Results of Loeeina <br />Attached please find gamma ray/CCL log; 8 '/2 by 11" copy of baseline (11-7-03) <br />compared to current collar locator log, and temperature log. Interpretation of logs <br />was by Mr. Rod Storey, NSI drilling supervisor. In summary, the gamma ray log <br />indicates all collazs to 1760' are intact with no detectable movement. <br />The 9-15-04 temperahu'e log indicates a normal temperature gradient with changes <br />noted at 500' for water level, 1250' for A-Groove and 1600-1650' for B-Groove. <br />Similar to temperature log from 5-6-04, there is no indication of water movement <br />down the annulus as noted in prior logs, i.e. 1-13-04. The big change from previous <br />log (1-13-04) and prior to final cementation was a cool down at 1750' from 173 <br />degrees F to 145 degrees F (9-15-04). Also, at 1770' a decrease from 185 to 148.6 <br />degrees F was noted. NSI believes the declining temperature is a result of cement <br />job in Apri12004 and pull back of injection point in 6H. In summary. eamma log <br />indicates no detectable subsidence to 1760'. and temperature log indicates <br />additional evidence that annulus was successfully cemented; and elevated <br />temperatures are declining as expected following cement lob and pull back. NSI <br />will bail-out the bottom of 3M-TDR to obtain additional length for logging. <br />Subsidence cables #2 and 3 for 3M-TDR continue to be monitored for subsidence <br />data. Data from #3 is of limited value and logging will be performed at least <br />annually to provide subsidence data. <br />If there are any questions please contact Mr. Rod Storey or me. <br />Sincerely, <br />~- <br />Ed Baker, REM <br />EHS Manager <br />CC: BLM <br />:EPA <br />
