Leverage absolute residence time assessments of petroleum fluids to gain a better understanding of fluid migration in petroleum and other fluid storage plays.

Gain critical insights & find the answers you’ve been looking for

Through proprietary techniques, reliable data, and high-quality analyses, GeoNap Tracker fills a fundamental gap that exists today in constraining the accuracy of the time of events in petroleum system models.

Backed by years of research and innovation, GeoNap Tracker leverages state-of-the-art technologies to introduce a radiolysis-based method for measuring and providing absolute residence timing of petroleum fluids in reservoirs.

Key Benefits

  1. Get answers sooner, save time and capital.
  2. Reduce risks of exploration and high-capital decisions.
  3. Drive efficiencies with reliable data and expert analyses.

“Until now, there have been no reliable ways to estimate the absolute timing of oil charge in a given reservoir, leaving petroleum systems models largely unconstrained in this way. GeoNap Tracker changes this.” (Renzo Silva, CEO)


+ What are the benefits & use cases for GeoNap Tracker?

Conducting and analyzing the results of a GeoNap Tracker assessment enables you to: * Decouple charges and migration pathways, where different scenarios would fill reservoirs in different time spans.
* Extract the maximum information on the petroleum reservoir system when minimum fluid occurrences are available.
* Constrain petroleum system models.

+ What data, samples, or other information is required?

The following data/samples should be provided for best results:
* Produced or DST oil or condensate samples.
* Gamma ray well-logs and/or radionuclide abundance, if measured.
* General reservoir properties*

*These can be estimated if they are not readily available.

If no sample information is provided, we can still run our methods and provide results which can be highly-valuable for our customers. Of note, however, is that with no supporting information, our capability for troubleshooting will be limited.

+ What should I expect and how will results be shared?

Once the assessment has been conducted, our method outputs are quite straightforward to interpret. Your samples will be positioned within the plot below, at which point several inferences regarding their reservoir residence times will be made possible:

Our team will guide you through your results in detail to ensure the outputs are meaningful and useful to your company.

+ What are the expected costs for a GeoNap Tracker project?

Costs vary depending on the scope of the project and the number of samples provided. Our rates are determined on a case-by-case basis and we pride ourselves on being both flexible and reasonable. Please contact us if you have any questions; we will be more than happy to discuss your options.
