Abstract

A system and method are provided for monitoring a wellbore in a lateral section, during stimulation, with equipment enabling retrieval in many conditions. The method includes monitoring the wellbore with a distributed fiber optic sensor to determine one or more characteristics of the stimulation operation using detected backscattered optical signals on the distributed fiber optic sensor. The method also includes retrieving a cable by exerting a traction force. A downhole device is provided for receiving the cable and includes retainers to maintain the cable and also includes a weakpoint configured to break when subjected to a force along a longitudinal axis of the downhole device that is greater than a predetermined threshold. The system includes the cable having the distributed fiber optic sensor, the downhole device, and a surface monitoring system for determining the characteristic of the stimulation operation using detected backscattered optical signals on the distributed fiber optic sensor.
