An application of categorical indicator geostaistics for facies modeling in sand-rich turbidite sytems
- SPE, Richardson, TX (United States)
A case study is presented in which a two-stage stochastic modeling approach was employed for modeling heterogeneities in a deep-water Gulf of Mexico field. The hydrocarbon-bearing intervals of this field were deposited as turbidites and exhibit high net sand/gross interval (net/gross) ratios. In the first stage, a new facies indicator geostatistical method was used to model uncertainties associated with facies maps derived from seismic amplitudes. The concept of pseudo-wells is introduced for capturing geologic features and constraining the stochastic realizations. In the second modeling stage, synthetic stratigraphic columns based on whole core descriptions were used to capture fine-scale heterogeneities in cross-sectional panels. These cross-sections were subjected to flow simulations, yielding scaled-up values of single and two-phase flow parameters. Results from both stages were combined into a full-field 3-D reservoir simulation model.
