Technology For HTHP well, a pump out plug is installed at end of tubing. Once packer is set, a higher pressure will apply to ball seat and shear cut the pins. Ball and ball seat will drop into bottom hole. Often those debris will be carried out of well to stuck wellhead or surface manifold. To solve this, EverGreen designed a dissolvable seat pump out plug which can dissolve in 1-3 months after it is sheared cut to bottom hole. |
