AI Technical Summary

Benefits of technology

This patented technology describes two methods for simulating flows through subterranean formations: 1) Physically Modeling (PML), which accurately explains how fluids move within porous materials during their passage from one place to another without causing any errors or issues that could affect them). 2) Quantitative Difference Methods(QDM): These techniques involve calculating certain quantities based on specific characteristics such as pressures, speeds, concentrates, etc., rather than just relying solely upon an ideal solution. They also combine these calculations with simulations to provide guidance about producing oil wells efficiently.

Problems solved by technology

This technical problem addressed in this patents relates to improving the efficiency of simulations involving fissile materials such as rocks or soil particles during drilling operations due to their tendency towards crackings caused by pressure differences across faults within the material itself. Current methods have been developed without accounting for any effects from the surrounding environment but they lack precision because they rely heavily upon average values rather than considering specific variables like temperature.
