Abstract
Summary
To Successfully Define Hydrocarbon Reservoirs And Characterize Reservoirs Of Different Types, Explorationists Need To Expand The Seismic Bandwidth From Current 3 Octaves (Say, 10–80 Hz) To 5–6 Octaves Toward Both Low And High Frequencies. To Acquire Such High-Resolution Seismic Data On Land, New Integrated Technologies Should Be Developed. These Technologies Includes Such Components As 1) Point-Source And Point-Receiver Acquisition, 2) Excitation And Recording A Wideband Signal, 3) High Spatial Sampling To Ensure Good Distribution Of Azimuths And Offsets In The Bins, 4) High Accuracy Of Source And Receiver Positioning.
