  • Publication number: 20200032610
    Abstract: An apparatus, system and method are provided for isolating a portion of a tubing string in a hydrocarbon well. The portion of isolated tubing string can be used to set a packer or test tubing integrity hydrostatically. The apparatus includes a dissolvable valve that is installed in a nipple and positioned below the portion of tubing string. The dissolvable valve includes a ball seat for receiving a dissolvable ball. When the dissolvable ball is dropped into the tubing string and seated on the ball seat of the dissolvable valve, the portion of tubing string is isolated from a second portion of tubing string below the nipple. Wellbore fluids in the hydrocarbon well dissolve the dissolvable valve and the dissolvable ball to leave behind a nipple without any restrictions.
