Acquiring The World’s Largest Onshore Nodal Seismic Survey Field Operations And Processing Perspectives On High Density Seismic Acquisition

This presentation aims to educate seismic practitioners about the practical aspects and business impact of high-density nodal acquisition using a real-world case study. We present and analyse operational information and workflows from the project including: crew size, composition, logistics and HSSE; source and receiver productivity; survey and seismic data QC; and data transcription, delivery and processing.

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.

The case for a nimble Node, towards a new land seismic receiver system with unlimited channels

This paper outlines the need for a receiver-side technology shift to overcome many of the existing hurdles that hinder the economic acquisition of quality land seismic, such as significant HSE exposure, limited channel count, difficult terrain access, long survey durations and high survey costs.

Comparison and integration of active and passive 3D surface wave measures around the Scrovegni Chapel

We performed surface-wave analysis of passive and active dense 3D data, acquired around the Scrovegni Chapel (Italy) for archaeological prospective. Phase velocity maps obtained from passive and active data were compared for the same frequency. A strategy for future joint (active and passive) analysis is finally suggested.

In this article, we outline the motivation behind the invention of a new generation of nodes.

Affordable high-density seismic for CO2 geological storage

Geothermal and CCUS are technologies used for many decades to support and complement the energy industry and are considered today essential technologies to realistically achieve a net zero carbon future.

A brief history of a disruptive nodal technology

Lately, nodal systems have been introduced, where the data is recorded internally in a battery powered sensor node. Removing the cables can make operations vastly more efficient, however the large size and weight of the current nodes, and their cost, have limited the operational benefits and made it difficult to increase the channel count. We present a new nodal system that overcome these issues.
