Abstract
Summary
Coil based geophones are proven to be a reliable technology that has been used in land data acquisition for a long time. However, to better acquire both low and high frequency data, it seems that the limitations of conventional geophones are reached. This paper attempts to present a new designed geophone accelerometer using closed-loop controlled dual-coil geophones. Field tests show that the new designed geophone accelerometer provides geophysical benefits in terms of frequency bandwidth, especially low frequency recording.
