... perpendicularly out of a closed-ended pipe, does not have any function. The placement of a balanced plug is feasible. However, a high-density fluid above a lighter fluid is not stable. The phenomenon is known as Rayleigh-Taylor instability. In principle, to be reasonably stable, the interface must be horizontal...

...Anisa Noor Corina; Nils Opedal; Torbjørn Vrålstad; Ragnhild Skorpa; Sigbjørn Sangesland Summary In permanently abandoned wells, cement plugs serve as a well‐barrier element that is essential for providing long‐term zonal isolation. Poorly plugged wells might provide leakage pathways that pose risks...

Continuing the research effort, this paper discusses another approach for designing LCMs to withstand higher wellbore pressures within a fracture. A property of plug-breaking pressure (PBP) was determined for different LCM...
