Short AnswerHow would the P-wave velocity of a porous, water-saturated sandstone change if some of the water were replaced by natural gas? When a P-wave strikes the interface between two rock layers at normal incidence (angle of incidence = 90o), what waves travel on from there, and which way? 2D seismic data are acquired along a 1D line on the surface. 3D seismic data are acquired over a 2D area of the surface. How is 4D seismic data acquired? The acoustic impedance of a rock layer is a parameter that may be calculated from some other common rock parameters. Write down an expression for this calculation in words, not just symbols (unless you define the symbols). What kind of mathematical curve (or function) might we see for the travel-time curve (or function) on a seismic shot gather representing the reflection from the dipping base of a single layer? What do we call a seismic gather in which each trace has the same shot-receiver distance? Write down an equation that expresses Snell’s law. If we have a two-layer situation where V1 = 1950 m/s and V2 = 3900 m/s (P-wave velocities), what will the P-wave critical angle be? 9.
