US Patent Issued to Baker Hughes Oilfield Operations on May 19 for "Pressure tuned infrared light emitting diode for downhole spectroscopy" (Texas Inventor)

ALEXANDRIA, Va., May 19 -- United States Patent no. 12,631,111, issued on May 19, was assigned to Baker Hughes Oilfield Operations LLC (Houston).

"Pressure tuned infrared light emitting diode for downhole spectroscopy" was invented by Rocco DiFoggio (Houston).

According to the abstract* released by the U.S. Patent & Trademark Office: "Fluid is sampled from a subterranean formation with a downhole tool from inside a wellbore intersecting the formation. The fluid is analyzed by a spectrometer inside the downhole tool. A light source in the spectrometer is pressure tuned to compensate for a change in wavelength of the output light due to a temperature change in the wellbore, and overlap with a compound of interest or analyte absorption band....
