Surface waves are easily generated by a seismic source, like a beating sledgehammer. Acquisition can occur with vertical energisation and the use of vertical geophones (ZVF), or with transverse energisation, using horizontal geophones (THF).[\/vc_column_text][vc_empty_space empty_h=&#8221;2&#8243;][vc_custom_heading heading_semantic=&#8221;h4&#8243;

uncode_shortcode_id=&#8221;992166&#8243;]Seismic refraction prospecting is a survey methodology for measuring how long elastic waves (P and S waves), generated at a source point, take to reach receivers (geophones), arranged along the surface of the land and aligned with energisation points. Distances between geophones and energisation points are established according to the thickness and types of material under investigation. In this way, the velocity of propagation of P and S waves and the thickness of layers crossed by them can be measured.<\/p>\n<p>The principle is based on the hypothesis that the subsoil consists of a limited number of flat\/parallel surfaces, each characterised by a constant seismic velocity, both vertically and laterally, and that velocity increased with depth.[\/vc_column_text][vc_empty_space empty_h=&#8221;2&#8243;][vc_custom_heading heading_semantic=&#8221;h4&#8243;

uncode_shortcode_id=&#8221;159665&#8243;]Seismic reflection prospecting is more complex than refraction seismic surveying, in terms of execution, data analysis and interpretation. It is a sophisticated surveying methodology used for reconstruction, as it provides higher resolution and greater depths of the stratigraphic structure of the area under investigation, for the detection of lateral lithological variations and study of geological structures like folds, faults, oil traps and profound instabilities. It is the most widely used geophysical prospecting method by the oil and geothermal industries, for exploring the subsoil.<\/p>\n<p>The use of this geophysical surveying technique, for the purpose of defining acquisition parameters, like the length of recording, sampling intervals, the distance between geophones, the type of stringing, far-offset or near-offset (to name but a few), shows just how crucial it is for us to be aware of &#8220;what we want to do&#8221;, which leads to &#8220;what we need to see it&#8221; and in turn &#8220;how can we obtain what we need to see it&#8221;. While a preliminary assessment of site characteristics and research objectives provides fundamental information on method applicability, nothing can replace the meticulous and expert analysis of field walkaway testing, which provides precious data.[\/vc_column_text][vc_empty_space empty_h=&#8221;2&#8243;][vc_custom_heading heading_semantic=&#8221;h4&#8243;

uncode_shortcode_id=&#8221;188679&#8243;]Seismograms acquired on the field are processed with the use of specialised and high performance software, to obtain the final stack section. The use of ultra-surface reflection techniques involves the identification and definition of the stratigraphic structure of geological bodies (stratification, depositional geometries, discordances, overthrusts, faults, cavities, etc.), of shallow to medium depth (from a few metres to 500 metres deep), and is one of the most effective surveying methods for the reconstruction of morphologies buried under the Earth&#8217;s surface.<br \/>\nIn any case, the ability to recognise the limits of the method, modify acquisition parameters, change equipment or end acquisition, are all professional characteristics of ours and a guarantee of quality.[\/vc_column_text][vc_single_image media=&#8221;104746&#8243;
