Abstract

Recognition of Subsurface fracture system is of prime importance for developing carbonate hydrocarbon-bearing fields. The purpose of this study was to employ XRMI in order to provide details of fault related fractures characterization. Also faults and fractures were recognized and assessed through analyze raw data by means of special software at one well of a carbonate reservoir locating in SW oilfield of Iran. Much more open fractures associated with eight possible faults were observed within this well at the different depths. A total six of the observed possible faults had followed the general Zagros folding trend. The validation of the obtained results was checked with the comparison of other available field evidences (i.e. mud loss data). The results demonstrated that distinguished fracturing system provides a realistic and accurate description of target area.
