:~ <br />Evaluation of cement -American Soda #20-30 <br />CBL and CAST tools were run in the above listed well to evaluate the placement and quality of the cement slurry. CBL/CAST logs were run in both casings, front the base <br />of each string to surface or to the fluid level in the casing string. A cement basket is positioned near the bottom of the shorter string and cement is placed in the annulus from <br />the cement basket [o near surface. <br />The logs on this well indicate the following: <br />Depth Interval Description Isolation <br />Evaluation CAST <br />Impedance Value CAST <br />Impedance Character CBL Pipe Amplitude MSC pipe signal <br />TD [0 1,884' Free Pipe (long string) No isolation 1.7 Flat consistent 65, Free pipe value strong <br />1,884' Cement Basket N/A N/A N/A N/A N/A <br />1,884' fo 1,876' Bentonite Plug Good 2+ Medmm activity <free pipe value Faded Slightly <br />1,876' [0 1,800' Conventional cement Good 3 - 5+ Med.
