P-wave seismic time-lapse analysis of horizontal well completions causing pressure compartmentalization
MetadataShow full item record
When horizontal wells are completed many changes can occur. During completions, pressure changes take place because of the fluid and proppant injected. One way of monitoring such changes is through the use of time-lapse seismic data. In Wattenberg Field, located near Greeley, Colorado, Anadarko Petroleum Corporation (APC) has teamed up with the Colorado School of Mines Reservoir Characterization Project (RCP) to acquire time-lapse seismic data over a section of land in which eleven horizontal wells were completed. The P-wave seismic is of considerable interest since the P-waves are sensitive ...
