The evaluation method establishes an evaluation model for residual hydrocarbon of post- to over-mature source rocks without relying on immature to sub-mature samples."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Evaluation method for residual hydrocarbon of post- to over-mature marine source rocks","description":"An evaluation method for residual hydrocarbon of post- to over-mature marine source rocks includes the following steps: establishing a hydrocarbon generation potential evolution profile and a hydrogen","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11499957","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
