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.

Our expert team conducts global missions to provide accurate and timely data for your research, environmental monitoring or commercial projects.

Natural seep hunting

Seeps migrating in the water column through the seabed from deep reservoirs provide valuable information and help to de-risk petroleum systems on early stages of your exploration programs. Marine natural seep hunting survey is an excellent mean to reduce risk and cost for your offshore campaigns.

Smart 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

  • Fast and easy to mobilize on site
  • Cost effective survey
  • No environmental footprint
  • Autonomous
  • Decreased HSE risk
  • Dissolved chemicals compounds detection
  • Near real time data transmission & mission management

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 in the water column, we also ensure wells are correctly plugged and show no leakage.
