Title: SYSTEMS AND METHODS FOR SEALING A WELLBORE
Abstract:
Systems and methods for sealing a wellbore are described. The system includes a packing element configured to at least partially seal an uphole portion of a wellbore from a downhole portion of the wellbore. A first annular pressure sensor is positioned uphole of the packing element. The first annular pressure sensor is configured to measure a first pressure within the wellbore uphole of the packing element. A second annular pressure sensor is positioned downhole of the packing element. The second annular pressure sensor is configured to measure a second pressure within the wellbore downhole of the packing element. A control sub-assembly is configured to be positioned within the wellbore. The control sub-assembly is configured to monitor a sealing efficiency of the system by comparing the first pressure and the second pressure.
