Impact of Channel Incision on Kareem Sand Compartmentalization and Water Flooding Variability in the Badri Field: A Case Study in the East-Central Gulf of Suez, Egypt

Abstract

Abstract Badri field is located in the east central part of the Gulf of Suez made up of two productive reservoirs: Belayim and Kareem of Miocene age. This study focuses on the Kareem reservoir, whose production began in 1983. Kareem is largely supported by peripheral and gas cap water injection. However, we observed that some of the water injectors are not in full communication with the offset producers and gas cap water injection had limited success in maintaining reservoir pressure and was ineffective in reducing gas-oil ratios (GOR) or preventing gas migration, as evidenced by the pressure and production data analysis. Following a thorough investigation, the problem identified to be an incised channel, which separated the injectors from the producers. The geological analysis has had a significant impact on reservoir development, influencing water flood strategy, pattern orientation and expected performance, where the geomorphological model of incised channel provides guidance in the selection of alternative water injection locations to improve recovery and overall ineffective water injection program. Due to incision, Baba sand is opposite to Kareem sand. Therefore, Baba sand inside this incision is likely to be Gas bearing with same pressure as Kareem. This has confirmed from few producers when we perforated Baba. Still there are some potential of Baba to perforate as long as it is within incision. Constructed a distinctive AI-ML based reservoir facies 3D model for the Badri field allows understanding internal complexity of reservoir and develop a full field 3D static model that used as a general reservoir management tool to improve expected recovery.
