Abstract: A visualization application will generate a Virtual Core representing a compilation of any formation property data, the compilation being a 2 and ½ D representation of any formation property. The compilation is generated by creating, in response to an integrated formation evaluation in 1D, a 2 and ½ D representation of each 1D formation property in the 1D formation evaluation, when the 1D property can be related to the 2 and ½ D physical magnitude combining the 2 and ½ D physical magnitude image with the 1D facies log thereby generating a 2 and ½ D facies image. The Software will also generate a Virtual Plug representing an average estimate of all formation properties over a prescribed surface or volume in the vicinity of a selection made on the compilation (i.e., on the Virtual Core). When an interaction with the Virtual Core occurs, all results generated by those interactions will be restored.

Abstract: A method of producing images of formations surrounding a borehole, comprises: obtaining values of a first parameter in the borehole as a function of depth and azimuth at a first resolution; obtaining values of a second parameter in the borehole as a function of depth only at a second resolution; establishing a relationship between the first and second parameters at a matched resolution; using the relationship to derive values of the second parameter as a function of depth and azimuth; and producing an image of the second parameter as a function of depth and azimuth using the derived values of the second parameter.

Abstract: An integrated interpretation methodology is described that evaluates carbonate reservoirs. The methodology consists of first classifying the rock facies. A geometrical model specific to the classification is then used to predict the response of the rock to a variety of stimuli. A reconstruction of the geometrical model is made by comparing the measurements with the model predictions. The model is then used to predict the resistivity and the hydraulic transport properties of the rock, thereby enabling computation of both the reserves and their production behavior.

Abstract: An acoustical method of determining the spherical, or vuggy, porosity in carbonate rock formations, as a function of shear modulus. Total porosity and shear modulus of the formation is measured. Then the intrinsic granular porosity, dry bulk modulus, and spherical porosity are calculated. The carbonate rock is modeled, consisting of a primary host medium composed of carbonate grains with intergranular porosity between them. The model is easily modified to account for the case of intercrystalline microporosity existing within the grains, in addition to the intergranular porosity between them.
