Abstract
A wellbore seal includes a eutectic plug and a gauge assembly. The eutectic plug is configured to sealably engage a casing or a formation. The gauge assembly is connected to a lower side of the eutectic plug. The gauge assembly includes a pressure gauge configured to measure a pressure of a fluid, and an acoustic transceiver in communication with the pressure gauge and configured to transmit an acoustic signal based on the pressure through the eutectic plug.
Claims15
A wellbore seal comprising:
- a eutectic plug configured to sealably engage a casing;
- a first gauge assembly connected to a lower side of the eutectic plug, the first gauge assembly including,
- a pressure gauge configured to measure a pressure of a fluid, and
- an acoustic transceiver in communication with the pressure gauge and configured to transmit an acoustic signal based on the pressure through the eutectic plug;
- and
- a second gauge assembly positioned at an upper side of the eutectic plug, wherein the first gauge assembly and the second gauge assembly are acoustically and communicatively coupled with one another through the eutectic plug.
