Bell Creek Test Site - First Full Repeat of Pulsed Neutron Logging Campaign Completed
Monitoring, verification, and accounting (MVA) techniques such as the full repeat of pulsed-neutron logs (PNLs) have helped to guide a repeat vertical seismic profile by monitoring CO2 breakthrough between production and injection wells to improve overall MVA efforts and understanding of sweep efficiency, effective storage capacity, and vertical and lateral flow boundaries. This PNL logging campaign comprised two steps: first running a baseline set of logs and second running a repeat set of logs to compare against the baseline. The baseline logs were completed on 33 wells from November 2012 to June 2013. Repeat logs were completed on seven wells from August 2013 to January 2014.View/Download Document
