Geophysics
- Geophysical data interpretation ranging from 2D-3D seismic, gravity, electrical resitivity tomograhy (ERT), electromagnetic (EM), and magnetotelluric (MT).
- Integration of geophysical and geological data (wells, outcrop data) together with regional geological knowledge ensuring a consistent and coherent conceptual model(s) and related uncertainties and alternative interpretation.
- Optimisation and cost-efficient solutions to achieve bottom-line results.
- Support in designing and processing services includinng 2D and 3D seismic surveys, gravity, electric electromagnetic data and passive seismicity monitoring.
- Signal enhancement, noise/signal optimisation and inversion
- Rock-physics analysis and AVO modelling.
GER’s uses extensive worldwide experience and large variety of analogues and techniques (i.e. seismic sequence stratigraphy, AI-assisted analogue assessment) to assist data interpretation.
Geophysical Acquisition Design, Permitting, Operations Supervision, as well as Seismic Processing and Re-Processing is carried out in collaboration with GER’s specialized partners
