The use of Partitioning Interwell Tracer Test is examined in the current thesis through the scope of black oil and chemical simulators (ECLIPSE and UTCHEM). Tracer tests have been thoroughly applied over the past decades as a means of reservoir characterisation. Partitioning Interwell Tracer Test is considered as a useful method for estimating oil volume and oil saturation, particularly before the application of Enhanced Oil Recovery methods, where the remaining oil saturation is close at its residual value. The accuracy of such predictions is investigated through the usage of ECLIPSE and UTCHEM simulators. Also, a sensitivity analysis to oil saturation distribution is conducted with regards residual oil saturation estimations. As chemical compounds, it is important to determine whether tracers’ transportation in the porous medium is sufficiently described through the equations that are provided in the aforementioned simulators. The latter are not meant to fully encapsulate all the probable mechanisms and reactions that may occur as tracers are injected into the reservoir and flow across the rock material. Numerical methods are also examined in the case of reservoirs that oil exhibits a non-residual saturation value. Furthermore, the use of partitioning tracers is investigated in heterogeneous reservoirs as well as in naturally fractured reservoirs as a qualitative means that may lead to useful information about flow patterns that cannot be easily deduced solely from production data themselves.
