Abstract

The information accumulated by the exploration industry is rapidly increasing. The problem of storage and handling of this voluminous data is rapidly growing as more information is gathered and processed for interpretation. During 1977, for example, the industry recorded an estimated 1014 to 1015 bits of seismic data in digital form. Packed at 1600 bpi in the most efficient form, these data occupy nearly three million magnetic tapes, each 2400 ft long.

The seismic data recorded on these tapes are only the starting point in a series of highly sophisticated processes that culminate in graphic displays such as maps, cross-sections, and charts. These graphic displays are visually interpreted to map the subsurface geologic conditions existing in the geographic area represented by the data.

In this chapter, we discuss a graphics approach to exploration data base management. Also, we present some aspects of exploration activity in the perspective of an electronic data processing (EDP) exercise.

Acquiring and processing seismic information is only one facet of exploration activity; however, this should serve as an example of the procedures through which all other data advance in the process of becoming a meaningful resource to the exploration industry. The procedures outlined below and shown in Figure 1 concern a marine seismic operation.
