  • Publication number: 20150285024
    Abstract: A bridge plug with a selectively blocked flow passage is delivered on wireline and pumped down to the desired location and set. A casing pressure test can be performed above the bridge plug while shielding the formation below from excess pressure from the pressure test. To the extent there are producing zones below the bridge plug or adjacent injection wells that could communicate with the borehole, the plug isolates those pressures from below. After the pressure test is completed, a rupture disc is blown in a passage through the bridge plug and flow is then used to deliver completion equipment to a horizontal portion of the borehole and preferably on wireline.
