Latest Patents

One of Finfer's latest patents focuses on multi-phase flow-monitoring using an optical fiber distributed acoustic sensor. This invention provides a versatile 'tool-kit' of processing techniques that can be employed in different combinations based on specific circumstances. For instance, flow speed can be determined using eddy tracking techniques or speed of sound measurements. Additionally, the composition of the flow can be assessed through these measurements and by identifying turning points in the k-w curves, particularly in stratified multi-phase flows. The ability to combine these techniques allows for tailored solutions to meet particular flow sensing requirements, both on the surface and downhole. Once the flow speed is established, it can be multiplied by the interior cross-sectional area of the pipe to calculate the flow rate. If the density of the fluid is known, the mass flow rate can also be determined.

Another significant patent involves structure monitoring, which utilizes an optical fiber-based distributed acoustic sensor (DAS) extending along the length of a structure. This DAS can resolve separate acoustic signals with a spatial resolution of 1 meter along the fiber's length. It operates in conjunction with an acoustic positioning system to accurately determine the position of structures, such as sub-sea risers. Furthermore, the fiber can detect lower frequency mechanical vibrations, including resonant mode vibrations induced by movements in the surrounding medium. By integrating vibration detection with acoustic positioning, comprehensive structure shape monitoring can be achieved, which is beneficial for vortex-induced vibration (VIV) visualization, fatigue analysis, and other advanced applications.
