March 7,2001 Case Study 2,3 Porosity Estimation Leading Edge April 2000 1. Constrained sparse spike and stochastic inversion two approaches to the inverse problem when resolution is limited- emphasis is on comparing the results of these methods 2. Wavelet extracted with well crossing the seismic trace.
Prior model uses well, plus geologic interpretation.
Figure 4 shows the details where a well is available. Ideas of constraints and general appearance of a good result. Lab measurements on velocities, density, proposity, permeability. General results from Figure 5 is that velocity is a good indicator of porosity. From figure 6 the indication is that the result is consistent with other studies.
