“…Numerical methods were used to solve the above model. The numerical solution procedure was based on the finite volume method (FVM), which has a good local conservativeness and clear physics meaning (Versteeg and Malalasekera, 2007;Moukalled et al, 2016;Liu P. et al, 2017). Cell-centered variable arrangement method was used to store the unknowns at the centroids of grid elements (Fig.…”

Estimation of base level changes in geological records is an important topic for petroleum geologists. Taking the Paleocene Upper Lingfeng Member of Lishui Sag as an example, this paper conducted a base level reconstruction based on Basin Filling Modelling (BFM). The reconstruction was processed on the ground of a previously interpreted seismic stratigraphic framework with several assumptions and simplification.The BFM is implemented with a non-linear diffusion equation solver written in R coding that excels in shallow marine stratigraphic simulation. The modeled results fit the original stratigraphy very well. The BFM is a powerful tool for reconstructing the base level, and is an effective way to check the reasonableness of previous interpretations. Although simulation solutions may not be unique, the BFM still provides us a chance to gain some insights into the mechanism and dynamic details of the stratigraphy of sedimentary basins.

“…As an alternative method to direct measurement, empirical models can be applied to predict the absolute rock permeability from the porosity [50][51][52][53][54]. Among these models, the most widely used one is the so-called Kozeny-Carman equation [31,32,[55][56][57][58][59][60][61][62], which is written as per [51]:…”

“…The lattice Boltzmann approach has also been used to study the reactive transport process and fracture evolution at the pore scale [28,29]. At the continuum scale and field scale, Darcy's equation has usually been applied as a momentum equation [30][31][32]. Darcy's equation can be inaccurate for modeling fluid flow in carbonate formation due to its large-scale void space features that can also be enhanced dynamically due to dissolution processes.…”

Water–rock interactions can alter rock properties through chemical reactions during subsurface transport processes like geological CO2 sequestration (GCS), matrix acidizing, and waterflooding in carbonate formations. Dynamic changes in rock properties cause a failure of waterflooding and GCS and could also dramatically affect the efficiency of the acidizing. Efficient numerical simulations are thus essential to the optimized design of those subsurface processes. In this paper, we develop a three-dimensional (3D) numerical model for simulating the coupled processes of fluid flow and chemical reactions in fractured carbonate formations. In the proposed model, we employ the Stokes–Brinkman equation for momentum balance, which is a single-domain formulation for modeling fluid flow in fractured porous media. We then couple the Stokes–Brinkman equation with reactive-transport equations. The model can be formulated to describe linear as well as radial flow. We employ a decoupling procedure that sequentially solves the Stokes–Brinkman equation and the reactive transport equations. Numerical experiments show that the proposed method can model the coupled processes of fluid flow, solute transport, chemical reactions, and alterations of rock properties in both linear and radial flow scenarios. The rock heterogeneity and the mineral volume fractions are two important factors that significantly affect the structure of conductive channels.
