The Virtual Geoscience Center displays pictures of geophysical items that are on display or archived at the SEG Geoscience Center in Tulsa. Currently, the online collection has 144 on display. All of these instruments are loaned to the SEG Geoscience Center or have been donated by companies and individuals.

At the top-level, there are four basic types of items: magnetic, electrical, seismic and gravity instruments. You will find a description of these types of instruments in their appropriate section. We also have collected a gallery of "interesting" instruments or objects that do not fit into one of the four major categories as well as some historical information and photographs - you can check these out in the Gallery category.

We Need Your Help:

There are many pieces of information we store about each instrument besides the basic name-description couplet; for instance, its manufacturer and date, item number, and donor, if applicable. In many cases, you will find little or no information, just a picture or two.  We appreciate any assistance you can offer to identify some of these instruments. If you know any information about any instrument in our collection, have pictures showing the instrument being used in the field, have a question, would like to make a correction, do not hesitate to contact us.  On each item page, you will find a "Do You Know More" button.  Click this button to open up a form so that you can conveniently provide us with what you know. There are a few instruments that are total unknowns. We collected these "unknowns" into a separate page which you may access if you follow this link.
