Downhole sensing technology specialist Well-SENSE has launched its latest FiberLine Intervention (FLI) development, Active FLI at ADIPEC.

“Earlier this year, we secured significant investment from Saudi Aramco Energy Ventures (SAEV) which has allowed us to further develop FLI and is supporting the commercialization process,” said Well-SENSE CEO, Craig Feherty.

Active FLI adds a range of discrete measurement devices to Well-SENSE’s fiber optic downhole data acquisition system, including single point temperature and pressure sensors and the addition of a casing collar locator for depth correlation. The tools are located in the FLI probe to capture measurements as it descends downhole and complement the distributed sensing which takes place along the length of the fiber optic lines deployed in the well by FLI.

The combination of single point and distributed data provides enhanced well intelligence and allows events occurring in the well to be precisely located, verified and quantified via different data sets.

“This creates a much richer picture; it’s almost like comparing a 3D color video to a black and white photograph,” Feherty explained. “Add to this, our simple, user-friendly plug and play deployment system and you end up with a customer controlled, low risk, low cost system which can give you a clear insight into every downhole scenario across the lifecycle of the well.”

FLI's capability is now extended to a wide variety of applications across the complete lifecycle of the well, such as completion verification, production profiling or integrity investigation.

The customer operated plug and play complete intervention system 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 complete 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 disposable; they can be be left in the well to dissolve following project completion.
