... candidate seal repair materials. This model will be used to gain an understanding of the wellbore microannulus compressibility and permeability. The second is a field scale model that uses the stratigraphy, material properties, and injection history from a pilot CO 2 injection operation to develop stress...

.... Using this insight we are able to develop methods to intelligently generate units of mechanical stratigraphy, dependent on the model application, that are based on a distribution of mechanical properties with depth. To help validate the numerical methods used to "average" mechanical properties...

... of geologic structures over a wide range of scales, including the prediction of the onset of failure, and the type and abundance of deformation features [7- 13]. In particular, finite element modeling allows complex geometries (e.g., non-planar faults, mechanical stratigraphy) to be combined with realistic...

... ABSTRACT: Shaft closure measurements are presented which are based on a rather unusual emplacement of very early time closure points. These data are in good agreement with calculations based on the prediction techniques developed for underground rooms in salt using a complete stratigraphy...

... ABSTRACT ABSTRACT: The discrepancies between predicted and measured WIPP in situ Room D closures are markedly reduced through the use of a Tresca flow potential, an improved small strain constitutive model, an improved set of material parameters, and a modified stratigraphy. 1 INTRODUCTION...

... potash mines have indicated that clay underlying stiff anhydrite is a normal characteristic of the stratigraphy in the Salado Formation of the Delaware Basin. These inspections have, in addition, indicated that the thickness of the clays underlying the anhydrite are not con- sistent. This field...

..., measurements or rib in high walls, roof stratigraphy, and clay veins in coal measures have been accomplished. It is this work that will be discussed in this paper. The work in coal mines was started about two years ago with a contract to use a commercial radar to measure coal thickness in a mine roof. Figure 1...
