摘要： The invention relates to a method for determining maximum horizontal stress in an earth formation. The method includes obtaining fast shear wave velocities (V s1 ) and slow shear wave velocities (V s2 ) for various depths in the earth formation, calculating shear wave anisotropy (A data ) using V s1 and V s2 , obtaining vertical stress (Sv) and minimum horizontal stress (Sh) for the formation, representing maximum horizontal stress (S H ) using a parameterized function having at least one parameter and using S h and S v as input, determining a value of the at least one parameter by minimizing a cost function that represents a measure of difference between A data and A pred for the various depths and A pred is predicted shear wave anisotropy determined using S v , S h , and S H , calculating S H using the parameterized function and the value of the at least one parameter, and storing S H in relation to the earth formation.

摘要： Systems capable of seismically investigating the earth can include one or more seismic sources and one or more seismic sensors located on the surface and/or included on a drill string. The seismic sources can include vibratory tools such as a vibratory hammer capable of improving rate of penetration of the drill string into a formation, and/or a vibratory agitator capable of reducing or breaking friction developed within the wellbore. Related methods can include using vibratory tools included in a drill string in seismic investigations, such as while the drill string is on-bottom or off-bottom.

摘要： A method of predicting pore pressure based on seismic data can include obtaining seismic inversion data based in part on seismic data collected from a formation. The method also includes calculating a pore-pressure transform, wherein the pore-pressure transform comprises parameters derived using measured pore pressure data, upscaled sonic logs, and density logs, wherein the pore-pressure transform comprises an objective function to reduce unphysical variations in predicted pore pressure corresponding to depth. Additionally, the method can include adjusting the pore-pressure transform for sampling bias caused by pore pressure measurements being restricted to a plurality of lithologies by accounting for a difference between upscaled seismic velocities and average sonic velocities within each of the lithologies. Furthermore, the method can include generating pore pressure prediction values based on the pore-pressure transform for the lithologies and the seismic inversion data, and modifying a seismic model based on the generated pore pressure prediction values.
