... to 120 bars. All this led to reduction of annual oil decline rate from 30% to 5%. Thus, profound impact is observed from the water injection below the oil water contact. That was challenging task to develop such a formation with tight matrix blocks and high angle fracture system. Fortunately, right...

... of the productive horizon. To increase sweep efficiency and introduce fractured reservoirs into development, it is necessary to use gas enhanced oil recovery (EOR) technologies. To find the optimal technology in terms of technological complexity and efficiency, three technologies were compared: Water Injection (WI...

... of fractures, hereby, planned stimulation measures were cancelled in spite of low injectivity. In addition, falloff tests give additional information on how waterflooding is effectively carried out. Another case which was under active discussion includes the issue of converting a well to water injection, so we...

... characterized by ultralow permeability formation. Thus, recently, four producers were converted to water injection along with the fact that the injection is performed using low-salinity water. Surprisingly, injectors' rates are high enough, current voidage replacement ratio is sufficient and the results...

... Abstract The water-injection induced fractures are key factors influencing successful water injection development in the extra-low permeability reservoir. As water flooding, the water-injection induced fractures have the distinctive characteristic of dynamic fracture growth, which fasten...

... cumulative oil production values with the lower water injection and water production rates. The relatively high expenditure linked with installing intelligent completions within wells drive further the importance to apply and study the advantages of this technology on multiple, diverse cases coupled...

... in terms of displacement efficiency. Following reservoir stimulation scenarios were considered during the laboratory experiment: the base case (water injection); thermal treatment by hot water injection; polymer flooding; polymer flooding at an elevated temperature. Experiments show that conventional...
