Using Water in Secondary Oil Recovery

The method of secondary recovery (water injection and gas) plays an important role in oil production. They maintain the reservoir pressure to support production and ensure the scanning of the oil to increase the recovery rate. However, over time they create big problems. Our job is firstly, to study the secondary recovery processes and adverse effects (theoretically), then we studied the water injection problems, water breakthroughs in the well OMJ723 and presented methods to solve these problems. So, our work focused on evaluating the use of MPBT as a solution for water breakthroughs. After the installation of this tool and the completion of the Wetter Shut-off on 06/02/2016, we noticed a drop in water production of Wc = 60% up to Wc = 15%, but causing a drop in the production of car oil isolated the two water producers and also banned 3396–3402 which produced only 6.40% of the water.
