Revisiting the single sensor vs array debate in the light of new nodal system technology

Access now

How many single-sensor nodes should I replace my geophone array with? This is a question that resonates within the seismic acquisition community, especially with the emergence of nodal acquisition systems as contenders for high-channel-count seismic surveys.

Amine Ourabah delves into comparative data examples, discussing how this shift from geophone arrays to single-sensor nodes impacts seismic acquisition, processing, and the resulting seismic image.

Natural hydrogen exploration under the Pyrenees using a 3D multicomponent seismic array with autonomous nodes

Natural hydrogen exploration under the Pyrenees using a 3D multicomponent seismic array with autonomous nodes

Mainly generated by geological processes, Natural H2 has been observed with different degrees of purity as surface seepages or occasionally in wells targeting other resources. Although some distinct natural processes are known to generate hydrogen, exploring for it and understanding its presence remain a challenging task due to the lack of geological models and geophysical data.
