5th Formation Evaluation
Symposium of the Canadian Well Logging Society in Calgary, May 5-7,



A field test of one company’s various Cement Bond Log tools was run to evaluate the effect of varying signal frequencies and tool diameters. Two larger diameter sondes with different frequencies were run and results are presented. One higher frequency, smaller diameter tool was run and results are compared with the other logs. Problems that occurred during the test (and that also occur in the field) included the microannulus effect, centering and gating difficulties.
