Wellbore system with dissolving ball and independent plug latching profiles
A wellbore system includes a first plug and a second plug that latch independently within an elongated housing; at least one plug having an elongated channel with a ball therein for performing operation of a pressure test; and optionally including a ball seat for receiving a dissolving ball for contingency and supplementary casing tests.
1. A wellbore system, comprising:
an elongated housing extending from a first end to a second end;
a first plug seat positioned within the elongated housing;
a first plug configured to engage with the first plug seat, the first plug having:
an elongated body forming a channel extending from a top end to a bottom end,
the channel has a first width; and
a nose positioned at the bottom end of the channel and forming a second width,
the second width being less than the first width;
a ball carried and sealed within the channel between the top end and the bottom end of the elongated body of the first plug such that the ball is configured to be launched with the first plug from a surface and is protected from fluid flow, the ball having a circumference, wherein the circumference is less than the first width and greater than the second width;
wherein the ball is configured to travel through the channel of the first plug and rests within proximity to the nose.
2. The system of claim 1 , further comprising:
a dissolvable ball configured to be pumped into the elongated housing to rest within a ball seat of the elongated housing.
3. The system of claim 1 , further comprising:
a second plug seat; and
a second plug configured to engage with the second plug seat.
4. A wellbore system, comprising:
an elongated housing extending from a first end to a second end and having a guide nose engaged with the second end;
a first plug seat having a first latch;
a first plug having a first elongated body and a first nose positioned at an end of the elongated body, the first nose having protrusions configured to engage with the first latch, the first plug having a ball sealed within an elongated channel of the first plug such that the ball is configured to be launched with the first plug from a surface and is protected from fluid flow;
a second plug seat having a second latch; and
a second plug having a second elongated body and a second nose positioned at an end of the second elongated body, the second nose having protrusions configured to engage with the second latch;
wherein the first plug and the second plug latch independently within the elongated housing.
