A large multi-client, full-azimuth 3D seismic survey of almost 800 square miles in southeastern Wyoming is the basis for a regional structural interpretation and azimuthal velocity analysis of the Niobrara in the area of the Silo Field, in the northern end of the Denver-Jules Basin. The unconventional Niobrara oil and gas play has been compared to the Bakken in North Dakota but variable well results have long plagued operators. Silo Field has produced about 10 million barrels of oil since 1981 but well rates can vary drastically over a short distance. The study integrates seismically derived rock attributes, well and production data, and integrated regional structural interpretation to understand the Niobrara fracturing and to reduce drilling risk.
