Pore-Pressure for Carbonates
摘要
Pore-pressure and stress distribution are coupled; pore fluid pressure affects the petrophysical properties of bulk rock and is a drive mechanism for hydrocarbon production. Rock pore-pressure also affects the strength of the rock (faulted, fractured or intact). When pore-pressure higher than the normal pressure is found (over-pressure), it could endanger drilling operations and narrow the operative window (OW), constraining the drilling mud weight.
