Abstract

The fluid factor (DF), Poisson impedance (PI), and lambda-rho (λρ) are three Previous HitseismicNext Hit attributes commonly used to predict pore fluid and lithology. The pore-fluid sensitivity of these attributes was evaluated with both well-log and Previous HitseismicNext Hit data in Tertiary unconsolidated sediments from the Gulf of Mexico. While the sensitivity of one Previous HitattributeNext Hit versus another to discriminate pore fluid is often debated, the sensitivity of the three attributes are not independent but can be traced back to the fluid factor. The three attributes along with their statistical distributions for different pore fluids were measured in 183 reservoirs and then used to quantify the Previous HitseismicTop amplitude in a 3D survey to “true” reflectivity values thus allowing pore-fluid classification.
