Well-SENSE, the downhole sensing technology specialist, has launched a new miniature optical gauge.

Well-SENSE launched a miniature optical pressure-temperature gauge, as part of its FiberLine Intervention (FLI) system, at the Offshore Technology Conference (OTC) in Houston.

The Well-SENSE optical gauge widens the well surveillance application envelope for FLI, both on and offshore, and aims to offer operators a low-cost and disposable alternative to both permanent downhole sensors and more traditional electronic logging devices.

The fiber Bragg grating based device is a robust optical gauge with no electronics, batteries, external connections or power supply required. It is integrated into the fiber line and aids well surveillance activities in harsh environments, including HPHT applications. Set as standard, the new gauge has the capability to measure up to 10,000psi and 150°C, with the option to enhance this further to 20,000psi and 300°C.
