Riyami (PDO) SUMMARY The subject field is a fractured carbonate reservoir located in the Ghaba Salt Basin in Oman containing heavy viscous oil. The field was discovered in 1972 and has been producing since 1976 through a process of mainly fracture depletion and natural water-influx. Without the application of an EOR technique the recovery will be low as the processes that displace oil from the matrix reservoir rock are adversely
