Abstract

Numerical methods are used to simulate difficult cases of exploration geophysics, and, for this reason, it is always necessary to develop fast and efficient computational algorithms to achieve these objectives. In this article, we worked in an one-dimensional (1D) computational algorithm, in order to simulate conductivities well logs, which were collected in areas considered as complex geological environments. The developed program was used to analyse effects in induction well logs, choosing as model several sequences of thin horizontal parallel intercalated layers with high contrast of conductivities (shale–sand), which is a very common geological situation of oil reservoirs and always, in accord with by the petroleum industry, presents difficulties in interpretation. In this form, to perform our modelling, we used ILD, 2C40 and 6FF40 tools, all developed by SCHULUMBERGER and commonly utilised in oil industry. Thus, our results show that focalized tools as 6FF40 have better responses in the studied cases, but, among of them, the values of conductivities and thickness of the layers were always very far from the theoretical models.
