The well will be properly plugged and abandoned by setting cement plugs to isolate the Niobrara, 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. 400590476 400590476 FORM 6 INTENT SUBMITTED 400590476.pdf 400590476 400590489 WELLBORE DIAGRAM Huston 1_Current WBD.pdf 11685 400590476 400590491 PROPOSED PLUGGING PROCEDURE Huston 1_P&A Procedures.pdf 91452 400590476 400590492 WELLBORE DIAGRAM Huston 1_Proposed WBD.pdf 11777 400590476 400590494 OTHER Huston 1_Surface Use Agreement.pdf 513572 400590476 400590495 OTHER Huston 1_Well Site Photos.pdf 513496 400590476 DSND 6798 400590476 JSND 6884 400590476 NBRR 6058 CEMENT 400590476 0 false 400590476 1 false 400590476 2 CASING 135 4200 4500 false 400590476 3 CASING 271 0 600 false 400590476 4 false 400590476 5 false 400590476 6 false 400590476 7 false 400590476 8 false 400590476 9 false 400590476 10 false 400590476 11 false 400590476 12 false 400590476 13 false 400590476 14 false 400590476 15 false 400590476 16 false 400590476 1ST 7 1 8 5 1 2 15.5 6933 200 6933 6278 CALC ACTUAL 400590476 SURF 12 1 4 10 3 4 32.8 103 75 103 0 CALC ACTUAL Thread was being aborted.
