Patent number: 11788403Abstract: The detection of a barrier behind a wellbore casing involves the injection of a fluid into the wellbore casing or the pumping of a fluid from the wellbore casing, and the monitoring in real-time of the fluid properties in two downhole fluid volumes separated by a packer. A detection system utilizes a pipe string equipped with a telemetry that is capable of transmitting fluid property data to a surface monitor while the pipe string remains in the wellbore casing, and preferably while the packer remains set against the wellbore casing.Type: GrantFiled: August 12, 2020Date of Patent: October 17, 2023Inventors: Andrew Hawthorn, Knut Inge Dahlberg
