Abstract: Disclosed are systems and methods of monitoring a well that includes a production tubing installed in the well and supported by a wellhead with an annulus between the production tubing and a well casing. While the production tubing remains installed in the well, a valve of the wellhead is opened to provide access to the annulus through a side port of the wellhead. A cable guide is inserted through the valve, the cable guide including a conduit for inserting a sensing cable through the cable guide. A sensing cable is inserted through the conduit of the cable guide and into the annulus through the side port. One or more parameters of the well are measured using the sensing cable and signals representative of the parameters are transmitted along the sensing cable. The signals from the sensing cable are obtained and processed using a computing system to determine the parameters.
