Cementing Wiper Plugs and Darts Weatherford International
Our plug and dart systems—including casing, multistage, multiple latchin highpressure rupture, and subsurface release plugs—separate displacement fluid, effectively wipe tubulars, and reduce cement contamination during cementing operations in virtually all well conditionsThe Drill Pipe Wiper Plug (CTDPWP) is released behind the cement When it reaches the CTCLWP, the CTDPWP latches and seals into it Differential pressure across the CTCLWP launches it The Casing/liner wiper plug is displaced through the liner, acting as a mechanical barrier behind the cementCasing Wiper Plug COMPLETION OIL TOOLSwiper plug 1 n [Drilling] Another term for cementing plug, a rubber plug used to separate the cement slurry from other fluids, reducing contamination and maintaining predictable slurry performance Two types of cementing plug are typically used on a cementing operation The bottom plug is launched ahead of the cement slurry to minimize contamination by fluids inside wiper plug Oilfield Glossary Schlumberger
