Abstract: A method for downhole fluid analysis by optical spectroscopy with photoacoustic detection includes positioning a photoacoustic system within a wellbore, applying a laser pulse to the fluid sample using the pulsed laser system, detecting, by the acoustic sensor, a time-resolved acoustic pulse generated by absorption of the laser pulse by the fluid sample, and determining a property of the fluid sample using the detected time resolved acoustic pulse. The photoacoustic system includes a pulsed laser system and an acoustic sensor.
