Using the values from the example above, your chart will <br />look like that shown below: <br />,oo <br />00 <br />,o <br />ao ~ <br />:o <br />w ~ ~ <br />ro ' <br />0% BOND ' <br />,p 81 mV <br />' 100% BOND <br />+ ' <br />5 ~ 1mV ' <br />~ , <br />Q , ~ <br />I I ~ <br />a 2.4 mV ~ <br />e <br />Q + <br />6 <br />S <br />0 <br />80% BOND <br />o +v m as w eo ev ~o eo vv +vv <br />BOND <br />In this example, 80% bond shows an amplitude of 2.4 mV. <br />A convenient way to evaluate the log is to draw a line on <br />the bond log's amplified amplitude (SX) track corresponding <br />to the calculated 80% bond amplitude. Whenever the logged <br />amplified amplitude (SX) curve drops below (to the left of) <br />the drawn line, this indicates a bond of 80% or more. <br />PART IV - CONCLUSIONS - REMINDERS <br />Different pipe weights and cement types will affect the log <br />readings, so be mindful of these factors in wells with <br />varying pipe weights and staged cement or squeeze jobs. <br />Prlnfed on Recycled Paper <br />
