Tracer Technology is used extensively in oil and gas exploration and recovery, and both radioactive and non-radioactive tracers that can be measured at low concentrations are applied. Tracer technology may also apply to geothermal reservoirs for e.g. monitoring flow paths of injected water or leakage into ground water.
Tracinvent proposes to add a new type of tracers to any oilbased product such as lubrication oil. The extremely low level applied will not have any significant effect on the physical or chemical properties of the product. The tracers can be used to disclose cases were pirate products have been exchanged with the original quality product. It can also be applied to verify that the correct type of product has been used, for instance the correct oil product
A family of non-toxic tracers can be added in extremely small quantities to edible oil and to wine for authentication purpose. Addition of this type of tracers to for instance olive oil will have no effect on taste or quality. A quantity as low as 10 micrograms per cubic meter can be detetcted.
A new family of single well tracers has been invented. The environmentally acceptable tracers can be used for measuring oil saturation rate in near well studies in petroleum reservoirs. The tracers can be detected at 1 ng/ml using HPLC-FLD, making it possible to reduce the injected amount of tracer by a factor of 100 compared to when the traditional single well tracer ethyl acetate is applied.
Another new invention is a partitioning tracer that is environmentally acceptable and that can be used for partitioning inter-well tracer studies. The tracer can be detected down to 1 ng/ml in produced water using HPLC-FLD. Such analytical equipment can be purchased at a relatively low cost and is simple to operate. It can also be applied in the field unlike the more sophisticated and expensive instrumentation such as a gas or liquid chromatograph with high resolution mass spectrometric detection (GC-MS/MS or LC-MS/MS).
