Offshore Oil & Gas Survey
De-risking Offshore Exploration with Underwater Glider Data Collection
With several Research and Development programs, ALSEAMAR offers a unique expertise for underwater exploration. Its expert team conducts global missions to provide accurate and timely data for research, environmental monitoring or commercial projects.
ALSEAMAR’s solutions are fast and easy to mobilize on site, cost-effective, and fully autonomous, significantly reducing HSE risks. With near real-time data transmission and mission management, as well as the ability to detect dissolved chemical compounds, ALSEAMAR ensures high-performance surveys with no environmental footprint.
Natural Seep Hunting
Seeps migrating in the water column through the seabed from deep reservoirs provide valuable information and help de-risk petroleum systems on early stages of exploration programs.
SEAEXPLORER glider’s technology detects and retrieves methane and hydrocarbons bubbles and droplets visuals all the way through the water column, from the seabed up to the surface.
Collected data and analysis
- Methane concentration
- Oil Proxies (PAH)
- Bubbles detection
- Salinity
- Temperature
- Pressure
- Turbidity
- Dissolved Organic Matter
- Currents
Features and benefits
- In-situ data to validate the interest of offshore seismic acquisition in a remote area
- Environmental follow up during the entire life of a project
- Efficient technology to assist with wildcat exploration, reservoir delineation, well placement
- Optimize seismic acquisition program to focus only on the most interesting areas
- Excellent threshold detection to enable full seeps visualisation
Plug and Abandonment Survey
The SEAEXPLORER capabilities provide valuable information to perform a complete environmental baseline study prior to and after P&A activities.
The glider technology collects accurate biological and physical parameters to provide with a full environmental picture.
By detecting hydrocarbons released into the water column, ALSEAMAR also ensures wells are correctly plugged and shows no leakage.

Oil Spill Response
ALSEAMAR’s technology, methods, management systems and experience are ideally suited to monitoring studies to help manage an environmental emergency response to an oil spill.
The SEAEXPLORER’s efficient real-time data collection and processing capabilities enable large areas to be surveyed accurately and rapidly before an impact occurs. Equipment and crew can be mobilized at short notice anywhere in the world.
Collected data and analysis
- Oil slick concentration
- Oil spill movements
Features and benefits
- Visualize the concentration of the oil slick underwater thanks to surveys from the surface down to over a thousand meters
- Help forecast future oil spill movements
- Contribute to a comprehensive and appropriate response to help manage an environmental emergency
