., <br />~~ - <br />Evaluation of cement -American Soda #20-31 <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 1,860' Free Pipe (long string) No isolation I.5 Flat consistent 61, Free pipe value strong <br />1,860' Cement Basket N/A N/A N/A N/A N/A <br />1,860' to 1,852' Bentonite Plug Good 2 Medium activity < free pipe value Faded Slightly <br />1,852' [0 1,830' Conventional cement Good 2 - 4 Medium activity Low, < 10 to < 30 Faded to none <br />1,830' to 1,818' Partial cement and Gee Fluid Poor 2 Medium activity 30 to 40 Shong <br />1,818' to 1,756' Good conventional cement Good 3 - 5 Medium activity Low, < 10 None <br />1,756' to 1,561' Mixture o(Spherlite and conventional cmt Good I - 5 Med.
