Our industry is facing ever-shorter time frames to address a problem of increased complexity: maturing a prospect from initial access-level exploration into a de-risked mature prospect ready for well planting and drilling. Some of the challenges in this process come from handling of the sheer size of the regional-scale high quality seismic data sets that are now available, to the more mundane of managing the computer time needed to make high-fidelity images of the subsurface. Model building, which typically relies on human interaction, can also be a bottleneck in this process involving software platforms and time-consuming data logistics.

Recent advances in electronics now enable time-domain, or transient CSEM data, to be reliably acquired in an offshore environment and make the leap from its dominant position in land EM to the marine world. Multiple surveys using autonomous receiver nodes have successfully acquired marine time domain CSEM data. The approach has shown particular benefit in shallow water since the method records only the secondary fields and the signal is not dominated by the primary field.
