| Resumo: | Originaly, in the the oil’s reservoiors there is your own energy called primary energy which goes down by the time, so needs some help, called advenced recovery method, that aims to get better the productivity of the well, and there is one which is called Gas Assisted Gravitional Drainage process (GAGD). This process is based in inject gas on the reservoior’s beginning with vertical wells that makes the production raise much more than before, and below this wells there are horizontal wells, but this method just makes the execution better when the wells are matures and with light oil. So, to use this method was built a fluid model and a reservoior in the Winprop in the Computer Modelling Group (CMG), and with the Builder was made three kinds of configuration to analise better the raise the wells’ production. The GEM did the simulation in twenty years, and the Results Graph helped in the graph’ analise, with parameters that make sense, like Recovery Factor, Oil satutation, differents kind of deth, diferentes kind of rate, and cumulative oil. Therefore, this analyses made us realize that the results shows that the oil recovery raises better using CO2 injection with the method GAGD, than using just the primary energy, in this way, the best results are in the configuration that there are six injectors and two productors. |
