... be constructed without tremendous simplifications. The new proposed approach uses a 3D parameterization of the subsurface yielding a grid that minimizes the distortions of distances imposed by geostatistical simulation algorithms. These new Geologic Grids allow the construction of robust reservoir models...

Paper Number: SPE-102819-MS
.... This approach optimizes the system performance if all bits are equally important and need to be protected equally against transmission errors. Unfortunately, this criterion does not mean that high fidelity signals result. This paper first presents the mean-squared error (MSE) distortion as a fidelity measure...

... perforations. Fluid gradient changes in build up tests between the pressure gauge and the tested zone as a result of fluid interface in the wellbore falling back to resevoir fluid contact, may significantly distort the recorded pressure. The distortion is dependant on reservoir permeability and water or gas...

... on the resistivity of the formation is represented by the second spacial derivative of the casing voltage that is generally small. This makes the evaluation of possible distortions arising from different kinds of casing imperfections important. These imperfections include casing collars, corrosion, perforations, etc...

... which roughly corresponds to the fluid critical pressure. Although the pressure response for a constant rate drawdown may be only minimally affected, there is a major distortion of the pressure response during the buildup period. This distortion could easily be confused with reservoir heterogeneities...
