Bati Raman Oil Field is Turkey’s largest oil reserve (1.85 billion barrels). It is situated at an average depth of 1450 m, producing 12° API heavy oil (very viscous) from a 60m thick calcareous reservoir rock. The recovery by primary oil production method and even with different Enhanced Oil Recovery (EOR) techniques (water flooding, steam flooding, and CO2 injection) has been limited to 9%. One of the plans for the production of Bati Raman oil is to use Mining-Assisted Heavy oil Production (MAHOP). In this method, multiple shafts and declines are excavated from the surface to the reservoir and a series of excavations (galleries) continue along the bottom of the reservoir. Fan-shaped steam injection and production holes are drilled in the reservoir from the crown of the galleries for the use of conventional Steam-Assisted Gravity Drainage (SAGD) for oil production. This research aims to design the mine conceptually using the Micromine Software package, evaluate the challenges; such as tunneling practice, steam supply, ventilation, and tailing disposal, and create an economic model of the mine. For a production rate of 250K barrels of oil /day, the NPV and IRR of the project are found to be 6.5 billion $ and 23%, respectively. Operating cost is estimated to be 32.32 $ per barrel of oil while initial capital investment is estimated to be 5.36 B $. The sensitivity analysis showed that the project is most sensitive to the oil price which is assumed to be 70 $ per barrel oil for the base case.
