Pyrolysis System for Source Rock Evaluation

The patent applies parameter changes by systematically varying temperature, pressure, and chemical composition parameters during pyrolysis experiments to match subsurface conditions. The method uses multiple heating rates and temperature profiles to simulate different burial histories and maturation conditions, thereby improving both measurement precision and environmental reproduction reliability

The patent creates a simplified laboratory copy of the complex subsurface environment by using surrogate materials and scaled-down experimental conditions. The pyrolysis apparatus replicates key subsurface parameters (temperature, pressure, fluid composition) without requiring actual subsurface conditions, enabling accurate measurement of kinetic parameters that can be extrapolated to field-scale hydrocarbon volume predictions

The patent implements feedback mechanisms by continuously monitoring pyrolysis product generation rates and using this data to refine kinetic parameter estimates. The method compares experimental results with simulation predictions and iteratively adjusts kinetic parameters to improve agreement, thereby enhancing both productivity and measurement precision simultaneously

The patent performs preliminary pyrolysis experiments to determine kinetic parameters before conducting full-scale computer simulations. By obtaining accurate kinetic properties through controlled laboratory pyrolysis first, the method enables more efficient and accurate hydrocarbon volume predictions in subsequent simulation stages, improving overall evaluation productivity
