الملخص

In recent decades, the demand of energy is growing sharply. Oil plays a very important role among all of the energy resources. Low permeability oil reservoirs classified as non conventional oil reservoirs and needs special techniques for oil recovery. The primary aim of this study is to select a proper technique for oil recovery of low permeability carbonate oil reservoir. Different carbonated and non-carbonated brines were employed in this project. Formation brine (17500 ppm), carbonate formation brine, sea water, low salinity water, carbonated sea water (50000 ppm), and carbonated low salinity brine (5000 ppm) were used in this work. Core samples were grouped as composite cores with overall average permeability similar to the reservoir permeability. Four sequential low salinity water flooding systems were studied in this project. The following four different sequential water flooding systems were tested: (1) FW-SWLSW- car LSW, (2) car SW-SW-LSW, (3) car FW-FW-SW-LSW, (4) car LSW-LSWSW. In general, the results of the experimental work indicated that Carbonated Water performs better than non-carbonated water. Carbonated Low Salinity water is the optimum brine among all tested brines in terms of oil recovery. A sequential composite core water flooding consists of car LSW- LSW-SW is the optimum sequential flooding system among the studied systems. The interfacial tensions, contact angle, and end point relative permeability results indicated that wettability is the dominant oil recovery mechanism of the studied systems.
