1. A method, comprising:
verifying calibration of a photoacoustic device when a selected reference peak shifts or at an end of a specified verification time interval, and requesting a calibration process when the verifying so indicates;
collecting extracted material from a location in a subterranean formation, wherein the location is proximate a position of a hydrocarbon operation within a borehole;
preparing the extracted material, wherein extraneous material is removed;
putting the extracted material into the photoacoustic device;
initiating a photoacoustic process utilizing the extracted material; and
generating results from an analyzation of the photoacoustic process.
