Fugro has completed several high-resolution geophysical surveys in the US Gulf of Mexico for Shell International Exploration and Production Company. The project required data collection over multiple deepwater lease blocks in the greater Perdido and Mars development areas to support clearance of potential environmental, engineering, geological, and archaeological hazards ahead of planned drilling activities.
As the preferred contractor for this project, Fugro deployed a Hugin autonomous underwater vehicle (AUV) from its purpose-built survey vessel, Fugro Brasilis. The Hugin AUV is depth-rated to 3 km and equipped with a multibeam echosounder, side-scan sonar, and sub-bottom profiling sensors. As such, Fugro was able to acquire critical seabed information over the project area safely and efficiently, despite challenging water depths. Fugro also used a mix of onboard and in-house processing resources to meet an accelerated interpretation and reporting schedule.
The current work for Shell began in July and finished in early October. The completed project totals more than 8,500 km of survey data.
