I got to check it out. Thanks!

Geopsy is an open source that you can work on your MASW data with, if you need any help on how to work with geopsy contact me on whatsapp 00213791223656, I'll be happy to help & share my knowledge with you. Good luck

Do you sell in United States?

Wouldn't the foreigners have to do 14 days quarantine?

Would it make much difference? 14 days pass really fast.

It looks really compact for two antennas. Great one!

Polarcus seems to follow the fate of Dubai where its headquarters is.

This is a prediction made in 2015, don't know whether it's still accurate. The unconventional supply doesn't take a big percentage. I guess there is still a lot conventional reserve left. world oil supply and demand.png https://www.sciencedirect.com/topics/earth-and-planetary-sciences/unconventional...

Hi Maybe you should take a look at Geopsy, I'm not sure how good it is on its results, but it has a tutorial to process MASW. I usually works with PARKSEIS. You can download the software right from their page. I'll give you a link of the tutorial to MASW http://www.geopsy.org/wiki/index.php/Active_...

Crude oil price is close to $40 now. I am optimistic.

What is HDR? High dynamic range. Basically it means it can have better effective penetration depth by reducing random noises through oversampling and stacking. I believe Mala, GSSI and Sensors&Software are all using the same techniques now (although they might have different names for it) for their...

I am afraid there is no free MASW software. I would be happy if there is an educational version.

I recommend Mala Easy Locator Pro Widerange HDR. This is a dual frequency system with the HDR technology. The two center frequencies are appropriate for underground utility locating. GSSI had a dual frequency system, but in my opinion they chose the wrong center frequencies. It's before HDR tech any...

The United States is sitting probably the biggest geothermal reservoir in the world around Yellowstone National Park. If it blows up, half of the continent might be put into misery. But apparently it's off limits for development.

Sometimes you can see pretty neat GPR profiles. These two profiles are perpendicular to each other in the same survey area.

It reminders me a Twitter message by Dr. Lucy Jones above love wave:

Worst seismology joke: A seismologist investigated strange signals showing up at a seismic station and found a couple making Love waves.

I always love color-coded contour maps such as those provided by refraction tomography. The software we use probably are not as powerful as those used in oil and gas industry, but are convenient for us to use for smaller scale engineering surveys:

Aha! It makes sense. The refraction method is easier in terms of data processing, especially when you don't have the computing power we have now. So it actually can be used first.

I didn't know seismic refraction surveys can be useful for seismic reflection data processing, very interesting. We use seismic refraction in engineering field very often. Was the seismic refraction method invented for helping seismic reflection data processing in the beginning?

At its annual shareholder meeting on Wednesday, the biggest US oil producer Exxon Mobil said it had not yet taken steps to reduce its workforce.

ExxonMobile has actually cut down their expenses in environmental cleanups. This is their first step.

Geovizer is not popular in the states. You probably have a much better chance to find a Geonics EM31 or EM38. It's not cheap, but I don't know how much Geovizer costs and what your friend's budget is. https://www.rtclark.com/product/geonics-em31-mk2-ground-conductivity-meter/ https://www.rtclark.com...

There is also a disconnection between geophysics software and their users in near surface geophysics. While software makers make many options/parameters available for data processing such as in resistivity and ground penetrating radar, etc, many users don't know how to use them effectively because t...

I never used it. But I took a look at their website. It should be a frequency domain conductivity meter, like Geonics EM31. Since it is multi frequency, actually it’s more like GSSI EMP 400, which was discontinued.

According to Houston Chronicle: The oil and gas industry shed a record-breaking 26,300 jobs in Texas during April as shutdowns related to the coronavirus pandemic cut demand and sent commodity prices to record lows. Drilling, completion, production and related sectors employed 192,600 people in Texa...

I often hear geophysicists complain that geologists take their jobs, but not the other way around. Maybe geophysicists are really geeks and hate to see geologists doing their jobs with minimal understaning about math/physics behind it.

I am surprised that Texas is far from the worst state in terms of unemployment rate. I thought Texas would be hit harder due to the oil price.
Texas is in the middle and Nevada is the worst: https://www.bls.gov/web/laus/laumstrk.htm
