The 7” casing became stuck at 7530’ MD. We cemented the shoe with 500’ of cement in the annulus. Then we came up to 6660’ and perforated the casing. We cemented the casing through the perforations. The cement is from 6660’ to 540’. We then attempted to go back to drilling. We cut 150’ of new hole in the Niobrara. The drill pipe became stuck and hole conditions have continued to deteriorate. 400280421 400280421 FORM 6 SUBMITTED 400280421.pdf 400280421 400280918 WELLBORE DIAGRAM Schomber 13N-22HZ PA Schematic.pdf 197249 400280421 0 40 7530 false 400280421 1 false 400280421 2 CASING 40 6560 6760 false 400280421 3 false 400280421 4 false 400280421 5 false 400280421 6 false 400280421 7 false 400280421 8 false 400280421 9 false 400280421 10 30 865 995 false 400280421 11 10 false 400280421 12 false 400280421 13 false 400280421 14 false 400280421 15 false 400280421 16 false 400280421 S.C. 1.1 8 3 4 7 26 7530 122 7530 6658 CALC ACTUAL 400280421 S.C. 2.1 8 3 4 7 26 6560 503 6560 541 CALC ACTUAL 400280421 SURF 13 1 2 9 5 8 36 936 690 936 16 CALC ACTUAL Thread was being aborted.
