  • SYSTEM AND METHOD OF QUANTIFYING CARBON DIOXIDE STORAGE
    Publication number: 20260098468
    Abstract: The invention provides a system and method of estimating the amount of carbon dioxide stored in a storage formation. The method comprises associating at least one carbon dioxide source with at least one tracer and injecting the carbon dioxide from the at least one carbon dioxide source into the storage formation. The method comprises collecting samples from one or more sampling location and measuring the concentration of the tracer in the at least one sample. The method comprises inferring from the presence or absence of the tracer in the sample the amount of injected carbon dioxide remaining in the storage formation.

  • Tracers
    Patent number: 9856732
    Abstract: A family of organic tracers is proposed for inter-well measurement of residual oil in petroleum reservoirs, as is their use as partitioning tracers in a petroleum reservoir. The tracers consist of at least one benzyl alcohol of formula i) wherein each of R1 to R5 is independently selected from H, F, CI, Br, I, CF3 CF2CI, CFCI2 and CCI3 and wherein at least one of R1 to R5 is not H.

  • System for delivery of a tracer in fluid transport systems and use thereof
    Patent number: 7560690
    Abstract: The present application describes a specific tracer delivery system that has been tested. The claimed system is composed of melamine formaldehyde resin (MFR) doped with various tracer materials. The MFR is used to slowly release tracer compounds into a liquid system. The MFR/tracer mixture is applied as part of a monitoring system where tracer is delivered from the MFR/tracer mixture at a specific location up-stream and detected at some location downstream, thereby verifying fluid flow from that specific location up-stream. The MFR can be doped with different types of tracers, thereby allowing placement of different tracers at several different positions upstream. Production from the various labelled zones can be verified through the analysis of one sample downstream.
