When used together, these programs help the user to answer a broad range of questions about a simulated petroleum system.
Source Rock Generation and Expulsion
One of the first tasks in most petroleum systems evaluations is to understand the maturity, timing and volumetric potential of the relevant source rocks. This task often begins with 1-D models constructed from well penetrations or from synthetic stratigraphic sections derived from seismic data. These workflows are fully supported in BasinMod, a project-based basin modeling system that allows the user to construct and work with multiple 1-D models at the same time. The project-based approach allows the user to easily visualize spatial relationships between wells and to make gridded maps using any calculated values in the wells. This means that maps such as source rock maturity, timing of generation or volumes of oil expelled can be quickly created within the basin modeling system with no need for exporting data to external mapping packages. The maps are automatically updated as new 1-D models are added to the project.
If more detailed maps are desired, users can take advantage of the Batch Processing capabilities available in BasinView. The batch processer divides the study area into a large number of nodes and then performs calculations at each node. These calculations can then be mapped using the extended gridding options available in BasinView. Source rock evaluations can also be performed in 2-D cross-sections with BasinMod 2-D.
Migration Pathway Analysis
Migration pathways can be modeled in cross-sections using BasinMod 2-D and with a map-based approach in BasinFlow. In areas with little structural complexity, BasinMod 2-D models can be constructed in only a few minutes by importing existing 1-D models from BasinMod. 2-D models with more complex structural styles can be constructed using the digitizing tools available in BasinMod 2-D. The import of SEGY seismic images is fully supported and can be used as a template for section digitizing and construction.
Fully-integrated within the BasinView application, BasinFlow takes a hydraulic potential approach to modeling petroleum migration within permeable carrier beds. Supported options include single- and two-phase migration, fetch area definition, and trap volumetrics. The BasinFlow migration algorithms are extremely computationally efficient - basin-scale simulations can easily be run in an hour or less, even on off-the-shelf desktop or laptop computers.
