  • Method for isolation of borehole pressure while performing a borehole operation in a pressure isolated borehole zone
    Patent number: 11851960
    Abstract: An adaptive seat is run in with an isolating object to beyond a landing location for the adaptive seat. The adaptive seat is released to expand and engage the surrounding tubular. Pressure from below acts on the object and propels the object against the adaptive seat. The object and the adaptive seat move in the tubular to a nearby landing location such as a groove or recess in a sub that is part of the string or another location such as a tubular joint where the adaptive seat finds support. An upper portion of the borehole is isolated for a time from formation pressure to allow running in an ESP from the surface. The object is removed by degradation or from being structurally undermined and the ESP is operated to produce the formation. One or more removable barriers are contemplated.
