6'-Drill-Pipe-Wiper-Balls-Merit
The customer was spending up to three extra hours on trips out of the hole to wipe out cement. They wanted to wipe a drill-pipe smooth after performing a shoe squeeze through 5-in. drill pipe with an 8-1/2-in. bit with three 20/64th nozzles installed. The squeeze was done at 9,200 (2804 m) TVD/MD with a bottom hole circulating temperature (BHCT) of 165°F. A 7-in. foam wiper ball was recommended because it can pass through a 1-in. restriction. The 7-in. foam wiper ball wiped out the drillpipe successfully and passed through the bit with little increase in pump pressure. The customer was very pleased with the wiping action and versatility of Merit’s foam wiper balls.
