SEISMIC TOMOGRAPHY

We have been involved in several traditional tomography projects.

Geomap Norge has a long experience in carrying out seismic tomography surveys in horisontal and vertical boreholes. We have fine tuned our practical and theoretical knowledge in these years and we have created our specialised equipments for seismic tomography.

Our equipment park: 

  • 1700 meter borehole cable with 24 hydrophones(10 meter hydrophone distance), active part 230 meter and 1500 meter lead in, can be used in up to 72 mm diameter boreholes.

  • 1000 meter seismic water bottom cable with 48 hydrophones (10 meter hydrophone distance), 470 meter active part and 500 meter lead in. 

  • 500 meter seismic water bottom calbe with 48 hydrophones (5 meter hydrophone distance), 235 meter active part and 300 meter lead in. 

  • 4000 meter glassfiber cable in different dimensions for dynamite lead in into boreholes.

A new way of carrying out tomography in a 1600 meter borehole

Both of our water bottom cable can be extended with 500 meter lead in cable. Thus, their total length are respectively: 1500 meter and 1000 meter. 

Utstyret vårt fra borhullskabel, glassfiber kabler, hydrauliske motorer, tellehjul for posisjonering og skytekabler for borhullet samt arbeidstelt er spesialtilpasset formålet for seismisk tomografi. Furthermore, we use our own software for hydrophone positioning and modelling seismic tomography.

Geomap Norge has a cooperation with Geovista AB in regards of seismic tomography. I hovedsak med Håkan Mattsson, Fil Dr i Tillämpad Geofysikk.
