Choose the most suitable word or word-combination.
1. Spread correction/ travel time/ plotting is time required for a seismic wave to travel from the source to storage medium/ sonar/ receptor.
2. Conclusions on presence or absence of hydrocarbons are usually made on the basis of data from impedance/ terrain/ reflection profiles.
3. In reflection method the energy initially propagates/ outputs/ plots downward and at some point times/ encounters / transmits a boundary which reflects it back.
4. In choosing a mean/ transition zone/ source array for a particular storage medium/ acquisition project/impedance one must consider a lot of factors.
5. Seismic data sets/ frequency output/ terrain may help to measure depth of source rock which is needed for construction of highways and big buildings.
6. The eruption of mount St. Helen’s produced a great propagation/ impact/ echolocation on the surrounding environment.
7. The equation contains a number of timing/ variables/ media.
8. The natural gas production rates increased by spread correction/ by incidence/ exponentially as enhanced oil recovery techniques were applied.
9. Seismic waves have lower velocity in solid storage medium/ medium /source array.
10. Tuned air gun array/ transition zone/ frequency output is one of the primary environments for seismic exploration.
