The Impact of 3-D Seismic in Exploration and Production

JOHNSON, DAVID A., Shell Oil Company, Houston, TX

The use of 3-D seismic in the United States grew dramatically during the decade of the 1980s. Examples are given showing that the 3-D tool has become an indispensable aid in developing new reserves optimally. Not only can the field extent be structurally defined, but detailed fault patterns can be used to optimize drainage points. Attribute analysis can define stratigraphic variations and pinch-outs within each reservoir unit. Timely incorporation of 3-D results in the development cycle reduces costs and adds additional reserves. Three-dimensional seismic is not also being broadly used as an exploration tool either prior to leasing or prior to drilling a prospect. Large speculative 3-D surveys have been conducted over parts of the Gulf of Mexico. The economics and results of these sur eys, as well as future trends, are discussed.
