~_ <br />Evaluation of cement -American Soda #20-33 <br />CBL and CAST tools were run in the above listed well to evaluate [he placement and quality of the cement slurry. CBUCAST 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 [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 this well indicate the following: <br />Depth Interval Description Isolation <br />Evaluation CAST <br />Impedance Value CAST <br />Impedance Character CBL Pipe Amplitude MSG pipe signal <br />TD [0 1,923' Free Pipe (long string) No isolation I.5 Flat consistent 63, Free pipe value strong <br />1,923' Cement Basket N/A N/A N/A N/A N/A <br />1,923' to 1,914' Bentonite Plug Good 2+ Medium activity <free pipe value Faded Slightly <br />1,914' to 1,882' Mixture of Spherlite and conventional cmt Good 2 -4+ Med.
