Distinguished Instructor Short Course •Chapter 1 3D Data GeometriesIntroductionBecause of practical and economical considerations, 3D surveys are not acquired with complete and regular sampling of the spatial axes. The design of 3D surveys pres-ents many more degrees of freedom than does the design of 2D surveys, and it has no standard or unique solution. Design of 3D acquisition geometries is the result of many trade-offs among data quality, logistics, and cost. Furthermore, nominal designs com-monly must be modified to accommodate operational obstacles encountered in the field.Data-acquisition design and processing are becoming ever more connected, because characteristics of the acquisition geometry strongly influence the data processing. One must understand the principles of acquisition design if one is to understand many data-processing issues.The main goal of conventional acquisition design is to obtain an adequately and regularly sampled stacked cube that can be imaged accurately by poststack migration. Other important parameters are the minimum and maximum offsets. Minimum offset must be small enough to guarantee adequate coverage of shallow targets. Maximum offset must be large enough to allow accurate velocity estimates, which are necessary for both stacking and poststack imaging. However, in common acquisition geometries, sampling of the offset axes may be inadequate when the data require prestack process-ing that is more sophisticated prestack processing than simple stacking. Even application of standard dip moveout (DMO) (Chapter 4) may be problematic with some commonly used acquisition geometries. In such cases, the requirement that midpoint axes be ade-quately sampled is not sufficient, because offset and azimuth sampling also are impor-tant.Another important issue emerging in modern 3D survey design is subsurface illumi-nation, in which targets are imaged under increasingly complex overburden and where more control is required on amplitudes of the images. Complex wave propagation associ-ated with large contrasts in velocity (e.g., salt or basalt bodies) may cause data to illumi-nate the target only partially, even if the wavefield is sampled sufficiently at the surface. Because target illumination is related strongly to data offset and azimuth, a careful sur-vey design can improve image quality dramatically. Survey-modeling tools that analyze target illumination by ray tracing through an a priori model of the subsurface geology help guide the design process toward successful acquisition geometries. However, the usefulness of these tools is limited by how accurately the subsurface geology and the velocity model are known.Although there are no preset solutions to the problem of acquisition design, a few acquisition schemes commonly are used as templates to be adapted to individual sur-veys. Common marine- and land-acquisition geometries and their characteristics are discussed in this chapter.
