Underground oil/gas reservoirs are connected in extensive and branched networks. To maximize fuel extraction and minimize drilling costs, oil and gas operators need to understand underground reservoirs connectivity and fluid dynamics. Tracers, either chemical or radioactive, are valuable and widely used tools to map these reservoirs. However, the amount of tracking that can be performed is limited by the number of unique tracers available: We have ~100 unique signatures, clearly insufficient number for complex reservoirs with >200 stages. Besides, these tracers are usually hazardous, need to be carefully manipulated by training operators, and are only detected at high amounts.
To answer this need we, at Well Genetics, have developed TRACEDNA, a synthetic tracer composed of short strands of DNA, the storing molecule of living organisms, which allows for billions of unique combinations. Besides supporting unlimited underground mapping, TraceDNA is innocuous and non-toxic neither for the environment nor for the operator, easy to manipulate, detected at very low levels and the most cost-effective tracer in the market.
