Parallel-processing of invasion percolation for large-scale, high-resolution simulation of secondary hydrocarbon migration
A parallel-processing hydrocarbon (HC) migration and accumulation methodology is applied to basin data to determine migration pathways and traps for high-resolution petroleum system modeling. HC is determined in parallel to have been expelled in source rocks associated with a plurality of grid cells divided into one or more subdomains. Potential trap peaks are identified within the plurality of grid cells. An invasion percolation (IP) process is performed until the HC stops migrating upon arrival to the plurality of trap peaks. A determination is made as to whether the grid cells containing HC contains an excess volume of HC. An accumulation process is performed to model the filling of the HC at a trap associated with the identified potential trap peaks. The trap boundary cell list is updated in parallel together with an HC potential value. Trap filling terminates when excess HC is depleted or a spill point is reached. |

The metallic electron transport at the surface with good effective mobility can be effectively separated from the conduction of the bulk topological insulator and adjusted by field effect at a small gate voltage. Topological insulators, such as Bi2Se3, also have a magneto-electric effect that causes transistor threshold voltage shifts with external magnetic field. These properties are desirable for numerous microelectronic and nanoelectronic circuitry applications, among other applications. |

Interlocking, quick-release horizontal logistic track
A quick-release, horizontal logistic track having a coupling mechanism that allows two such quick-release logistic tracks to interlock so as to effectively form a continuous track that varies in length as a section of track is added or removed from the series. Installed, the multiple sections of quick-release logistic track become one integrated track that is flush from end to end on the same sidewall. The quick-release logistic track has two integral couplings that consist of a male coupling and a female coupling on opposing ends enabling the male end of a newly installed track in the series to be coupled to a female end of a separate track that is already anchored in a vertical logistic post slot. As the newly installed track's male end is coupled to the anchored female end the newly installed track's opposing female end is then anchored to an adjacent vertical logistic post slot. This method is repeated until the desired length of quick-release logistic track is satisfied. The male and female couplings on opposing ends of a track allow for only one end of a quick-release logistic track to be anchored in a vertical logistic post slot when attaching multiple tracks in a series to a sidewall. While the female coupling of one track is anchored in a vertical logistic post slot the male coupling of another track is able to leverage the female coupling's push, pull, and vertical forces by inserting itself. The male and female couplings allows for multiple tracks to be installed quickly and efficiently in a continuous series of tracks down one sidewall. |
