Abstract
The present casing wiper plug system and method includes a novel top wiper plug and a dissolvable blocking element. The top wiper plug includes a rupture disk and an open tail section configured and dimensioned to receive the dissolvable blocking element. The blocking element can be dissolved by a solvent and can dissolve quickly given the size or materials of the blocking element. When used in conjunction with a bottom wiper plug and a displacement fluid, the central bores of the top and bottom wiper plugs and shoe track provide an open passage to the formation allowing future injection or fracking fluid to access the formation. The blocking element is released into a seat of the open tail section to temporarily block the passage so a casing test can be performed on the casing. After the test is complete, the blocking element is dissolved to reopen the passage.
