Abstract

Enhancing resolution of distributed optical measurements along a wellbore can include acquiring optical signals during an acquisition time period, thereby producing a convolved profile along the wellbore, and deconvolving the profile using a first function corresponding to the acquisition time period, thereby determining a second function. Another method of enhancing resolution of distributed temperature measurements along a wellbore can include acquiring optical backscatter signals during at least first and second acquisition time periods, thereby producing respective first and second convolved temperature profiles along the wellbore; deconvolving the first temperature profile using a first function corresponding to the first time period, thereby determining a second function; and deconvolving the second temperature profile using the second function, thereby determining the first function corresponding to the second time period.
