Abstract
Currently, the water injection into mature fields (Campo Parahuacu-Ecuador) is generally used to maintain pressures and increase the sweep of oil banks through secondary recovery projects. Due to the difference of mobilities of the fluids during the displacement, viscous interdigitations are formed due to the anisotropic behavior of the permeabilities in the production formation. In the present investigation the use of inflow control devices (ICD), orifice type, in the completions implemented in a water injector well to decrease the effect of the viscous fingers, improving the sweep efficiency in the reservoirs of Petroleum.
For the development of the simulations using ICD, a direct injection model was proposed between a producer well and an injector, using the Rubí software, and to model the behavior of the injection rate using ICD, the NETool software was used.
Through the use of the ICDs, all strata of different permeabilities were injected with the same rate to be able to reach a better profile of the water advance front and decrease the viscous interdigitation, increasing the recovery factor, which increased by 10% , during the application of the PRH-03B injector well to the PRH-13 well system according to the simulated data.
