Oil & Gas Webinar - Save Time and Money While Pushing Reservoir Data Handling to New Frontiers
Tuesday 11th September
Kraken is a powerful cost and time-saving reservoir simulation post-processor, originally developed for a key Brazilian client by ESSS, South America's leading engineering simulation solutions company.
It features a modern user interface tailored to the visualization and manipulation of multiple scenarios and data sets from all leading reservoir simulators, within any user workflow.
Join us for a free 1-hour Kraken web event on Tuesday 11th September, presented by Marcos Damiani (ESSS) including a Live Demo of Kraken.
Why penetrable model can be assumed in random?
There is a lot of homogenization theories based on penetrable model or some other name like 'overlapping', 'randomly imbedded model' to analyze random microstructure. In reality, the fibers or inclusions can not be penetrated into each other, so why they use this assumption anyway?
Thanks for your opinion.
The Change of Microstructure at low temperature

Recently, we do some work about the dynamic strain aging. In order to investigate the function of solute clouds and precipitates in DSA, we do some experiments. The solution treated LY12 alloys are tested on MTS at low temperature (173K), and the Portevin-Le Chatelier phenomenon disappeared as we expected. But, we need more information about the change of microstructure under the low temperature, what is more the micro-optical observation should be finished in a very short time when we consider the effect of natural aging. Obviously the TEM can not meet our needs.
