Advances have been made to temperature monitoring with thernapplication of distributed temperature sensing with fiber opticsrnover the length of the wellbore to provide data for analysis ofrnthe well conditions. With this method, an optical fiber tornmonitor temperature over the entire length of a well isrninstalled. Custom visualization and analysis software thenrnuses the distributed temperature sensing data that is retrievedrnto perform analysis of well conditions in environments inrnwhich heat management is needed.rnThe capability to retrieve real-time data allows use ofrnvisualization and analytical software to provide rapidrnqualitative analysis prior to obtaining final quantitative results.rnThis process enables improvement of heat management inrnheavy oil wells by detection of problem areas within the well.rnThe improvements are provided by the capability to compare arnlarge number of data sets.rnThe fiber-optic technology was initially deployed in arnsteamflood well in Bakersfield, California over ten years ago.rnSince that time, the technology has been applied in manyrndifferent producing environments and has proven thatrnmonitoring of downhole conditions can provide valuablerninformation for production assessment.rnThis paper will discuss the significant benefits gained fromrnusing this technology in heavy-oil monitoring scenarios.
