“…4. Recent modeling work mainly focus on reproduce the sedimentological characteristics of deepwater lobe reservoirs, while other factors, such as topography (e.g., salt domes) and structural factors, could also play an important role in controlling the final reservoir architectures (Pan et al 2012). Modeling methods incorporating such factors are still scarce; besides, more attention should be paid to model the reservoir dynamic behaviors.…”

Deepwater turbidite lobe reservoirs have massive hydrocarbon potential and represent one of the most promising exploration targets for hydrocarbon industry. Key elements of turbidite lobes internal heterogeneity include the architectural hierarchy and complex amalgamations at each hierarchical level leading to the complex distribution of shale drapes. Due to limitation of data, to build models realistically honoring the reservoir architecture provides an effective way to reduce risk and improve hydrocarbon recovery. A variety of modeling techniques on turbidite lobes exist and can be broadly grouped into pixel-based, process-based, process-oriented, surface-based, object-based and a hybrid approach of two or more of these methods. The rationale and working process of methods is reviewed, along with their pros and cons. In terms of geological realism, object-based models can capture the most realistic architectures, including the multiple hierarchy and the amalgamations at different hierarchical levels. In terms of data conditioning, pixel-based and multiple-point statistics methods could honor the input data to the best degree. In practical, different methods should be adopted depending on the goal of the project. Such a review could improve the understanding of existing modeling methods on turbidite lobes and could benefit the hydrocarbon exploration activities of such reservoirs in offshore China.

“…The accurate representation of intersecting faults within the mesh becomes challenging due to limited and fragmented data, requiring specialized techniques and methodologies to overcome these obstacles to achieve a reliable and precise mesh generation process [ 20 , 21 ]. The fault model describes the contact relationship and geometry between faults, and the construction of the fault model is based on the establishment of a 3D geological model to provide constraints for the generation of the ground level [ 22 , 23 ]. The construction of complex fault surfaces and the establishment of topological relationships of the elements of the geological body, that is, the establishment of topological relationships between intersecting fault surfaces, between fault surfaces and ground levels, and stratigraphic surfaces, are the core of the entire 3D modeling [ 24 , 25 ].…”

As the geological fault surface divides the 3D space of stratified ores and rocks into complex spatial surface domains, it is necessary to fully consider the spatial relationship between intersecting fault zones and geological bodies in the process of 3D modeling, and how to accurately establish the 3D finite element mesh of geological bodies in intersecting fault zones is a difficult point in modeling complex geological structure. The laminated geological body in intersecting fault zone is a multifaceted domain grid model consisting of a ground-level grid, a geological fault plane grid, and a range grid. By analyzing the spatial relationship between the geological interfaces of the intersecting fault zones, a closed manifold processing method is proposed to establish the closed manifold spatial surface model of the intersecting fault zones, based on which the closed spatial surface model is tetrahedrally divided to establish a 3D solid model. Finally, the 3D solid model is imported into Ansys to generate a 3D finite element mesh. VC++ is used as the development platform for programming, to realize the generation and closed manifold processing of ground level and geological fault surfaces, and use TetGen library to generate finite element mesh based on irregular tetrahedron. Taking an intersecting fault zone in an open-pit mine as an example, the 3D finite element mesh of laminated geological bodies in the intersecting fault zone is established successfully. This method provides an effective and feasible solution for generating accurate 3D finite element meshes in complex stratigraphic spaces based on closed manifold processing.

“…In recent years, domestic and foreign scholars have absorbed theories and technologies such as computer visualization and graphic imaging to conduct research on the theory and methods of true three-dimensional geoscience modeling. At the same time, scholars have conducted beneficial explorations in the expression and organization of topological relationships among geological objects [6][7][8][9][10] . It should be noted that 3D visualization of geological modeling and 3D geographic information systems are two high-tech fields that are currently developing in parallel within the field of geosciences.…”
