaceans and turtles and shooting operations
• Interim and final reports for seismic processing QC, acquisition QC, navigation processing QC, MMO and PAM
• Seismic processing supervision post seismic acquisition
• Two platforms to be undershot resulting in several single boat close passes, requiring permission from the platforms
• Fresnel zone binning
• MultiSeis Project Manager software was used for production and timing logging and reporting as well as MultiPlot/SurveyWide
• Seismic data QC processing using ProMAX software to produce a suite of standard quality control products
• Four marine mammal observers were deployed so that there was continuous observation, two of which were passive acoustic monitoring observers using PAM equipment supplied by The Geo People
• Fishing was common during part of the survey and the MMOs helped spot fish aggregation devices in the water
  
  

Results

• Safe acquisition of acceptable seismic and positioning data
• Fully supervised seismic data processing post acquisition all the way through to the final processed dataset
• No incidences of non-compliance to the JNCC guidelines
