Niobrara Fracture Prospecting Through Integrated Structural and Azimuthal Seismic Interpretation, Silo Field Area, Wyoming

3-D Seismic Characterization of the Niobrara Formation, Silo Field, Laramie County, Wyoming

“…Faults and fractures are important features in Silo Field as they control the production (Sonnenberg, 2011a). The low porosities and permeabilities of the Niobrara are enhanced by the presence of faults and fractures (Treadgold et al, 2012). The origin of these features is not well-understood and several ideas for fracture genesis have been proposed.…”

“…It is tight and has porosities ranging from 8-10% and low permeabilities between <0.01 and 20 milidarcies (Vincelette and Foster, 1992, Luneau, 2011, Sonnenberg, 2011a, Sonnenberg, 2011b, Malesardi, 2012, and Treadgold et al, 2012. The chalk beds are the main reservoirs, sourced by adjacent marls Weimer, 1992 andLandon et al, 2001).…”

“…Several authors have published their work on various aspects of Silo Field including: Svoboda (1995), Malesardi (2012), and Treadgold et al (2012).…”

“…Figure 1.4 shows the thickness of the Niobrara in the WICS, which ranges from as little as 100 feet in South Dakota to as much as 1800 feet in Wyoming (Longman et al, 1998). In Silo Field, the thickness is approximately 300 feet (Figure 1.5) and lies between 7100 and 8800 feet depth (Longman et al, 1998, Luneau et al, 2011, Sonnenberg, 2011a, and Treadgold et al, 2012. Hays Limestone (Sonnenberg and Weimer, 1992).…”
