An Inverse Stratigraphic Simulation Model – Is Stratigraphic Inversion Possible?
Energy Exploration & Exploitation, 1996 Inversion is a systematic method of determining values of process parameters of a forward model that allow a match between observed and modeled data. Historically, geologists have considered the stratigraphic record to be nonunique. That is, geologists have assumed that it is impossible to determine values for and separate stratigraphic process ...

The intrinsic rarity of equilibrium response in stratigraphic processes
Geosystems and GeoenvironmentConventional sequence stratigraphy is based, explicitly or implicitly, on the hypothesis that steady external forcing results in a steady stratigraphic configuration (equilibrium response), so that an unsteady stratigraphic configuration is usually ...

AdaHRBF v1.0: gradient-adaptive Hermite–Birkhoff radial basis function interpolants for three-dimensional stratigraphic implicit modeling [PDF]
Geoscientific Model Development, 2023 Three-dimensional (3D) stratigraphic modeling is capable of modeling the shape, topology, and other properties of strata in a digitalized manner. The implicit modeling approach is becoming the mainstream approach for 3D stratigraphic modeling, which ...

Porosity and permeability prediction through forward stratigraphic simulations using GPM™ and Petrel™: application in shallow marine depositional settings [PDF]
Geoscientific Model Development, 2021 The forward stratigraphic simulation approach is applied to predict porosity and permeability distribution. Synthetic well logs from the forward stratigraphic model served as secondary data to control porosity and permeability representation in the ...

Quaternary stratigraphic regionalization and comprehensive framework in Nanling and adjacent areas
地质科技通报, 2021 The Quaternary sediments in the Nanling and adjacent areas are dominated by alluvial, eluvium and cave deposits, which have lacked of a unified stratigraphic and chronological framework.Based on the results of field survey and research on profiles, the ...
