Accurate permeability estimation has always been a concern in determining flow units, assigning appropriate capillary pressure andrelative permeability curves to reservoir rock types, geological modeling, and dynamic simulation.Acoustic method can be used as analternative and effective tool for permeability determination. In this study, a four-step approach is proposed for permeability estimati...

the prediction of lithology is necessary in all areas of petroleum engineering. this means that todesign a project in any branch of petroleum engineering, the lithology must be well known. supportvector machines (svm’s) use an analytical approach to classification based on statistical learningtheory, the principles of structural risk minimization, and empirical risk minimization. in thisresearc...

  Application of Archie equation in carbonate reservoirs is not easy due to high dependence of its parameters on carbonate characteristics. Carbonates are very heterogeneous in nature and hydrocarbon reserve estimation in these reservoirs of mostly oil-wet and intermediate-wet is highly influenced by the input values of saturation exponent. To our knowledge, non representative oils have been us...

Abstract This work focuses on the carbonate factories constituting Pietra di Finale Fm cropping out in Ligurian Alps. unit constituted a mixed carbonate–siliciclastic coastal wedge developed during Middle Miocene. The characterizing of clearly differ from those systems and platforms developing Miocene elsewhere Mediterranean area. Here, Alps, euphotic factory does not show any evidence seagrass...

The seabed of the Pontine Archipelago (Tyrrhenian Sea) insular shelf is peculiar as it characterized by a mixed siliciclastic–carbonate sedimentation. In order to reconstruct Late Quaternary paleoenvironmental evolution Archipelago, this study investigates succession facies recorded two sediment cores. For purpose, benthic foraminifera and rhodoliths assemblages were considered. cores (post-Las...

Two separate and distinct diamictite-rich units occur in the mixed carbonate-siliciclastic PolarisbreenGroup, which comprises the top kilometer of47 km of Neoproterozoic strata in the northeast of the Svalbard archipelago.The platformal succession accumulated on the windward, tropical to subtropical margin of Laurentia.The older PetrovbreenMember is a thin glacimarine diamictite that lacks a ca...

This study focuses on the mechanisms responsible for enhanced oil recovery (EOR) from fractured carbonate reservoirs by surfactant solutions, and methods to screen for effective chemical formulations quickly. One key to this EOR process is the surfactant solution reversing the wettability of the carbonate surfaces from less water-wet to more water-wet conditions. This effect allows the aqueous ...
