1. Is your region appropriate for passive surveys?
2. What is the cost of a passive tomography investigation?
3. Is the data obtained less accurate than those of a conventional seismic reflection survey?
4. Why Passive surveys should be carried out at the initial exploration stages?
5. How long does it take to conduct a 3D passive investigation?
6. How sure can we be about the accuracy of the results?
7. What kind of equipment do you use?
8. How many earthquakes need to be recorded to obtain a sufficient resolution?
9. How do you manage so many waveforms?
10. What would you do in the case that the microearthquakes originate from a few, single active faults?
11. Do all the microearthquakes have to originate only within the area of interest?
12. How long can a seismograph be operated for in regions with no electricity?
13. Can you apply this methodology in areas of very rough topography?
14. What about environmentally protected areas such as swamps, tropical forests etc?
15. Can you operate offshore?
16. Can PST methodology be applied to regions where we already have poor quality conventional seismic (2D or 3D) data in order to improve them?
17. Can we apply the PST methodology to areas with high noise (industrial etc?)
18. Can you combine PST results with the results of Gravity and MT surveys?
19. Can PST methodology differentiate oil and gas reservoirs?
20. Can the PST methodology be used for shale fracking and reservoir monitoring?
21. Can we perform a passive seismic tomography survey over a very restricted area?
22. How easy is it to interpret PST results?
23. How sure can Landtech be that the technology works?
24. Is there any relation between the so called Low Frequency Passive Seismic (LFP) method (or direct hydrocarbon indication) and Landtech’s Passive Seismic Tomography (PST) method?
25. Can the Passive Seismic Tomography (PST) method be used for pinpointing hydrocarbon reservoirs and drilling sites with reduced well risk?
26. What are your guarantees?
27. How do you manage to keep a seismological network consisting of so many recording stations in perfect working order 100% of the time?
