    • Accurate RMS velocity determinations from CGP data by measuring residual NMO with an adaptive method 
      Yang, Sung Jin (Texas A&M University. Libraries, 1976)
      Accurate root-mean-square (RMS) velocities are needed to stack a common-ground-point (CGP) gather properly, to calculate interval velocities, thickness, and dips of subsurface layers accurately, and to infer correct ...
    • Effect of volatiles on seismic attenuation and velocity in sedimentary rocks 
      Clark, Virginia Ann (Texas A&M University. Libraries, 1980)
      Small amounts of water can have a dramatic effect on the seismic quality factor, Q; this suggests the importance of controlling the environment in which Q measurements are made. Because the effect of moisture is so large, ...
    • Linear vibrations of porous media 
      Pride, Steven Randolph (Texas A&M University. Libraries, 1991)
      In this research, the equations of motion of an isotropic fluid-saturated sedimentary medium are developed from first principles. The equations are limited to the case where linear stress/strain relations are adequate for ...
    • One-dimensional iterative inversion of vertical seismic profiles 
      Dillon, William Gregory (Texas A&M University. Libraries, 1985)
      In a vertical seismic profile, the earth's response to a surface excitation is measured by geophones located in a borehole. The objective of this research has been to use the recorded up and downgoing waves to estimate ...
