Web16 okt. 2024 · The seismic reflection interpretation was constrained and integrated with seismic refraction and resistivity tomography, and the one-dimensional multichannel analysis of surface waves to generate the model that best represents the real subsurface geological model. WebFirst consider the source-receiver geometry. The geometry can be “split spread” in which case there is a central shot with receivers on both sides, or a “single-ended spread” in which the receivers are always on one side of the source. Split spreads are common in land surveys; single-ended spreads are common in marine surveys.
