Tracer technology is proven to be critical to assess remaining oil saturation measurement in a reservoir following secondary recovery. It allows the measurement of remaining oil saturation between wells, rather than just surrounding a wellbore. This technique is normally used before and after an Enhanced Oil Recovery (EOR) project to establish changes in crude oil saturation.
In this blog we will discuss using a case study example, how our range of specialist chemical tracers can allow operators to identify the amount of remaining oil saturation in a mature waterflood and determine the effectiveness of specific enhanced oil recovery techniques at reducing remaining oil to residual levels.
