Abstract
A system for determining shale rock maturity includes a dual mode microwave cavity configured to receive a shale sample, a heating system configured to heat the shale sample to a range of different temperatures using microwave emissions of a first frequency, and a measuring system configured to measure a complex permittivity of the shale sample using a microwave signal of a second frequency.
Claims20
A system for determining shale rock maturity, the system comprising:
- a dual mode microwave cavity configured to receive a shale sample;
- a heating system configured to heat the shale sample to a range of different temperatures using microwave emissions of a first frequency;
- and
- a measuring system configured to measure a complex permittivity of the shale sample using a microwave signal of a second frequency.
A method for determining shale rock maturity, the method comprising:
- measuring a complex permittivity of a shale sample as a function of temperature;
- obtaining an imaginary part of the complex permittivity;
- and
- determining the shale rock maturity based on a relaxation in the imaginary part.
A non-transitory machine-readable medium comprising a plurality of machine-readable instructions executed by one or more processors, the plurality of machine-readable instructions causing the one or more processors to perform operations comprising:
- determining a shale rock maturity of a shale sample based on a relaxation in an imaginary part of a complex permittivity,
- wherein the complex permittivity of the shale sample is a function of a temperature of the shale sample.
