![]() The methodology has proven to be the best tool for monitoring the performance of both PWI and DFI wells in Minagish Oolite reservoir.īased on the water conformance modeling, the correct decisions regarding the various workover related to water injectors as well as producers were taken to control the injection water movement through faults, channels and high permeability layers inside MO reservoir. ![]() Pressure fall off tests, injection tests and tracer survey analysis used for water front tracking and water injection conformance. In case of MO reservoir the semi analytical model along with Hall plot and its derivative function at sand face is found to be an alternative to pressure transient analysis, The water injection monitoring techniques based on focused surveillance program and semi analytical model has been developed for both DFI (Dump Flood Injectors) and PWI (Power Water Injectors) which is used for improving water flood conformance in MO reservoir. ![]() The layer wise cumulative water injection is calculated from production logs on injectors as well as nearby offset producers. The radius of expanding cool injected water front is obtained by saturation logs (TDT) and layer wise cumulative water injection at various points across the formation. power water injection (PWI) and Dump Flood Injection (DFI).įor water injection monitoring and water front tracking a semi analytical model is developed for MO reservoir based on radius of injected cool water front superimposed over seismic and geological cross-sections to monitor the water front position at real time inside MO reservoir. In MO reservoir, two types of water injection methods are implemented i.e. Minagish Oolite (MO) reservoir is a mature reservoir having long production history along with water injection from several years as a primary means of pressure maintenance. For water floods, through continuous surveillance plan, reservoir monitoring and water front tracking results in improving sweep efficiency and enhancing the overall oil recovery. Water flooding is the most successful and widely used process for effective pressure maintenance and enhancing the oil recovery because water is widely available and inexpensive relative to other fluids, easy to inject, and highly efficient in displacing oil.
