Union improves resolution, efficiency: A combination of two methods holds promise for faster land seismic acquisition

摘要

An experiment was conducted near the city of Alpine in West Texas to investigate a unique seismic acquisition technique. The potential of the technique involves the union of the High Fidelity Vibratory Seismic (HFVS) acquisition method with either the Slip-Sweep or the Concatenated method of Vibroseis acquisition. Among the benefits provided by HFVS recording is the ability to separate the sources during the processing of the seismic data. Source separation allows for enhanced spatial sampling, which improves the resolution and the bandwidth of the seismic image. Among the benefits of the Slip-Sweep or the Concatenated method of seismic acquisition is an increase in the production rate. An increase in the production rate can be used to collect data faster, or to acquire more seismic data per unit area, which can be used to improve spatial sampling or increase the fold. The new technique capitalizes on the benefits inherent in both methods.
