Comparison of processing parameters for generic in situ and surface processes
The objectives of this study are: determine the effect of tailor blasting for uniform processing on the overall performance of a commercial module; identify any obvious process changes that would improve the performance of the overall system; and compare the performance of both current and second generation in situ processing with various surface processing concepts. The following have been accomplished: A simple model for the in situ retort process has been constructed that can be used to estimate process related variables. Comparison studies made using this model indicate that first generation in situ technology performs significantly below optimal surface processing. These studies indicate that the use of steam in the inlet stream greatly increases the power consumption and water requirements of an in situ retorting system. Second generation technology that involves uniform processing offers the promise of significant improvements in the performance of in situ retorting making this technology comparable in process efficiency to surface processing for leaner shales. 9 refs., 7 figs., 1 tab.
