| | Abstract | | Oil recovery rate is as low as about 20 to 40%, and regeneration of declining oil fields is requested. A new oil well is needed for oil recovery that remains in the subsurface, but the spatial resolution of the density distribution by the conventional methods is not necessarily high enough to make a decision on the position of the oil production well. Therefore, using elementary particle muons contained in cosmic rays, we clarify the possibility of monitoring the density distribution of petroleum reservoirs. The overall flow of the research process consits of three parts: first we quantitatively investigate the trade-off relationship between time resolution, spatial resolution and accuracy of muon exploration, and then based on the results we select several specific production scenarios, and then conduct theoretical simulations for muon observations according to each production scenario. The present preliminary study demonstrates the sensitivity of the muon observation in terms of the density length and shows some simulation results of theoretical muon observation for some simplified models. |
