Injected Iodine <br />13,1 radioactive tracer into well annulus. Flushed with raw water <br />from plant tank hauled to location by Dalbo water truck. <br />Followed trace through all aquifers and to below perforations in <br />casing. Lost track of trace after 1660 feet, as trace moved away <br />from casing wall. Logged to bottom and out trying to find trace. <br />No success.

One Dalbo truck had 30 BBL sodium <br />silicate loaded. <br />Pump 30 BBL water down 4 -1/2 casing to establish rate and <br />pressure. <br />Pumped 30 BBL @ 2BBL /min. 0 PSI. <br />Start cement down annulus. Pump @ 3 bbl /min. 0 PSI. <br />Pump 10 bbl sodium silicate down 4 -1/2 casing. 0 PSI. <br />When 61 BBL cement volume was pumped down annulus, started <br />pumping sodium silicate down 4 -1/2 casing @ 1 bbl / min. <br />Report 4 #1 <br />
