  • Patent number: 10808499
    Abstract: Methods and systems that provide ways to detect the hydrocarbon flow while eliminating the hydrogen darkening effect in the downhole environment by separated strain and temperature measurement. The methods and systems use fiber optic sensing cables for real-time detection of hydrocarbon fluids (oil, gas, condensate or combination) in oil and gas wells, for example in cemented annuli between either a rock formation and a casing string, or between a larger diameter casing string and a smaller diameter casing string, or in a cement plug left in the well upon abandonment. Hydrogen darkening-resistant temperature and strain sensing fiber optic cables can be used in conjunction with hydrocarbon sensitive polymers to monitor hydrocarbon migration in the oil and gas well and/or to identify the zone(s) from which the hydrocarbons are flowing.
