A Safire in the Rough
2014 R&D 100 Winner
A multi-phase flow meter, Los Alamos National Laboratory’s Safire provides noninvasive, real-time and accurate estimates of oil production for every well. Jointly developed with Chevron ETC and GE Measurement & Control, Safire achieves measurement rates as high as 100 readings/sec, including computation time.
Safire is based on SFAI, swept frequency acoustic interferometry. SFAI uses frequency-chirp signal propagation (wideband ultrasonic frequency) through a multi-phase medium to extract frequency-dependent physical properties of said medium. Reservoir engineers then use the propagation time and the attenuation of the chirp signal as a function of frequency to extract both fluid flow and multi-phase fluid composition information.
Designed to be simple to use, Safire enables continuous measurements in fast-changing oil flows in rod-pumped wells, as well as other wells. Safire’s ability to provide accurate, real-time volumetric measurements of oil flow from wells means better reservoir management, accelerated production and huge cost savings by eliminating environmentally unsafe separations tank.
