A thin-bed laminated shaly-sand reservoir of the Miocene formation was evaluated using two methods: high resolution microresistivity data from XRMI tool and conventional well logs. Based on data, Earth model defined in a way that allowed analyzed interval to be subdivided into thin layers sandstones, mudstones, claystones. Theoretical logs gamma ray, bulk density, horizontal vertical resistivit...

reservoir permeability is a critical parameter for characterization of the hydrocarbon reservoirs. in fact, determination of permeability is a crucial task in reserve estimation, production and development. traditional methods for permeability prediction are well log and core data analysis which are very expensive and time-consuming. well log data is an alternative approach for prediction of pe...

Abstract A series of novel heuristic numerical tools were adopted to tackle the setback permeability estimation in carbonate reservoirs compared classical methods. To that end, a comprehensive data set petrophysical including core and log two wells was situated Marun Oil Field. Both wells, Well#1 Well#2 , completed Bangestan reservoir, having broad diversity facies. In light high Lorenz coeffic...

Well logs are geophysical measurements of rock properties acquired continuously along a borehole. Because the physics underlying their operation, borehole logging instruments perform local spatial averages in vicinity borehole, yielding well that often affected by tool design, layer boundaries, environmental conditions and mud-filtrate invasion. Such effects ubiquitous can lead to errors petrop...
