This paper focuses on the most effective approach to defining additional resources using 3-D seismic as the sole data source. Although this example is from a densely drilled province, such a seismic-based approach is often used in frontier areas with sparse well coverage, in step-out regions around known production, can be used for a “quick look” evaluation of existing properties, and for real-time interpretation of newly acquired data.

This approach—integrating multiple seismic attributes and interpretation methods—refined the structural framework and detected undrilled prospective areas in a mature province in the Gulf of Mexico. Coherency technologies refined the fault interpretations. Surface...
