The well will be properly plugged and abandoned by setting cement plugs to isolate the Niobrara formation, freshwater zones, and setting a cement cap near the surface. Then the surface casing will have a plate welled as final seal 5' below the surface. The old wellbore will then be buried and the surface location will be remediated. 400595352 400595352 FORM 6 INTENT SUBMITTED 400595352.pdf 400595352 400595390 WELLBORE DIAGRAM Duell #4B-1_Current WBD.pdf 11571 400595352 400595391 WELLBORE DIAGRAM Duell #4B-1_Proposed WBD.pdf 11647 400595352 400595392 PROPOSED PLUGGING PROCEDURE Duell #4B-1_Proposed Plugging Procedure.pdf 90761 400595352 400595393 LOCATION PHOTO Duell 4 B1_Well Site Photos.pdf 442292 400595352 400595394 SURFACE AGRMT/SURETY Duell 4 B1_Surface Use Agreement.pdf 60236 400595352 DSND 6808 400595352 JSND 6887 400595352 NBRR 6075 CEMENT 400595352 0 false 400595352 1 false 400595352 2 OPEN HOLE 86 3600 3900 false 400595352 3 CASING 177 0 600 false 400595352 4 false 400595352 5 false 400595352 6 false 400595352 7 false 400595352 8 false 400595352 9 false 400595352 10 false 400595352 11 false 400595352 12 false 400595352 13 false 400595352 14 false 400595352 15 false 400595352 16 false 400595352 1ST 7 1 8 5 1 2 15.5 6994 100 6994 5955 CALC ACTUAL 400595352 SURF 12 1 4 8 5 8 24 411 280 411 0 CALC ACTUAL Thread was being aborted.
