readings to be definitively equated to hydraulic isolation. Attachments 12 - 17 contain the Halliburton Detailed ACE interpretations. These reports summarize the tool responses and isolation for various depth intervals in the TM -1, TM -2, TM -3, TM -4, TM- 5 and TM -6. Attachments 18 — 21 contain the Schlumberger IBC logs for the TM -2, TM -3, TM -5 and TM -6. In the shallow portion of the TM -2 well (the same interval that the CBL -VDL tool indicates BI readings above 60% but not free pipe) the Detailed ACE report shows intervals of "Fair" and "Good" that can now be equated to hydraulic isolation because of the retort isolation test. Isolation is indicated from 314 ft. to 362 ft., 362 ft. to 400 ft., 400 ft. to 422 ft., 422 ft. to 820 ft. and 820 ft. to 903 ft. The Schlumberger IBC log presentation includes a hydraulic isolation map shown in the right hand track. When the IBC identifies six feet of continuous connected liquid, the map displays blue and this indicates no hydraulic isolation. Conversely, when hydraulic isolation is indicated, the map displays white'. The TM -2 Schlumberger IBC hydraulic communication map in Attachment 18 also indicates numerous intervals that are hydraulically isolated between 400 ft. and 740 ft. In the shallow portion of the TM -3 well, the Halliburton Detailed ACE report shows "Fair" and "Good" readings from 100 ft. to 114 ft., 280 ft. to 300 ft., 404 ft. to 420 ft., 448 ft. to 536 ft. and 570 ft. to TD that can be equated to hydraulic isolation. The Schlumberger IBC log predicts isolation at the following intervals 271 ft. to 277 ft., 613 ft. to 619 ft., 685 ft to 739 ft., 770 ft. to 805 ft., 811 ft. to 864 ft. and 870 ft. to 900 ft. The CAST /ACE and IBC log results also provide confirmation of the calibrated BI calculations and predicted hydraulic isolation for other intervals in the TM -2 and TM -3, and the readings in the TM -5 and TM -6 wells. Based on my review of the Halliburton CAST /ACE information and the Schlumberger IBC logs along with the recently conducted retort isolation test, hydraulic isolation can be demonstrated in TM -2 and TM -3 for the Uinta HU. TM -1 and TM -4 wells Due to the permanent setting of tubing and instruments in casing it is not possible to run additional evaluation logs in either the TM -1 or the TM -4 well. The only cement evaluation log on the TM -1 well is the Halliburton CAST -F log that was run on July 7, 2011. The only cement evaluation log on the TM -4 well is the Halliburton CAST -M log run on April 11, 2011. The TM -2 retort isolation test also allows these CAST /ACE determinations to be equated to hydraulic isolation. One cautionary note: when white is displayed and the Solid- Liquid -Gas map displays red indicating Gas, the white Hydraulic Communication map is not indicative of isolation, but of dry micro - annulus.
