Main Aspects of the Implementation of Seismic Projects

Abstract

The paper presents the planning and workflow of field seismic explorations. Seismic data acquisition has developed significantly over the last 15 20 years; the paper covers the most important changes and developments of this period and goes step-by-step through the process of implementing a land 3-D seismic project. In order to increase efficiency, the different cost reduction technologies appeared on the vibroseis source side in 3-D seismic, and wireless field technology is becoming more and more accepted among the forms of seismic data acquisition. The advances in seismic acquisition, including simultaneous source acquisition, wireless channel systems, and exponential growth in seismic channel count, are revolutionizing surveys. Improved receiver sampling along with high productivity are the drivers for seismic technology today, which means smaller, lighter and less power-hungry equipment, while also increasing channel counts, minimizing system related remediation and HSE risk. A new era in land 3-D seismic surveys has arrived in Europe and in Hungary, too. The author used her experience in the implementation of many domestic and foreign 2-D and 3-D land seismic projects as an observer, shift leader, field manager, and then as a project leader in Europe. She combines these practical experiences with specific aspects of field project design and implementation. The aspects covered in this paper contribute to the professionally efficient and financially profitable implementation of field projects.
