Help me with 3D seismic planing PLEASE

[antonio131313]

Dear geophysicist!
Could you say me how I must plan reciever lines in 3d seismic? Along or across aim strucure?
Do you have ane books, articles about 3d planing?
Send me, please.
Thank you!!!

U should locate one of your lines (RL or SL) across a structure. for geophysical aspects It does not mater what kind of line u locate along but it's impotant for economics of the project because number of SP defense from it

to Refraction.
Thank you, for your answer!

HI Refraction
are u familiar with GMG mesa?

[Refraction]

Hello dafenshi!

I'm not a guru but I use this software for last 6 or 7 years from version 5. If u have any questions. I try to answer how soon as it's possible with my pleasure. I'm also developing a software for moving templates automatically. it will ready after a few weeks
all the best

you have to put the receiver lines across the targeted structure.

Dear bangades
You are right. But this rules is right for 2D seismic because otherwise you never see how horizons move. For 3D we can take a slice for any direction along reciver line, across it or another angle. Also we are gathering data by CMP bins and one bin includes many azimuths and many offsets.
according aforesaid only bearing important for line allocation

Dear Refraction,
is it possible in 3D seismic survey, to put the shot lines adjacent to receiver lines? if possible how will you implement this when you're making the template in Mesa? thank you in advance..

Dear bangades
Sorry for delay. I don’t understand your question, because I’m a new guy in English language. If you ask me again but use simple and exact words I try answer to you with a maximal accuracy. However, I suppose you asked may we use a same bearing for receiver and source lines. I answer yes, Why Not. How you know most popular seismic design in world is orthogonal design where source lines are allocated across receiver lines. But there are many another variants like a bricks, zigzag, buttons etc. It
It means that you can lay lines how easy for acquisition, and don’t forget about your geological targets
Best regards

The inlines quality is always better than the crosslines in 3D surveys. So, i would lay the rec lines across the structure.

hi Refraction
is there any way in omega to import the survey data and update .and the import the observer log (real time data) and compare it with survey data in Mesa?
u can mail me at mmgeophysics@gmail.com I have some files and survey we can discus it together.

It's not quite right, we can have a good subsurface sampling as well if we design it in proper manner.
