2D/3D Seismic surveys

Geotec S.p.A. specializes in onshore seismic acquisition for geophysical research and geological knowledge of the subsurface for oil and gas exploration and scientific aims or purposes.  Geotec S.p.A. is a national leader when carrying out geophysical surveys using the 2D/3D seismic reflection method. It is equipped with the most up to date, high-tech equipment and has at its disposal a vast fleet of vehicles (over 230) operated by highly qualified, experienced staff.

Geotec S.p.A. has been involved in very important scientific studies and geophysical surveys such as TRANSALP and the CROP project (CROSTA PROFONDA) and projects regarding CO2 storage together with the most well known European research bodies such as CNR – “Consiglio Nazionale delle Ricerche” (National Research Council), IFP – French Institute of Petroleum, OGS – “Instituto Nazionale di Oceanografia e Geofisica Sperimentale”  - National Institute of Oceanography and Experimental Geophysics, TNO The Netherlands Organization for Applied Scientific Research and Imperial College London , as well as other Italian Universities. 

ENI, STOGIT, SARAS, EDISON, OMV, ENEL, SNAM RETE GAS, are just some of the prestigious national and international companies for which Geotec S.p.A. provides services. 

Seismic reflection or refraction

This involves the measuring of waves reflected or refracted at interfaces between subsurface layers of different velocities (i.e. densities).  Seismic waves are either reflected or refracted and detected by instrumentation such as  a seismograph, sensors etc.  The choice of method is often dictated by site specific conditions or project goals and is, however, usually established by the Client.  Some of the reasons associated with the choice of one method as opposed to the other may be desired targets, site conditions, vertical and /or lateral resolutions, survey depth and budgetary constraints.

Possible applications

  • Stratigraphic reconstruction
  • To identify bedrock depths
  • For Lithostratigraphic correlations
  • Through surveys for construction in earthquake prone areas and studies regarding microzonation
  • For the study of landslides
  • To determine elastic constants (Young’s modulus, bulk’s modulus, stiffness, Poisson’s ratio)
