Recent advances have allowed development of micro electro mechanical system (MEMS) sensors with the sensitivity, low noise, and dynamic range needed in seismic acquisition. This is a possible “breakthrough” because MEMS accelerometers have the potential to provide broader bandwidth, more accurate amplitude, and less sensitivity to planting tilt than the coil-based geophones that have long been used in the industry.

Several papers have presented the advantages of three-component acquisition with single digital sensors based on MEMS, and the advent of these sensors has been promoted as the next big advance in land seismic acquisition—much like the shift to 24-bits recording...
