Positive Sealing Plug
Positive Sealing Plugs are used in Rigless zonal isolations and recompletions and set in casing diameters up to 3 1/2 times their run-in diameter.
Like Cast iron bridge plugs PSP's have robust anchor systems and elastomeric seals that provide immediate pressure isolation upon setting in casing. Cement is placed atop the plug to assure long-term zonal isolation.
PSP's are run on wireline, slickline, tractor, coiled tubing, and threaded pipe and can be set in open hole, cased hole, perforated casing intervals, and gravel packs.
PSP's and their supporting setting tools can be run to 20,000 psig (1,361 bar) and 400o Farenheit
* 2-1/8" PEP Plugs have a run in I.D. of 2.125" and can set in casing as big as 9-5/8"
* 1.75" PEP Plugs have a run in I.D. of 1.75" and can set in casing as big as 7"
