Time-lapse PP seismic to characterize stimulation and production behavior in the Niobrara and Codell reservoirs Wattenberg field, Colorado, US
MetadataShow full item record
The primary source of present-day, on-shore oil and natural gas production in the United States is within unconventional, tight reservoirs. Recovery factors in unconventional reservoirs are typically 5-15\%, and substantially less than in conventional reservoirs. Current hydraulic fracturing and completion efforts are directed to improving recovery, where even a 1\% increase could substantially impact the economics of the field. The Wattenberg Field is among the most successful unconventional fields in the United States, targeting the Niobrara and Codell formations. The Reservoir Characterization ...
