... realized from the use of buoyant ball sealers. Positive-displacement ball injectors effect reliable introduction of buoyant balls into the treating fluid, and ball catchers have been designed and used to recover the balls following the treatment. In lieu of ball retrieval, the controlled-density ball...

... of the IBOP plug and the use of mechanical separation. This can be achieved in multiple ways that encompass the use of a ball/dart catcher set deeper in the well and a mechanism for preventing flowback when pulling out of the plug, as described in the next section. With this technique, cementing plugs of up...

... the tool. The time involved in the operation may be eliminated by predropping the ball onto a pre-installed ball catcher. In this position normal flow is allowed to pass, however, increasing the pumprate beyond a certain level will shear a bolt and allow the ball to drop onto the ball seat. After setting...

.... The job was completed in 5 hours. Another well with 16 stages was to be treated using low-temperature foam at 50°C (122°F). Following treatment, five partially degraded frac balls were caught in the ball catcher 53 hours after comple- tion of the 16th stage. After 72 hours, the ball catcher was rechecked...
