This paper reviews the design and implementation of a full-field interwell tracer program for a giant onshore oil field in Abu Dhabi. The field is under peripheral waterflooding in order to maintain reservoir pressure and provide a mechanism to sweep the oil. However, the existence of strike-slip fault planes juxtaposed across the reservoirs added a variable to the complexity of waterflood management. To improve the understanding of reservoir heterogeneity and reduce the uncertainties associated with major faults, a full-field water-tracer program has been designed.
Introduction
On the basis of the streamline model, unique chemical tracers have been injected in 21 water injectors covering all the peripheral areas; dozens of associated offset producers across the field were selected to monitor the tracer movement.
