Evaluation of cement -American Soda #20-36 <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 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 to 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 to 2,007' Free Pipe (long string) No isolation 1.7 Flat consistent 62, Free pipe value strong <br />2,007' Cement Basket N/A N/A N/A N/A N/A <br />2,007' [0 1,988' Conventional cement Good 2 - 4+ Med.
