Survey and study of porosity and the form and the size of that in oil and gas reservoirs are important due to its key role in reservoir quality and productivity. in this paper, unlike conventional methods of using cores to recognize the geometry and morphology of porosity, fms image log and thin sections of cuttings from drilling are used. after determining the overall dimension of the porosity shown as black patches and spots by fms log, the shape and the size of the porosity was studied in the form of petrological study, based on thin sections from mozdouran reservoir formation(lower jurassic) in one of the gas fields in the east of kopedagh basin. tracing and comparing of the results of the two methods show a good correlation for determining the type and geometry of porosity. data fusion of fms log data with petrological studies of thin sections of cuttings from drilling has advantages the most important of which is the possibility of replacement of core with fms log and thin sections in order to determining the geometry of porosity.
