Mature oilfields are often characterised by increased water production. This results in costly water treatment and reduced oil processing capacity. Unwanted produced water may stem from well integrity failure, wellbore tortuosity, high waterflood injection rates, high permeability channelling, thief zones or injector / producer well spacing as well as water coning. Identifying the source of excessive water production and mitigating for its costly impact is critical during field development in reducing costs and maximising oil production.

Interwell partitioning tracers to measure the effectiveness of a chemical EOR flood

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.
