ABU DHABI, UAE – Downhole sensing technology specialist Well-SENSE has unveiled its latest FiberLine Intervention (FLI) development, ‘Active FLI’ at the ADIPEC exhibition.

This is said to build on the capability of the company’s fiber-optic downhole data acquisition system through the addition of a range of discrete measurement devices such as single point temperature and pressure sensors and a casing collar locator for depth correlation.

The tools, located in the FLI probe, take measurements as it descends downhole and are said to complement the distributed sensing that occurs along the length of the fiber-optic lines deployed in the well.

Combining single point and distributed data leads to enhanced well intelligence, Well-SENSE claims, allowing the operator to pinpoint events occurring in the well and to verify and quantify these via different data sets.

In this way, FLI is extended to applications such as completion verification, production profiling, and integrity investigation.

Well-SENSE CEO Craig Feherty said: “Earlier this year we secured significant investment fromSaudi Aramco Energy Ventures which has allowed us to further develop FLI and is supporting the commercialization process.

“Active FLI is the only downhole sensing system on the market to combine distributed and single point data acquisition in one low cost disposable tool. This creates a much richer picture.”

FLI does not rely on wireline, slickline or coiled tubing for deployment. It places bare fiber-optic lines into oil and gas wells to capture high-definition, real-time data.

The length of the fiber acts as a sensor and delivers a comprehensive temperature, pressure and acoustic profile of the well from top to bottom, simultaneously, over time.

The fiber, probe and all downhole electronics are single use and are left in the well to dissolve following the conclusion of the program.
