Abstract

Until recently, many of the innovations that have taken place in seismic imaging have been related to data processing, geostatistics and 4D seismic methods. Around three years ago, a new seismic acquisition technology was introduced to the industry: acquisition is generally the most expensive part of the seismic process and the new technology promised reduced costs and superior imaging. High quality seismic data reduces the risk in reservoir characterization and improves the final geologic model of the area. This new seismic acquisition paradigm is based on the use of VectorSeis 3C digital point-receivers, built on MEMS technology. The new sensor is dramatically different from its predecessor, the analog geophone, and some of the benefits include:
