SDM AND PETROPHYSICAL CONSTRAINTS Prestack Depth Migration and velocity model analysis constraints beyond the seismic resolution. A velocity V model is one the most important steps on the seismic processing workflow and a first fundamental phase of seismic imaging. The refinement of the V model follows in upgraded steps after residual statics corrections, repeated NMO correction, usual application of up to the 4th order moveout term as a function of Thomsen parameters in consideration of local and azimuthal anisotropy. In the Prestack depth and WE Migration wide use is made of an objective cost functions that QC the refinement and convergence of the model to minimize the error through minimum admissible levels. A similar concept can be applied to FWI problems.

SDM is performed in the common offset domain with the construction of common image gathers. A model for an objective function is here presented which integrates rock physics and petrophysical constraint to the macro seismic velocity model, thus relating geomacrosystems and microsystem in a unique model relating migration and formation evaluation concepts as input in the V model.

LookIn todays environment, the hand calculator on our desk has more computational power than did the computer that first sent man to the moon. We benefit in many ways from this power, but it behooves us to remember the basics. Quick Look interpretations serve many functions. Legacy files will often include QL results, which should be well understood before moving forward. Not only do the QL interpretations provide a rapid first look at a well, but they also serve as a benchmark against modern computerized results. When the basic porosity logs are displayed appropriately, PhiQL is estimated by simply drawing a line down the middle and Rw follows from a ratio of the resistivities. These calculations may be invoked even as depth shifting splicing is done, so that just as soon as the digital database is complete, we are also ready to characterize first pass the porosity, RwResistivity Ratio and SwResistivity Ratio. Later final calculations will typically be more sophisticated, but even then the QL estimates will provide a valuable benchmark. For example, we have personally observed, repeatedly, probabilistic results that predicted hydrocarbons across an interval for which the QL was wet the QL was correct. Not to demean probabilistic models at all, but those calculations can be very dependent upon initialization parameters. Quick Look algorithms do not replace modern tools and techniques, but rather supplement them. Understanding Buckles, Morris Biggs and the many other Yesterdays Hero provide the baseline upon which we can better interpret todays high technology options.

In this work we present an approach for rock quality determination using NMR measurements on core plug samples. We measured the NMR T2 relaxation in the laboratory for several core plug samples from clastic reservoirs in Eastern Venezuela. Cabbage Patch Lil Sprouts Dolls. In addition, a standard petrofacies classification for the whole sample set was performed based on the main pore throat radius for 4. After analyzing the NMR results of samples of each petrofacies we found characteristic patterns in their T2 distribution curves. A detailed study reveals that the new classification can be defined on the basis of the ratio of free fluid index FFI over bound fluid volume BFV, already explicit in the Timur Coates permeability equation.

Neurale in discussion with Robert Garotta WEAK POLAR ANISOTROPY ISSUES THE VOLUME OF INVESTIGATIONMany seismic anisotropy and rock physics studies are related to laboratory tests solving for various anisotropy models VTI, HTI, Orthorhombic, Triclinic etc. Theoretical Models are upscaled at the seismic resolution scale. Rock physics models have also been developed Sequential Effective Medium Modelling which are appear to be most representative of the formation in place. From these assumptions a first observation a geoscientist would probably afford is which is the volume of investigation for anisotropy models in the contest of 3. D seismic measurements We solve also this issue considering several anisotropy models but certainly starting from weak polar anisotropy. As far as the propagation is isotropic, two parameters only, are present in the non zero Cij values of the Chirstoffels matrix, most of them are zero. Anisotropy means non zero values of the, Thomsens parameters, moreover privileged orientations may exist. Since, are linked to Cij constants, previously non zero values become more complex, other ones are no longer zero. DOWNLOAD THE FULL ARTICLEIn the July 2.

D blocks X,Y,Z displaying color coded values of the elastic parameters VP, VS, and additional seismic attributes parameters related to rock physics, anisotropy, reservoir architecture. This is the context of one component P mode seismic, where only one component of the emerging wavefield is recorded. In the one component or P mode however we are faced with several problems like seismic noise cancellation time to depth conversion elastic inversion. In addition to the P mode wavefield, multi component seismic records reflectivities issued from other wavefields that include shear wave travel path. PSV mode whose PS conversion occurs at the reflection point is the most convenient one since it includes an upgoing shear mode travel path. DOWNLOAD THE FULL ARTICLEIn the March 2.

MIXTURE OF GAUSSIAN FITTING OF NMR SPECTRA FOR RETRIEVING FLUID DISTRIBUTIONSThe de convolution of low field NMR spectra, especially those obtained from borehole logging tools, is a very important procedure that can unveil information hidden in the T1, T2 or Diffusion. This information is associated with the determination of the spectral components present in the distributions that can be used to identify reservoir rock quality and fluid types. The fitting method presented in this paper uses as input only spectral data already available after inverting the NMR echo trains it identifies the bins where the spectral components are located and quantifies them in terms of height, mean and variance corresponding to the selected fitting curves.
