  • Model based inversion of seismic response for determining formation properties
    Patent number: 9542508
    Abstract: A method for characterizing a property of a subterranean formation including collecting well log and seismic data, inverting the data, processing for upscaled petrophysical parameters, constructing a flow model that generates saturation, pressure and temperature, constructing seismic velocity relationships from the results of the flow model, and constructing a seismic model. Some embodiments may form a full waveform model or a ray tracing model. Some embodiments may generate a velocity profile and/or waveforms using the profile. Some embodiments may use the parameters to form a reservoir model or to recover hydrocarbons from the formations. Some embodiments build a reservoir model of CO2 injection or CO2 presence after injection or for simulating CO2 presence in a subterranean formation. Some embodiments may also quantify CO2 properties in the reservoir or predict CO2 profile evolution over time in the reservoir including spatial distribution.
