The results of a systematic test program to evaluate float equipment performance are presented. The testing has destroyed, over an eightmonth period, 160 float valves, float shoes and float collars. A new float valve design with greater resistance to failure has been developed as a result of the testing. New float collars and float shoes are expected to provide the operator with a failure rate of less than 1 1/2% when used within design limits and under normal cementing conditions. Further testing objectives include: extension of operating temperature limits to include deep well and geothermal conditions, and evaluation of the effects of more abrasive mud and cement systems.
