KronosFlow
When it comes to assess tectonically complex basins, conventional basin models are not sufficient as they do not accurately manage the combination of vertical and horizontal displacements. The vertical shear backstripping method commonly used for basin reconstruction cannot be applied and a real step by step restoration is required.
KronosFlowTM stands out from other restoration packages through its ability to honor the structural restoration of a basin without compromising the quality of the petroleum system modeling. Combining several geometrical and mechanical methods, KronosFlowTM is indeed able to provide geologically valid scenarios with the numerous deformation steps required for basin modeling while preserving the deformation of the mesh for accurate mass balance. This is achieved with a new meshing technology based on topology preservation with deformation. This mesh tracking is critical to properly take into account porous medium deformation, heat transfer, hydrocarbon generation and fluids migration through geological times. It allows quantitative predictions on pressure generation and hydrocarbon accumulations.
Ergonomics is a critical aspect of these workflows combining structural restoration with basin modeling and KronosFlowTM is a real game changer in terms of user-friendliness for producing kinematics. With ergonomics close to drawing software solutions, KronosFlowTM features innovative source to target definition functionalities, allowing to restore very rapidly multiple fault blocks whatever the structural complexity. KronosFlowTM also features many facilities for erosion restoration but also redrawing options for ductile deformation or direct edition when necessary. Decompaction is accounted for through the restoration process and section consistency and compatibility with TemisFlowTM basin simulator is automatically unsured.
A Scenario Manager automatically records all user’s operations, allowing going back and forth, testing various hypotheses and comparing deformation methods and approaches. This innovative methodology is a major step forward as basin modeling is a discipline involving a lot of uncertainties, structural interpretation and tectonic history being major ones.
A major functionality of the tool is also its ability to add additional layers to an already restored section with an automatic generation of additional steps. It is particularly powerful to add all the details required for basin modeling such as source rocks or thin reservoir layers.
Developed on the same platform, the OpenFlow Suite, KronosFlowTM is by nature integrated to TemisFlowTM 2D Complex Tectonics for basin and petroleum system assessment. TemisFlowTM 2D Complex Tectonics is a specific module of TemisFlowTMwhich features all necessary tools to manage lithologies, kerogens and fluids information of KronosFlowTMmodels. It allows defining faults behavior through time and launching temperature, pressure, expulsion and migration simulations with its cutting-edge calculator developed especially for complex tectonics. Running on unstructured meshes and offering a unique modeling of faults properties through time, this technology allows not only accounting properly for structures geometries at present day and through time but also simulating faults impact on water and hydrocarbon flows with a rigorous approach. All TemisFlowTM post-processing tools have been adapted to KronosFlowTM meshes for an efficient analysis and understanding of the results (log extraction, cell history, reporting...).
