ROLL-ALONG AND DROP-ALONG SEISMIC TECHNIQUES
Lorenz Shock · Geophysics · 1963
Abstract The designation “Roll-Along” is used to indicate the use of horizontal-data-stacking techniques when field data are derived by the shooting method. The term “Drop-Along” is used for weight-drop data. These methods have proven valuable in obtaining usable data in areas where the standard pattern techniques are ineffective, or where extreme multiplicity requirements make patterns economically impractical. Operational techniques have been developed for both Roll-Along and Drop-Along in which standard field recording equipment and cables are utilized. A discussion of these techniques and the associated data processing operations is presented. Record-sections are used to illustrate the quality of data obtainable by these methods and to compare it to pattern shooting.
