A dissolvable frac plug with an internal chamber surrounded by an external wall with the chamber containing a tracer compound in an amount sufficient to be observed from water or other wellbore fluids when released. The tracer compound is released from the chamber as a portion or portions of the external wall dissolves due to contact with water or other wellbore fluids. The released tracer compound can be monitored from the water or other wellbore fluids.

Dissolvable frac plug housing tracer

A dissolvable frac plug is disclosed. The dissolvable frac plug has an internal chamber surrounded by an external wall with the chamber containing a dry powder component in an amount sufficient to combine with ground water or other wellbore fluids to form a solution or environment that enhances dissolution of the plug. The dry powder is released from the chamber as a portion or portions of the external wall dissolves due to contact with water or other wellbore fluids.

Dissolvable frac plug

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.

Casing wiper plug system and method for operating the same

A wiper plug that includes an elongated body member having a forward end, a rearward end, and an open central bore; spaced radially outwardly projecting wiping flanges made of flexible material and configured to extend beyond the inner diameter of the pipe to be cleaned but that deform to apply contact wiping pressure to the inner diameter of the pipe as the wiper plug travels through the pipe; and shearing elements that extend from the rearward end of the elongated body member by a distance that is greater than the inner diameter of the pipe to be cleaned. The shearing elements hold the wiper plug in position in between two connected pipe sections while the open central bore allows cement to flow therethrough. Also, a carrier pipe for the wiper plug and method of use thereof for cleaning cement from the wellbore annulus of long casing strings.
