    Simulation protocol of water shut-off treatment for gas storage reservoir in Guantao Field (China)
    (2023) Benallaou, S.; Eladj, S.; Doghmane, M.Z.; Keltoum Benabid, M.
    Nowadays, oil and gas wells can produce excessive amounts of water in many fields. Excessive water production reduces oil and gas productivity by leading to fines and causing sand production and the corrosion of surface facilities. The combination of these unfavourable phenomena results in the early closure of wells as oil and/or gas production becomes unprofitable. In this study, a methodology for simulating water shut-off (WSO) treatments was tested on three synthetic reservoir models in order to conduct sensitivity studies on various parameters affecting the WSO treatment, such as polymer solution type, volume, and injection rate, for the purpose of evaluating different treatment scenarios, defining an optimal treatment design, and forecasting post-treatment well behaviour. Moreover, this protocol explains in detail the different stages of the reservoir simulation methodology for sensitivity analyses and describes the interpretation of WSO treatment results which enable the study of its application feasibility in a real field.
