Abstract: A technique provides protection against unwanted conditions in wellhead structures and other structures. According to the technique, a system provides a feed through in a wellhead structure or other type of structure. The feed through may accommodate a communication line routed therethrough. A closing device is positioned in the structure at a location to enable closing of the feed through via the closing device. Additionally, a condition-sensitive device is operatively engaged with the closing device to initiate actuation of the closing device once the condition-sensitive device is exposed to a predetermined condition. Upon exposure to the predetermined condition, the condition-sensitive device initiates closing of the feed through via the closing device.

Abstract: A multiple sensor fiber optic sensing system includes an optical fiber having at least first fiber optic sensors and second fiber optic sensors deployed along its length. In response to an interrogating pulse, the first fiber optic sensors generate responses in a first optical spectrum window, and the second fiber optic sensors generate responses in a second, different optical spectrum window. The responses in the first optical spectrum window are measured in a first optical spectrum channel, and the responses in the second optical spectrum window are measure in a second, different optical spectrum channel and provide simultaneous indications of one or more parameters, such as temperature and pressure, in the environment in which the sensors are deployed.

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.

Abstract: The disclosure relates to a system, downhole device and method for monitoring a wellbore, in particular in a lateral section, during stimulation, with an 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 cable is retrieved by exerting a traction force. The disclosure also relates to a downhole device for receiving a cable and retainers to maintain the cable and having a weakpoint configured to break when subjected to a force along the longitudinal axis greater than a predetermined threshold. The system comprises 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.

Abstract: A well-logging system includes a first downhole tool coupled to a first cable for conveying the first downhole tool along a wellbore. A second downhole tool having a housing is coupled to a second cable for conveying the second downhole tool along the wellbore. The well-logging system includes a cable guide having a chassis structure coupled to the housing and a sleeve coupled to the chassis structure and disposed about the first cable. The first cable is configured to translate along the sleeve such that the sleeve facilitates guided movement of the first downhole tool relative to the second downhole tool.
