You guys don't think geophysics is hard enough? Let's keep geophysicists and computer geeks separated. :lol: We are already half way there to be computer geeks. They are hackers of the internet world and we are hackers of the underground world. ;) Actually, we both hack the underground world, only ...

Re: Google Says It Will Not Build Custom A.I. for Oil and Gas Extraction

Geophysics programs for oil and gas exploration in colleges/universities should start having some courses in AI/data science, or encourage some collaborations with the computer science department if they already have the courses.

Re: Geophysicist entering in Petroleum Engineering

The employment of Petroleum engineers is also greatly affected by oil prices, so it's hard to say whether it's a good movement or not. With current oil prices, I don't think it's better than being a geophysicist.

Re: Noise in time-lapse volumes

It's an interesting question. Apparently the time lapse signals are related to how much the earth materials changed between the two time stamps. I suspect the time-lapse survey would not be conducted if a reasonable signal strength is not expected. Systematic noises in general are automatically cut ...

Re: Masters in Geophysics.

Full-waveform Inversion is also considered to be a frontier now. If you can get help from someone (such as getting a source code), you can work on an aspect of it for your Master thesis, such as refining the algorithm to improve the computing speed, etc.

Re: fracknation

Most of the issues reported seem to relate to the wastewater - either as a result of well failures or using the "deep disposal" method of pumping used fluids back into a deep, saline aquifer. The latter seems to be seldom conducting in conjunction with any kind of surveying to identify the potentia...

It's mainly used for education and research purposes. Seisunix is free you can get the source code and play with it. It's not intended for commercial use and of course not as powerful as those commercial softwares.

Re: Physics Graduate Looking for Geophysics

You can look for some short courses at SEG and PetroSkills, but they are not free and most of them are not suitable for starters. If you don't want to get a post graduate degree in geophysics but still like to look for a job in exploration geophysics, the best chance would be working as a field crew...

Re: Crewes: source frequency

I think there is no source frequency involved here. It's ray tracing within a model of fixed velocity regardless of the frequencies. Here is an example: 1. dtstep=.001;%time step 2. dt=.004;tmax=1;%time sample rate and max time 3. xrec=x;%receiver locations 4. zrec=zeros(size(xrec));%receivers at ze...

Re: Salary onboard a seismic vessel

OK, it's the impression I got over the years from my colleagues. The salary doesn't sound very good, but in general it should be tax free money. And 50/50 on and off is good for a lot of fellows.

A state of the art seismic vessel would cost around 200 million dollars. I would expect a vessel 10 or more years old would be worth at least tens of million dollars.
