Downhole sensing technology specialist, Well-SENSE, has launched its latest FiberLine Intervention (FLI) development, ‘Active FLI’.
Active FLI builds on the capability of Well-SENSE’s new fiber optic downhole data acquisition system with the addition of a range of discrete measurement devices, the company explains.
These include single point temperature and pressure sensors, with 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 capability extends the use of FLI to a wide variety of applications across the complete lifecycle of the well such as completion verification, production profiling or integrity investigation.
Well-SENSE CEO, Craig Feherty, said: “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 commercialisation 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; it’s almost like comparing a 3D colour video to a black and white photograph.”
According to the company, the FLI is a complete intervention system and 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.
