FOREWORDThe purpose of the Refraction Volume is to gather together the newer techniques of refraction seismic surveying into one volume for the Society of Exploration Geophysicists. An effort was made to make the information more easily available to those wishing to work with refraction methods. This volume contains a series of articles written principally by members of the SEG who are specialists in refraction techniques. The volume contains only new material, papers written and/or edited for this volume, with a bibliography of references to all other refraction material available to the editorial committee. The volume represents the efforts of a number of geophysicists over a period of several years.The use of the refraction method has had its ups and downs over the period of seismic exploration history. One of its particular high points was during the late 1950's. In the fall of 1960 it was decided to compile a refraction volume. At that time it was somewhat difficult to enlist authors who were able to obtain releases for their refraction material from their respective companies.In 1960-1961 a request was submitted to a number of people known to be interested in refraction work. This group of people was designated as the Refraction Volume Committee and is listed on a following page. They were requested to submit a list of topics which would be of interest to them in a Refraction Volume. Sixteen replies were received to this query, and some of them were quite comprehensive. The committee was then asked to submit one or more refraction papers or to approach members of their companies or other acquaintances to submit refraction papers that would cover some of the recommended topics.An outline of the Refraction Volume was formulated from the list of topics submitted by the Refraction Volume Committee, and from this outline a list of symbols was established. This list is included in the volume. The authors were asked to utilize this list so that common symbols would be established, making it easier for the reader to equate similar quantities from one paper to the next.Out of approximately 45 papers submitted, 31 were accepted and are included in this volume. The desirability of having refraction case histories was recognized, but very few of the papers submitted were of a case history type. Those that were submitted and are classified here as case histories generally represented relatively small amounts of refraction data, which were then compared with other geophysical methods, rather than being verified by the drill.Most of the papers submitted for this volume are of a "technique type," describing some particular interpretation technique that may be used for better interpretation of special refraction data. The very nature of refraction work lends itself to many interpretation techniques. Refraction surveying is a good procedure to solve particular problems and, in the hands of an expert, from it many things can be learned. A possible cause for the rise and fall of refraction utilization Was the flooding of the m...
