Previous HitSeismicNext Hit Modeling of Petrophysical and Stratal Complexity of Isolated Carbonate Platforms

Abstract

Previous HitSeismicNext Hit data provide a fundamental means for visualizing and interpreting subsurface reservoirs. Whereas criteria for defining Previous HitseismicNext Hit stratigraphy in isolated carbonate platforms are well-defined, the role of facies and petrophysical variability on Previous HitseismicNext Hit character is less constrained. To address this unknown, this project builds Previous HitseismicNext Hit models and evaluates Previous HitseismicNext Hit attributes to explore how complexity in facies (size, distribution, and stacking patterns) and diagenesis (and porosity) might be recognized from Previous HitseismicNext Hit data in subsurface reservoirs. In sampling a range of variability through the suite of simulations, the project explores a spectrum of potential ‘geologic realizations,’ or scenarios that could be encountered in the geologic record of reservoir analogs. Facies morphometrics from Holocene systems and data from Devonian and Miocene analogs provide fundamental spatial, stratigraphic (Previous HitverticalNext Hit patterns) and petrophysical (porosity-velocity) input for the suite of Previous HitseismicNext Hit forward models. Previous HitSeismicNext Hit character is evaluated and quantified through Previous HitseismicNext Hit attribute analysis. Comparison between Previous HitseismicNext Hit attributes and the known (modeled) geologic variability quantifies geologic controls on Previous HitseismicNext Hit character. As such, quantitative and qualitative insights of the role of geology on Previous HitseismicNext Hit expression are applicable to exploration, development, and production settings, providing means for refined interpretations of Previous HitseismicTop data.
