Ive just spent several days writing methods statements and safety protocols for projects we are bidding on. Theres some hard calls we make when we estimate resources. We need to strike a fine balance between costs and margin and quality. Its an art as often theres no “right way”.

Experience shows me that you get what you pay for.

SSI delivers high quality results at an economic cost.

Using Geophysics in your projects

How to add geophysical techniques to your projects. We are always on the end of the phone or email us to review any issues you may have and offer ways to create solutions with geophysics.Things to keep in mind when considering geophysics

Ways to get good value from Geophysics
1) Do Geophysical surveys because it delivers results not because its a pretty picture
2) Use combinations (more than one geophysical method and physical investigation) and consider more one technique for a solution.

Geophysical Data

grant — Sat, 10 Apr 2010 05:18:08 +0000

Computers and the latest generation of soft ware can now do some wonderful things with data. The processing power on a notebook is more than most mainframes had even 10 years ago.

Theres a caution here, much of the procesing and aquisition has been dumbed down… so inexperienced operators and processors get loose on data and can turn a data set from nothing into something that appears to have useful information… They mean well but there many traps for lack of experience across a range of technologies and knowing whats real and what is not.

My rule of thumbs are

IF YOU CANT SEE SOMETHING IN THE RAW DATA THEN USUALLY THE PROCESSING IS SHOWING YOU ARTIFACTS THAT ARE NOT REAL

GET YOUR DATA COLLECTOR/ PROCESSOR TO SHOW YOU THE FEATURE IN THE RAW DATA AND SHOW YOU HOW THEY ENHANCED IT, IF THEY CANT… THEN TREAT THE RESULT WITH A LOT OF CAUTION

Im always happy to look over any modest data sample and give a second opinion

IS GEOPHYSICS BLACK MAGIC

I sometimes wonder that when i go on site i need a large broom and witches hat or maybe a wand, ive been offered divining sticks, metal rods, wooden bits of tree and even just straight arm waving… and the MAGICIANS are so so convinced their divining methods work, maybe it does??

GEOPHYSICS is not magic its sound science and backed by a lot of experience… we get good results and we solve the issues
