1. A method for performing an oil field operation on a reservoir, comprising:

  • obtaining a first user objective identifying the oilfield operation;

    obtaining a first set of input data for performing the oilfield operation;

    selecting a first workflow for performing the oilfield operation based on the first user objective, wherein the first workflow is configured to build at least a 3D model of the reservoir for the first user objective and comprises a build model module and a tune model module;

    generating, using a processor of a computer system, a 1D petrophysical model of the reservoir by executing the build model module, wherein the 1D petrophysical model comprises a plurality of per unit of depth properties of the reservoir including porosity, rock type, saturation, lithology, and layering;

    generating, using the processor, the 3D model of the reservoir using the build model module to distribute the plurality of per unit of depth properties of the 1D petrophysical model in a 3D space defined by a first radius of investigation, the first radius of investigation defining the size of the 3D model;

    calibrating, using the processor, the 3D model using the tune model module, a plurality of modular dynamic tester (MDT) transient test data, and a historical response of the reservoir associated with the plurality of MDT transient test data by iteratively solving for a new value of horizontal permeability and a new value of vertical permeability, wherein iteratively solving for the new value of horizontal permeability and the new value of vertical permeability comprises;

    determining a plurality of residuals using the following equation;
