  • Methods and systems for frac plugs with pump down rings
    Patent number: 11085267
    Abstract: A Frac plug with multiple pump down rings, wherein the outer diameter of the pump down rings is smaller than that of the inner diameter of the casing, which may not allow a seal to be formed across the casing. Systems may also include a rupture disc within the Frac plug that is positioned adjacent to an atmospheric chamber, which allows the rupture disc to be removed based on a known pressure.

  • METHODS AND SYSTEMS FOR A FRAC PLUG
    Publication number: 20210032956
    Abstract: An outer diameter of a mandrel with a recess to accommodate lower slips with a larger thickness, a sealing element with a concave outer diameter to control a pressure differential caused by a Bernoulli Effect across the sealing element, and a disc that is selectively secured to a housing via a removable shear pin, wherein shear pins with different pressure ratings may be inserted into the housing.
