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.

Selection of the stimulation target in unconventional shale formations is an important factor that impacts well productivity. In thick unconventional formations, it is essential that operators quantify the production of each stage of hydraulic fracturing executed in the well, in order to establish the most productive rock. It is also important for operators to be certain that every section of the stimulated well is effectively contributing to overall well production and clean-out of all stages has been achieved. In addition, other development challenges include optimal spacing between perforation clusters, stages and wells, allowing operators to optimize drilling and completion costs and maximize enhanced ultimate recovery (EUR).

This Blog describes the application of chemical tracers in a multi-stage horizontal well to gain insight on stage productivity in order to plan an optimal field development strategy.

Tracerco, patented, pioneered and continues to enhance technology that enables the measurement of individual gas, oil, and water stage production along the length of a wellbore, without well intervention. This inexpensive technology provides confirmation that a wellbore is open to flow, identifies and quantifies stage flow contribution of each phase, and provides measurement of drainage area connectivity - simply by adding small amounts of unique chemical tracers to each stage’s stimulation fluid.

A customer wanted to test two different lithologies and compare the performance of both, in the gas window of the Neuquén Basin, in Argentina. For that reason, a slanted two-horizon target well was drilled, distributing 10 stages in the upper zone, and 10 stages in the lower zone. The intermediate zone, which was not considered a main target, received one stage.

21 unique organic gas and water tracers were added to each of the different stages of the well during stimulation. The injection was controlled and care was taken to tag all stages in the same way, ensuring that the tracers would penetrate deep into the fracture structure and make contact with formation hydrocarbons. Subsequent flowback and sample analysis for the presence of the injected tracers allowed relative gas and water flow from the different stages to be evaluated.

The oil and gas industry is faced with difficult trading times and low oil prices are predicted to continue. Operators and service companies are faced with lower margins and less capital available when making decisions on reservoir production strategies. Working with reduced resource is difficult enough, but production targets still must be met.

In order to meet these challenges a number of different innovative technologies have been developed and tested in the field that assist with reservoir production optimisation at reduced costs when compared to conventional methods. As an example, the use of speciality chemical technologies can eliminate the need to carry out costly production logging and gain critical data on fluid flow which in turn can be used to optimise development plans.

The technologies can measure clean out efficiency, pinpoint areas of fluid flow, and ultimately log production rates from various zones. All of this data can be obtained throuhg reservoir tracers without the need for intervention the cost of which can run into the hundreds of thousands or even millions of dollars when looking at a sub-sea development. What’s more, this data can be taken on-stream and over several years, saving on rig time as the technology is integrated  down hole when running the lower completion into the well.

Below we will examine the steps you can take applying this alternative technology to make significant savings on rig time.
