1. A method, comprising:
receiving a real-time annulus pressure of an annulus defined between a production tubing and an inner wall of a wellbore;
comparing the real-time annulus pressure to a predetermined target pressure for the annulus;
sending a command signal to a pressure regulator valve in fluid communication with the annulus based on the comparison; and
based on the command signal, operating the pressure regulator valve in one or more steps and at predefined time intervals to thereby selectively bleed an annulus fluid from the annulus to thereby prevent rapid decompression of the annulus and protect a power cable extending within the annulus to a downhole electrical submersible pump (ESP) assembly from damage.
