Quantitative Geology and resolution enhancements from image logs used in processing of thin layers.
MetadataVis full innførsel
In this project I will focus on the quantitative application of FMI log as an addition of its use as a imaging log. The Fullbore Formation Microimaging is today commonly only used for qualitative studies of the borehole, where measurements from the 192 electrodes are placed together to form an image of the borehole wall. The FMI has a higher resolution than regular resistivity logs and may read layers as thin as 0.5cm, or 0.2 inches. For this project, we will be using the mean of twelve resistivity measure traces from one of the eight pads on the FMI logging tool, (Nielsen, 2013).This project will both look at how the FMI log may be calibrated to true resistivity by using the resistivity logs. Both measuring in the flushed zone the micro resistivity log should be a good match for the FMI log. Calibrating it to the deep resistivity, this project will try to find a parameter making up for the differences between the flushed zone and the uninvaded zone. And do further work on the interval activity evaluation from the author s project form autumn 2013 finding an activity parameter distinguishing between thick intervals with none or few thin layers and thick intervals of many thin layers. Afterwards the FMI log calibrated to true resistivity will be used in calculations for Vshale, Sw, So, Sxo and N/G evaluated beside the same calculations done with the corresponding resistivity logs.
