A downhole sampling tool is operated to draw fluid from a subterranean formation into a chamber of the downhole sampling tool. The downhole sampling tool is then operated to discharge the fluid from the chamber while monitoring pressure of the fluid and volume of the chamber. Contamination of the discharged fluid is assessed based on the monitored fluid pressure and the monitored chamber volume."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fluid identification via pressure","description":"Apparatus and methods for assessing contamination of formation fluid.
