Niobrara top is 7044 ft MD which requires a CBL to be run to 6844 ft MD per the COA on the APD to satisfy Rule 317 i. Liner top is 6634 ft MD. A CBL was run to a depth of 6720 ft MD, which is 124 ft short of the depth required by the COA. This shortage was an oversight on GWOG’s part and we now are ensuring CBLs are run to the required depth. Even though we were 124 ft short we still believe we have adequate isolation at 200 ft above the Niobrara because of the very good cement bond shown on the CBL (dated 9/4/2014). No spacers of any kind were pumped in the middle of the cement job and there was no overdisplacement so there is no reason to believe the same very good bond signature is not 200 ft above the top of Niobrara. See attached cement event log as evidence no spacers occurred during the cement slurry. 400970620 400970620 FORM 5 SUBMITTED 400970620.pdf 400970620 400971155 PDF-RESISTIVITY L Pastle IC 11-342 HC_RESISTIVITY.pdf 7493674 400970620 400971157 PDF-CEMENT BOND L Postle IC11-342HC CBL.pdf 2840483 400970620 400971159 LAS-MEASUREMENT/LOGGING WHILE DRILLING L Postle ic 11-342hc.LAS 1797935 400970620 400971168 LAS-MEASUREMENT/LOGGING WHILE DRILLING L Memory_Postle_IC_11-342HC_LAS.las 1727201 400970620 400971173 PDF-MEASUREMENT/LOGGING WHILE DRILLING L Memory_Postle_IC_11-342HC_5md_GR.pdf 560085 400970620 400971333 DIRECTIONAL DATA COGCC Directional Postle IC 11-342HC Final.xlsm 38607 400970620 400971343 DIRECTIONAL SURVEY Postle IC 11-342HC - COGCC Final Survey.pdf 117242 400970620 400972264 CEMENT JOB SUMMARY Postle IC 11-342HC - Cmt Job Summary.pdf 786575 400970620 1ST 8 3 4 7 26 7586 735 7586 116 0 CBL ACTUAL 400970620 1ST LINER 6 5 8 4 1 2 11.6 11913 335 11913 6634 6634 CALC ACTUAL 400970620 CONDUCTOR 24 16 42 40 61 40 0 0 VISU ACTUAL 400970620 SURF 13 1 2 9 5 8 36 1043 460 1043 0 0 VISU ACTUAL 400970620 cement work 400970620 cement work Thread was being aborted.
