Capillary pressure curve from mercury intrusion method.

Summary[edit]

Description
English: Capillary pressure curve from mercury intrusion method, that is, mercury penetrates the core sample.

Three key pressure points are of interest for estimating petrophysical properties or facies classification: Entry pressure (Pe): indicates the entry point of mercury in the largest pore throats of the core pore space. Displacement pressure (Pd): indicates the first interconnected pore throats that mercury displaces inside the core pore space.

Threshold pressure (Pthr): indicates the point at which mercury penetrates throughout the core pore space, i.e., pressurised mercury breakthrough the most interconnected pathway inside the sample.
