Description

The original version of TOUGH (Pruess, 1987) requires a large amount of CPU time for large 2D or 3D problems. This has prevented us from using the original TOUGH on several actual field simulations. Therefore, we have modified the original TOUGH to make less CPU time and allow us to use new TOUGH on large problems. For reducing the CPU time, two new matrix inversion methods were implemented on the original TOUGH. In this report, first we summarize new matrix inversion method implemented in new TOUGH and second we show inspection results of the accuracy and improvements of speed, and ... continued below

In this report, first we summarize new matrix inversion method implemented in new TOUGH and second we show inspection results of the accuracy and improvements of speed, and then we show the case study results. Before conducting this case study, the porous medium model for the case study is optimized. As the case study we tried to analyze build-up data acquired by PTS (Pressure/Temperature/Spinner) logging in a two-phase condition. We have been successful in obtaining a good match to PTS data.
