oa 40 Years Experience of Romashkino Oil Field Development in Tatarstan: Improvements of Water Flooding

The system of contour water-flooding was for the first time introduced in Romashkino oil field, occupying the territory of about 4300 sq.km. The field was divided into 21 independent areas of development by rows of injection wells. This allowed to bring into development the largest fleid by accelerated rates with reasonable economic costs. The following improvement of water-flooding system allowed to achieve oil recovery factor of 47.7% by the beginning of 1994. Currently developed technological solutions for improvement of water flooding will allow to achieve oil recovery factor of about 53%.
