One method includes: subjecting the rock sample to a first effective stress without exceeding the effective stress under reservoir conditions of the hydrocarbon reservoir; measuring a first permeability of the sample at the first effective stress; increasing the effective stress on the sample to a second effective stress without exceeding the effective stress under reservoir conditions of the hydrocarbon reservoir; measuring a second permeability of the sample at the second effective stress; reducing the effective stress on the sample from the second effective stress to a third effective stress without exceeding the effective stress under reservoir conditions of the hydrocarbon reservoir; measuring a third permeability of the sample at the third effective stress; and distinguishing between a natural fracture and an artificial fracture in the sample based on the first and third permeabilities."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Analyzing fractured rock samples","description":"The present disclosure describes methods and systems, including computer-implemented methods, computer program products, and computer systems, for analyzing a rock sample from a hydrocarbon reservoir.","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11530972","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.
