Superior fracture characterization and better reservoir delineation are possible. The high-resolution spatial and temporal sampling, made possible by single-sensor acquisition techniques and DGF processing, allows the number of single sensors per group to be optimized where the SNR is low, thereby giving an optimum resolution image for deep targets. Where finer spatial sampling is required, such as in the imaging of steep dips or faults, the raw, ultrahigh-resolution single-sensor data can be used. When the reservoir image is crisper and fault edges are defined more accurately, reservoir delineation becomes easier for the interpreter, who now has a much more accurate subsurface image. In turn, the risk of committing to the selection of drill sites and wellbore trajectories on the basis of the interpreter's assumptions is reduced.
