1. A method comprising:
drilling a wellbore of a well from a surface to form a fluid communication path from a pressurized reservoir to the surface;
installing a first pipe component in the wellbore to form a first annular space between a pipe outside diameter and the wellbore wherein the first annular space is in fluid communication with the pressurized reservoir;
transmitting, by a control system, a first command to a pressure recorder configured to generate annular pressure data of an annular fluid in the first annular space;
transmitting, by the control system, a second command to the pressure recorder, wherein the first command and the second command are separated by a predetermined time duration;
generating, in response to receipt of the first command, first annular first pressure data using the pressure recorder;
generating, in response to receipt of the second command, first annular second pressure data using the pressure recorder;
obtaining, by the control system in response to transmitting the first command, the first annular first pressure data from the pressure recorder;
obtaining, by the control system in response to transmitting the second command, the first annular second pressure data from the pressure recorder;
comparing, using the control system, the first annular first pressure data and the first annular second pressure data with a first set of predetermined criteria;
controlling, using the control system, a first control valve in fluid communication with the first annular space in response to the comparing; and
filling a relief tank using the annular fluid flowing through a fluid conduit in fluid communication with the first annular space, the first control valve, and the relief tank.
