Abstract

Micro-resistivity borehole imaging tools have evolved over the past 30 years from basic dipmeters, with three arms each bearing a single electrode, to today's advanced micro-resistivity tools with rows of electrodes on multiple articulated arms. These advancements in imaging tool technologies are paralleled by transformations in the acquisition and Previous HitprocessingNext Hit software. This paper summarizes the data Previous HitqualityNext Hit issues that can occur during image acquisition, transmission and Previous HitprocessingNext Hit and the impact they have on the reliability of the final interpretation. These data issues may be obvious when related to the malfunctioning of imaging tools, but more subtle failures can also give misleading results. In many cases, these subtle failures may only be identified if the utmost attention is paid to comprehensive image data Previous HitqualityNext Hit Previous HitcontrolNext Hit and verification. These data Previous HitqualityNext Hit issues are not necessarily related to hardware but to acquisition or Previous HitprocessingTop software. If overlooked, these issues can have detrimental consequences in exploration and development applications of image logs, including erroneous dip magnitude and dip azimuth results.
