Abstract

A

In recent times, velocity surveys at marine well locations have been performed using non‐explosive energy sources such as air‐guns and gas guns. In addition, surveys in land wells have been successfully carried out using a modified version of the air‐gun. This paper illustrates some of the characteristics of these devices and compares the data obtained from typical surveys with conventional dynamite surveys.

Since data obtained from well velocity surveys using non‐explosive sources are now commonly recorded on tape, they lend themself to further digital processing and interpretation techniques that were not previously so conveniently available. Some examples of these processes, e.g. the examination of attenuation, frequency and energy content of the recorded well geophone signals, are given in the paper. Examples of some other digital processes, using calibrated Acoustic logs, whether recorded digitally in the field or subsequently converted from analogue recordings, are also given in the paper. These include the construction of an Acoustic log in the vertical axis from logs obtained in deviated wells.
