Opseis telemetry

Abstract

The elimination of the heavy cumbersome multi-pair cables between the geophone stations and the recording unit has been long awaited. Stepped-up exploration activity for new oil and gas reserves has made the industry more sensitive to this need, primarily since the search leads increasingly toward difficult areas where cable recording systems are less economically feasible. Reliable, high-fidelity two-way radio links were required that would allow command-response operations. Only as state-of-the-art advancements occurred in digital radio frequency (RF) techniques in the last few years has transmission of seismic data with the dynamic range and resolution qualities demanded by today's needs been possible.
