s <br />Evaluation of cement -American Soda #20-12 <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, from the base <br />of each string to surface or to [he fluid level in [he casing string. A cement basket is positioned near [he bottom of the shorter string and cement is placed in the annulus from <br />the cement basket to near surface. <br />The logs on [his 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 to 1,624' Free Pipe (lon¢ string) No isolation 1.4 Flat consistent 68, Free pipe value strong <br />1,624' Cement Basket N/A N/A N/A N/A N/A <br />1,624' [0 1,620' Bentonite Plug Good 2+ Medium activtry < free pipe value Faded Slightly <br />1,620' [0 1,606' Mixture of Spherlite and conventional cmt Good 2 - 4+ Med.
