Abstract

Prospect Cougar (South Timbalier 300 Field) is an oil and gas field located in 104 m (340 ft) of water, 105 km (65 mi) south of the Louisiana shore (Figure 14-3-1). Blocks S.T. 299, 300, and 301 were acquired by Shell in 1981, 1979, and 1977, respectively.

Cougar was one of Shell’s first fields to be covered by a 3-D seismic survey. Its position near the beginning of our 3-D learning curve, combined with the complex structure of the field, provides an interesting illustration of the impact 3-D seismic interpretation can have on the understanding of a field’s geology. The evolution of our understanding of Cougar’s structure, and the impact of seismic interpretation techniques on that understanding are reviewed here.
