Multi-Sat Offshore Gravity

Getech’s Multi-Sat gravity data provide valuable structural insight for offshore exploration at a fraction of the cost of new terrestrial data acquisition.

Our new generation of satellite derived gravity data integrates information from six satellites, together with an innovative processing workflow honed over the last 25 years, to provide the most accurate & coherent gravity free from oceanographic effects and satellite track noise.

Getech’s proprietary processing algorithms significantly improve on the results produced by many leading research institutes.

In fact, our latest Multi-Sat data now offers resolution similar to that of traditional 2D shipborne gravity surveys – globally!

To illustrate this point, we compare 2D shipborne gravity data from an OGA survey in the North Sea against Getech’s Multi-Sat data.

Key Features:

  • coherent and self-consistent gravity for all offshore areas

  • innovative processing workflow removes oceanographic and satellite track noise

  • reliable solution, even close to shoreline

  • new global bathymetry compilation to generate robust Bouguer anomaly

  • 1 km grid data for all offshore areas and the world’s 20 largest inland lakes

  • comparable to 2D shipborne gravity surveys

  • complements Getech’s superior onshore, high-resolution gravity compilations
