We worked the pipe to 20' and were able to pump 1.5 bbls of cement to top off the well. 2.5 more bbls of cement were mixed for this job and circulated to the pit. COGCC's eform database would not accept duplicate formations under "Current and Previously Abandoned Zones". This Form 6 indicates that along with the CIBP set at 1500', cement plug also set at 1325' and a RBP at 2424'. 400482705 400482705 FORM 6 SUBSEQUENT SUBMITTED 400482705.pdf 400482705 400482733 CEMENT JOB SUMMARY 8-13-2013 Cement Report for P&A - Scott 21-4.pdf 46550 400482705 400482734 CEMENT JOB SUMMARY 8-27-13 Cement Report 2 for P&A - Scott 21-4.pdf 49193 400482705 400482762 WELLBORE DIAGRAM Wellbore Diagram for P&A - Scott 21-4.pdf 102302 400482705 400485431 WIRELINE JOB SUMMARY 11-11-2009 Job Ticket for CIBP at 1500' - Scott 21-4.pdf 210286 400482705 RTON 1550 2842 2013-08-13T00:00:00-06:00 B PLUG CEMENT TOP 1500 400482705 0 false 400482705 1 false 400482705 2 false 400482705 3 false 400482705 4 false 400482705 5 false 400482705 6 false 400482705 7 false 400482705 8 false 400482705 9 false 400482705 10 89 500 0 false 400482705 11 false 400482705 12 false 400482705 13 false 400482705 14 false 400482705 15 false 400482705 16 false 400482705 1ST 7 7 8 5 1 2 17 3061 690 3061 0 CBL ACTUAL 400482705 SURF 11 8 5 8 24 420 463 420 0 CALC ACTUAL Thread was being aborted.
