0 <br />TM -1 <br />The Halliburton Detailed ACE evaluation of the TM -1 CAST log reports "Good" <br />bond and "Good zonal isolation" from TD -1888 ft., 1831 ft. to 1764 ft., 1256 ft. <br />to 1215 ft. and 432 ft. to 400 ft. Other zones with a "Good" rating include 1888 <br />ft. to 1833 ft., 1764 ft. to 1256 ft. and 1215 ft. to 432 ft. Since the "fair" rated <br />zone tested by the TM -2 retort isolation test provided' hydraulic isolation, these <br />"Good" rated zones provide assurance of hydraulic isolation for the required <br />intervals. <br />TM - 4 <br />The Detailed Halliburton ACE evaluation of the TM -4 CAST log from TD to <br />1648 reported "Good" bond and from 86 ft. to 108 ft., 600 ft. to 625 ft., 700 ft. to <br />1040 ft and 1040 ft. to 1648 ft. reported "fair ". Since the TM -2 retort isolation <br />test provided hydraulic isolation in a zone with a CAST /ACE rating of "fair ", the <br />"good" and "fair" ratings in the TM -4 provide assurance of hydraulic isolation for <br />the required intervals. <br />WELLBORE TEMPERATURE INFORMATION <br />I have also been provided with temperature data from the T 1 -P, the TM -1 and the TM -4 <br />wells. These wells are equipped with fiber optic temperature sensors that allow <br />continuous temperature measurements along the wellbore. My review of this data did not <br />uncover any temperature anomalies. In addition, wireline temperature logs have been run <br />on the TM -2, TM -3, TM -5 and TM -6 to serve as baseline measurements prior to heating <br />operations. It is my understanding that wells TM -2, TM -3, TM -5 and TM -6 will also be <br />equipped with temperature instrumentation. <br />During the down -hole heating operations, the temperature instrumentation will provide a <br />way to monitor each well for unusual temperature responses. If these responses are <br />interpreted as mechanical integrity issues, the heating process can be stopped, pressure <br />bled off and remedial action taken. The ability to monitor temperature in the wellbores <br />provides additional assurance of zonal isolation. <br />CONCLUSIONS <br />Based upon the above discussed analysis, I have concluded that for wells TM -1, TM -2, <br />TM -3, TM -4, TM -5 and TM -6, hydraulic isolation is demonstrated for the following <br />required intervals: <br />1. Between the Rl zone and the Dissolution Surface <br />2. Between the L3 HU the `B" Groove L6 <br />3. Between the "A" Groove L7 and Uinta HU <br />
