Should we invest in telemetry systems?

Abstract

Over the years we have experienced increasing numbers of recording channels in reflection seismic data acquisition systems, from 24 through 120 for technical and economic reasons. Perhaps maximum feasible achievable spread lengths have been attained, however, trends to high resolution techniques demand more channels at lesser station intervals for a given spread length. Also, trends to a real (3-D) techniques demand more channels although not necessarily at lesser station intervals.
