Appropriate use of dissolved gas energy in fields at the final stage of development

In order to improve the development of fields at a later stage, this article considered use water-gas repression together with dissolved gas energy. The theoretical basis study is based on application method physical modeling oil displacement by water. As result, it was found that waterflooding would be more effective when such an activity carried out in early stages development. Waterflooding can also old, depleted shallow depths oil-bearing horizons. states flooded deposits, where reservoir pressure did not drop below bubble point pressure, advisable reduce (to carry forced withdrawal). After that, water injection should resumed 30-50% compensation. It has been established increase efficiency developed mode, must started 30–70% less than pressure. best option for deposits presence active edge waters. If they are absent, end aquifer compensation withdrawals from 20 40% after start extraction oil.
