SYSTEMS AND METHODS FOR UTILIZING CELL BASED FLOW SIMULATION RESULTS TO CALCULATE STREAMLINE TRAJECTORIES

摘要

Systems and methods for utilizing finite difference stimulation results to compute streamline trajectories are described. One example of a method for calculating a streamline includes: initializing a seed point within a simulation grid cell; computing a velocity vector for the seed point; selecting an incremental distance in a direction of the velocity vector; computing coordinates for a new seed point location based on the incremental distance and the direction of the velocity vector; computing another velocity vector for the seed point; selecting an incremental distance in a direction of the another velocity vector; computing coordinates for another new seed point location based on the incremental distance and the direction of the another velocity vector; computing an incremental time of flight for each incremental distance based on a velocity for each respective velocity vector and the respective incremental distance; mapping a color for each incremental time of flight to each respective incremental distance; computing an accumulated time of flight; adjusting the accumulated time of flight to zero at an end of the streamline nearest an injection well; and displaying each color representing the accumulated time of flight on the streamline between the end of the streamline nearest the injection well and another end of the streamline nearest a production well or a stagnation region.
