In the ‎wellbore, logs continuously measure physical properties of reservoir ‎while the properties change stepwise. This continuous representation ‎of logs may lead to ignorance of some high potential reservoir zones. ‎The main reasons for continuous nature of logs in laminated reservoirs ‎are the influence of shoulder beds on the reading of logging tools and ‎low vertical resolution of these devices.‎In this paper we optimized a Laplacian filter to detect bed boundaries ‎in conventional well logs. These blocking-based boundaries are ‎validated with FMI derived bed boundaries. Then the calculated ‎petrophysical properties including porosity and volume of minerals ‎and fluids are distributed into the detected beds. Comparison of ‎petrophysical interpretation of logs based on blocking and FMI ‎derived bedding showed that the petrophysical properties realistically ‎distributed into beds in layered reservoirs with the blocking technique. ‎The results also showed that blocking reduces the uncertainties, ‎because it realistically distribute the petrophysical properties inside real ‎geological beds and alter the noises.‎ UR - https://jsciences.ut.ac.ir/article_60751.html L1 - https://jsciences.ut.ac.ir/article_60751_1911a2f94be58b6dcb8370505bbc638d.pdf ER -
