Question
Initial parameters are assumed, then iteratively updated based on the extent of model deviations, in the "parametric" or "sparse-spike" method of this task. For 10 points each:
[10h] Name this seismological task. It is classified as pre-stack or post-stack depending on if it is done on migrated or unmigrated data.
ANSWER: seismic inversion [accept word forms like inverting; or sparse-spike inversion; or parametric inversion; or pre-stack inversion; or post-stack inversion]
[10m] Simultaneous inversion involves inferring both this quantity of rock and acoustic impedance, which is equal to this quantity times seismic wave velocity. The bulk form of this quantity accounts for both interparticle void volume and pore volume within rocks, unlike its grain or particle form.
ANSWER: mass density [or bulk density; or grain density; or particle density]
[10e] For a seismic wave crossing an interface between acoustic impedances Z1 and Z2, the coefficient of this process is Z1 minus Z2 over Z1 plus Z2. At an interface, a seismic wave undergoes a combination of refraction, transmission, and this process.
ANSWER: reflection [accept word forms like reflect; accept reflectance or reflectivity or reflection coefficient]
