Attached is a plot for the MRP #2. The plot does notp phave the recent well production after upgrading GLinstallation. However, the last test was 142 BOPD,500 BWPD, 20 MCFD, 64/64 choke, 210 FTP, 1170psi csg, 556 injection. I will send a chart next week with theupdated productionupdated production.
